For more information about ROM Monitor (ROMMON) and boot tasks, see Cisco ASR 9000 Series Aggregation Services Router ROM Monitor Guide or Cisco ASR 9000 Series Aggregation Services Router Getting Started Guide . config-register mirror mirror pause mirror resume mirror verify reload reload (administration EXEC) show epm trace boot show mirror show reboot show system backup show variables boot show variables system system backup system boot-sequence config-register To define the configuration register boot value, use the config-register command in administration EXEC mode. config-register { value | boot-mode { exec-mode | rom-monitor } | console-baud baud-rate | console-break-key { disable | enable } | password-recovery { disable | enable } } [ location { node-id | all } ] Syntax Description value Hexadecimal or decimal value that represents the 16-bit configuration register value to be used the next time the router is reloaded. Range is from 0x0 to 0xFFFF (0 to 65535 in decimal). For information about common configuration register settings, see Table 1. boot-mode Specifies what to do when the system is rebooted. exec-mode Specifies to load the Cisco IOS XR software and enter EXEC mode on next system reboot. rom-monitor Specifies to enter ROM Monitor mode on next system reboot. console-baud baud-rate Specifies the console baud rate. console-break-key {disable | enable} Specifies to disable or enable the console break key on the next system reboot. password-recovery {disable | enable} Specifies to enable or disable the password recovery mode on the next reboot. location { node-id | all } (Optional) Specifies the RSP node for which to define the configuration register boot value. The all keyword specifies all RSP nodes. Command Default By default, the configuration register value is 0x102 after a Turboboot. Command Modes Administration EXEC Command History Release Modification Release 3.7.2 This command was introduced. Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. The configuration register setting is a 16-bit, user-configurable value that determines how the router switch processor (RSP) functions during initialization. The configuration register can cause the RSP to boot normally from the default configuration, or to enter ROMMON mode during a reload. Configuration register settings can also be used to perform tasks such as password recovery. The config-register command is entered in administration EXEC mode, on the designated shelf controller (DSC) of the system. The DSC is the primary RSP of the owner secure domain router (owner SDR). When setting the configuration register value for the config-register command, note the following conditions: If both the primary and standby DSC are up and running when the configuration register value is set, the configuration register value applies to both the primary and standby DSC. By contrast, if only the primary DSC is up and running when the configuration register value is set and the standby DSC is introduced into the router at a later time, the router does not attempt to synchronize the configuration register value for the standby RSP to that of the active RSP ; in this situation, the configuration register setting applied to the standby DSC is determined by the configuration register value set in ROMMON mode. Note To display the current configuration settings, use the show variables boot command . This table describes the most commonly used configuration register settings. Table 1 Common Configuration Register Settings Value Description 0x0 RSP enters ROMMON mode (rommon B1>) on the next system boot. 0x2 RSP loads the Cisco IOS XR software and default configuration on the next system boot. After logging in, the user can access EXEC mode. 0x102 Router loads the Cisco IOS XR software with the console Break key disabled on the next system boot. 0x40 Router enters the password recovery mode on the next system boot. If you use the various keywords to set the configuration settings, note that the hexadecimal value is updated in an additive or subtractive manner to represent the keyword used. For example, if the current configuration setting is 0x102 and you use the config-register command with the password-recovery enable keywords, the value is updated to 0x142. Task ID Task ID Operations root-lr read, write Examples The following example shows how to set the configuration register on the DSC to 0x2. Setting the configuration registration to 0x2 causes the router to boot the Cisco IOS XR software and enter EXEC mode during a router reload. RP/0/RSP0/CPU0:router(admin)# config-register boot-mode exec-mode Sun May 31 12:10:36.037 PST Successfully set config-register to 0x2 on node 0/RSP0/CPU0 Related Commands Command Description reload Performs a reload of the route switch processor. show variables boot Displays the configuration register setting and boot file setting for the RSPs in the system. show version Displays information about the running Cisco IOS XR software. mirror To configure disk mirroring on a node, use the mirror command in global configuration mode. To disable disk mirroring, use the no form of this command. mirror location [preconfigure] node-id primary-device : secondary-device : no mirror location Syntax Description location node-id Specifies the node of the RP. It can be a node that is not yet installed if the preconfigure keyword is used. The node-id argument is entered in the rack / slot / module notation. preconfigure (Optional) Enables you to specify a node that is not yet installed. primary-device : Specifies the primary boot device used to store installation packages and configuration files. Supported devices are: disk0: disk1: (if installed) compactflash: (if installed) secondary-device : Storage device on the same RP as the primary-device , to where critical data is replicated. Supported devices are the same as for primary-device : , but secondary-device : must be different than the primary-device : . Command Default No default behavior or values Command Modes Global configuration Command History Release Modification Release 3.7.2 This command was introduced. Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. The mirror command replicates all critical data contained in the primary partition of the primary boot device, onto a second storage device on the same RSP . Therefore, if the primary boot device fails, applications continue to be serviced transparently by the secondary device, without having to switch control to a standby RSP . Before the mirror command can be used, the secondary storage device must be partitioned using the command. If the primary boot device is not partitioned, once mirroring is enabled and all data on the primary boot device is replicated to the secondary device, the primary boot device is partitioned automatically. This guarantees that only critical data on the primary boot device is mirrored to the secondary device. Noncritical data, such as logging data, should not be mirrored and should, therefore, be saved to the secondary partition on the storage device. To temporarily suspend disk mirroring without changing the configuration, use the mirror pause command in EXEC mode. Task ID Task ID Operations root-lr read, write Examples The following example shows how to configure disk mirroring from the primary boot device (disk0:) to the secondary storage device (disk1:): RP/0/RSP0/CPU0:router(config)# mirror location 0/rp0/cpu0 disk0: disk1: Related Commands Command Description format Formats a file system. mirror pause Temporarily pauses disk mirroring on a node. mirror resume Resumes disk mirroring on a node after it has been temporarily stopped. mirror pause To temporarily pause disk mirroring on a node, use the mirror pause command in EXEC or administration EXEC mode. mirror pause [ location { node-id | all } ] Syntax Description location {node-id | all} (Optional) Specifies the node of the RSP . The node-id argument is entered in the rack / slot / module notation. The all keyword specifies all RSP nodes. Command Default If no node is specified, disk mirroring is paused on the active RSP . Command Modes EXEC Administration EXEC Command History Release Modification Release 3.7.2 This command was introduced. To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. The mirror pause command temporarily pauses the mirroring of the primary boot device. This command is primarily useful during an installation operation to prevent significant performance degradation on single CPU boards. The mirror pause command does not change the configured state of mirroring, but rather causes the mirroring to be suspended until the mirror resume command is used. The mirror pause command has no affect if the mirror configuration command is not enabled. Task ID Task ID Operations root-lr read, write Examples The following example shows how to pause disk mirroring on the active RSP : RP/0/RSP0/CPU0:router# mirror pause Related Commands Command Description mirror Configures disk mirroring on a node. mirror resume Resumes disk mirroring on a node after it has been temporarily stopped. mirror resume To resume disk mirroring on a node after it has been temporarily stopped, use the mirror resume command in EXEC or administration EXEC mode. mirror resume [ location { node-id | all } ] Syntax Description location {node-id | all} (Optional) Specifies the node of the RSP . The node-id argument is entered in the rack / slot / module notation. The all keyword specifies all RSP nodes. Command Modes EXEC Administration EXEC Command History Release Modification Release 3.7.2 This command was introduced. Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. The mirror resume command resumes the mirroring of the primary boot device after it has been temporarily paused with the mirror pause command. The mirror resume command has no affect if the mirror configuration command is not enabled and the mirror pause command has not been used. Task ID Task ID Operations root-lr read, write Examples The following example shows how to resume disk mirroring on the active RSP : RP/0/RSP0/CPU0:router# mirror resume Related Commands Command Description mirror Configures disk mirroring on a node. mirror pause Temporarily pauses disk mirroring on a node. mirror verify To verify disk synchronization for disk mirroring on a node, use the mirror verify command in EXEC or administration EXEC mode. mirror verify [ location node-id ] Syntax Description location node-id (Optional) Specifies the node of the RSP . The node-id argument is entered in the rack / slot / module notation. Command Default If no node is specified, the verification is done on the active RSP . Command Modes EXEC Administration EXEC Command History Release Modification Release 3.7.2 This command was introduced. To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. The mirror verify command verifies the synchronization consistency between the primary and secondary media devices being used in mirroring. The command verifies that the full contents are identical between the mirrored devices and reports any inconsistencies found. Task ID Task ID Operations root-lr read, write Examples The following example shows how to verify the disk mirroring on the active RSP : RP/0/RSP0/CPU0:router# mirror verify Mirror Verify Information for 0/RSP0/CPU0. ======================================================== Primary device and secondary device are fully synchronized. Related Commands Command Description mirror Configures disk mirroring on a node. reload To reload the route switch processor (RSP), use the reload command in EXEC mode. reload Syntax Description This command has no arguments or keywords. Command Default No default behavior or values Command Modes EXEC Command History Releases Modifications Release 3.7.2 This command was introduced. Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. Use the reload command to cause the RSP to reload the Cisco IOS XR software according to the configuration register setting (for example, 0x0 to enter ROMMON mode and 0x2 to reload the RSP to EXEC mode). If a standby RSP is in the ready redundancy state, the reload command also causes the router to fail over to the standby RSP. Use the show redundancy command in EXEC mode to display the status of the standby RSP . When the reload command is used and a switchover occurs, the running (active) software configuration is automatically maintained during switchover. Caution If a standby RSP is not installed or is not in the ready state, then the router experiences a loss of service while the active RSP is reloading Cisco IOS XR software. To view the status of the standby RSP , issue the show redundancy command in EXEC mode. If you use the reload command and there is no available standby node, you are prompted to continue with the reload: RP/0/RSP0/CPU0:router# reload Standby card not present or not Ready for failover. Proceed?[confirm] y Task ID Task ID Operations root-lr execute Examples The following example shows how to reload the active RSP . If a standby RSP is in the ready state, then the router fails over to the standby RSP . If the standby RSP is not installed or is not in the ready state, then the router enters ROMMON mode and routing operations stop. RP/0/RSP0/CPU0:router# reload Updating Commit Database.

Table 2  show mirror Field Descriptions Field Description Mirroring Enabled Indicates whether mirroring is enabled or disabled. Configured Primary If mirroring is enabled, the configured primary disk for mirroring. Configured Secondary If mirroring is enabled, the configured secondary disk for mirroring. Current Mirroring State Current status of mirroring. Possible values are as follows: Syncing files—Files are being synchronized between the primary and secondary disks. Not Configured—Mirroring is not configured. Mirroring Paused—In this state, no mirroring is being done to the secondary device and the disk redundancy has been removed. The values of the BOOT_DEV_SEQ_OPER and MIRROR_ENABLE variables reflect this. Redundant—The primary and secondary disks are totally in synchronization. Any read or write failure on the primary device results in disk redundancy switchover such that all operations are performed on the secondary device. Current Physical Primary Current primary disk. Current Physical Secondary Current secondary disk. Mirroring Logical Device Device name used by the mirroring process to intercept all application requests to that named device before passing them through to one of the mirrored physical devices. Physical Device Physical disk in router. State Status of the disk. Possible values are as follows: Available—Disk exists in router and is available. Not present—Disk does not exist in router. Partitioning of disks is available only after the disk has been formatted with the partition keyword. Flags Enabled—Disk mirroring has been enabled on this device and the device is part of the mirroring process. Repaired—During the boot, some minor inconsistencies were discovered on the disk and were repaired to make the file system consistent. Formatted—Disk was formatted before mirroring was enabled. BOOT_DEV_SEQ_CONF= ROM Monitor environmental variable for the boot disk sequence. This variable is is set when mirroring is enabled through the mirror configuration command. The devices in this ROMMON variable declare the primary and the secondary devices of the mirroring process. The first device is the primary device and the second device is the secondary device in the mirroring process. Note This variable is also shared by the disk backup feature. This variable can also be set or unset using the system boot-sequence command of the disk backup feature. But the use of system boot-sequence and system backup commands is blocked, if mirroring is enabled. BOOT_DEV_SEQ_OPER= ROM Monitor environmental variable that reflects the state of the disk redundancy status. When mirroring is enabled and the state is redundant, this variable is set to the primary device followed by the secondary device. When mirroring is not in the redundancy state, then this variable is updated to contain only the primary device. MIRROR_ENABLE ROM Monitor environmental variable whose value reflects the mirroring status. If it is set to Y, then mirroring is enabled. If it is set to P, then mirroring is paused. If empty, mirroring is not enabled.

If a target device is not specified, then the secondary device defined with the system boot-sequence command is used. If a target device is not specified with either command, then the system backup command returns an error. The target device cannot be the current boot device. The target device must be large enough to store the current software set and configuration. The supported storage devices are: disk0: disk1: (if installed) compactflash: (if installed) format (Optional) Formats a target disk that already contains a system backup. By default, the command formats the target disk if that target disk does not contain a previous system backup. If the target disk already contains a backup, then the disk is not formatted again. The format keyword forces a format of the target device even if it contains a previous system backup. synchronous (Optional) Performs the command in synchronous mode. This mode allows the installation process to finish before the prompt is returned. This is the default mode. asynchronous (Optional) Performs the command in asynchronous mode. In asynchronous mode, the command runs in the background, and the EXEC prompt is returned as soon as possible. location {node-id | all} (Optional) Specifies an alternative node location for the backup target disk, such as the standby DSC. By default, the backup files are copied to the target device in the current DSC. Use the location node-id keyword and argument to specify an alternative node for the backup files, such as the standby DSC. The node-id argument is expressed in the rack / slot / module notation. Use the all keyword to back up the software and configuration files to all RSPs in the system. Each RP must contain a disk in the specified target device location, such as disk1:. Command Default The operation is performed in synchronous mode. The backup files are copied to the secondary device defined with the system boot-sequence command. The backup files are copied to the target device on the current designated shelf controller (DSC). Command Modes EXEC Administration EXEC Command History Release Modification Release 3.7.2 This command was introduced. Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. Use the system boot-sequence command with the target-device argument to specify the local storage device for backup software and configuration files. The target-device argument is optional and applies only to the current backup operation. If a target storage device is not specified, then the files are backed up to the secondary storage device defined with the system boot-sequence command. If a target device is not specified with either the system backup command or the system boot-sequence command, then the backup operation is not allowed. The target-device can be any local storage device except the current boot device, and must be large enough to store the current software set and configuration. Supported storage devices are: disk0: disk1: (if installed) compactflash: (if installed) By default, the backup is created on the specified target device of the active DSC where the command is executed. To specify an alternate node for the system backup, such as the standby DSC, use the system backup command with the location node-id keyword and argument. To perform the backup on all installed route switch processors (RSPs), use the system backup command with the location all keywords in EXEC mode. Note Each RSP impacted by the system backup command must contain the specified target device. For example, if the system backup command is executed for disk1: on all RSPs in the system, then a flash disk must be installed in disk1: of each RSP . Use the system backup command in administration EXEC mode to back up the administration plane configuration. Use the system backup command in the EXEC mode of an SDR to back up the software and configurations for a specific SDR. Configuration changes are not allowed during the backup process. Any attempts to commit configuration changes are rejected until the backup operation is complete. The backup process cannot be performed during an installation operation. If an installation operation is performed while a backup is in process, the backup operation terminates. Enter the show system backup command to display information about the current backup files. If no backup exists, an error message is displayed. Task ID Task ID Operations root-lr read, write Examples The following example shows how to back up the software and configuration files on a router. The system backup command is run in administration EXEC mode, which backs up both the administration and SDR configurations. The target device is defined as disk1:. The disk is formatted because this is the first backup on the device. RP/0/RSP0/CPU0:router# admin RP/0/RSP0/CPU0:router(admin)# system backup disk1: Info: node0_0_CPU0: formatting target device Info: node0_0_CPU0: copying admin configuration Info: node0_0_CPU0: copying SDR configuration Info: node0_0_CPU0: copying installed software Info: node0_0_CPU0: backup complete. Info: node0_0_CPU0: verifying admin configuration Info: node0_0_CPU0: verifying installed software Info: node0_0_CPU0: verify complete. Info: node0_0_CPU0: command succeeded. Related Commands Command Description show system backup Displays the system backup settings and history. system boot-sequence Defines the order of boot devices used to bring up a router. The secondary device argument also defines the default backup target device used by the system backup command. system boot-sequence To define the order of local storage devices used to boot a router, use the system boot-sequence command in EXEC or administration EXEC mode. system boot-sequence { primary-device [secondary-device] | disable } [ location { node-id | all } ] Syntax Description primary-device Default device where software packages are installed and run. This device is also the default location for router configurations. The value of the primary-device argument is normally disk0: . secondary-device (Optional) Secondary (backup) boot device, used by the system backup command to back up system software and configurations. Supported storage devices are: disk0: disk1: (if installed) compactflash: (if installed) Note The value of the secondary-device argument must be different from the value of the primary-device argument. disable Temporarily disables the automatic recovery mechanism. location {node-id | all} (Optional) Specifies the node of the RSP for which to define the boot sequence. The node-id argument is expressed in the rack / slot / module notation. The all keyword specifies all RSP nodes. Command Default The primary device is disk0: . The (optional) secondary boot device is not defined. Command Modes EXEC Administration EXEC Command History Release Modification Release 3.7.2 This command was introduced. Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. Use the command to define the local storage devices used to boot a router. You can define two devices with this command. The value of the primary-device argument defines the default device where software packages are installed and run. This device is also the default location for router configurations. The value of the secondary-device argument defines the device used by the system backup command to back up system software and configurations. This field is optional. The secondary device can also be temporarily defined when the system backup command is executed with the target-device argument. Use the command with the secondary-device argument to permanently define the secondary (backup) device. Note The primary and secondary device definitions remain in effect until the command is entered again. The value of the secondary-device argument must be different from the value of the primary-device argument. We recommend disk0: as the primary boot device in the boot sequence, and disk1: as the secondary boot device. The boot device specified with the command must be installed in the card or the command is rejected. Use the command in administration EXEC mode to define the boot sequence for the system. Use the command in EXEC mode to define the boot sequence for a specific SDR. Use the location node-id keyword and argument to define the boot sequence for a specific route switch processor (RSP). Use the location all keywords to define the boot sequence for all RSPs in the router . Use the command with the disable keyword to disable the automatic recovery. Enter the show system backup command to display the currently configured boot sequence devices. Task ID Task ID Operations root-lr read, write Examples The following example shows how to define the primary and secondary boot device for the active RSP  (DSC). In this example, the default location for software and configurations is disk0:. The location for backups of software and configurations is disk1:.
