2 Prerequisites Creating Disk Backups f the Cisco IOS XR Software and Configurations Prerequisites To perfm these configuration tasks, your Cisco IOS XR software system administrat must assign you to a user group associated with a task group that includes the cresponding command task IDs. All command task IDs are listed in individual command references and in the Cisco IOS XR Task ID Reference Guide. If you need assistance with your task group assignment, contact your system administrat. F detailed infmation about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR Software System Security Configuration Guide. The following additional prerequisites are provided in this section: Disk Backup Prerequisites, page 92 Disk Mirring Prerequisites, page 92 Disk Backup Prerequisites Befe perfming a system backup, the following conditions must be met: The router software must suppt the disk backup feature. The local stage device specified f the backup must be installed. On the Cisco XR Series Router, the suppted stage devices are disk0:, disk1:, and compactflash: (if installed). On the Cisco CRS-1 router, the suppted stage devices are disk0: and disk1: (if installed). Disk mirring must not be enabled. Disk Mirring Prerequisites Befe enabling disk mirring, the following conditions must be met: The router software must suppt the disk mirring feature. This feature is suppted on the Cisco CRS-1 router and Cisco XR Series Routers running the Cisco IOS XR Software, Release a later release. The secondary stage device specified f the mirring must be installed in the same node as the primary boot device. The suppted stage devices are disk0: and disk1:. The secondary stage device must be the same size larger than the designated primary stage device. The secondary stage device must be partitioned. After disk mirring is enabled, you cannot configure the backup disk feature. Note The primary partition on the secondary stage device must be large enough to contain all data on the primary boot device. This can be an issue if the primary boot device has not yet been partitioned. F example, in the situation where both the primary boot device and the secondary stage device are 1 GB in size, the primary boot device contains 950 MB of data, and the secondary stage device is already partitioned to 800 MB in the primary partition and 200 MB in the secondary partition. In such a case, the 950 MB of data from the primary boot device does not fit on the secondary stage device because SMC-92

3 Creating Disk Backups f the Cisco IOS XR Software and Configurations Infmation About Creating Disk Backups of the partition. Such a configuration is rejected and an err is displayed. You need to replace the secondary stage device with a higher capacity device. Refer to Table 11 f infmation regarding disk partition sizes. Infmation About Creating Disk Backups The following infmation is provided in this section: Infmation About the Backup Disk, page 93 Infmation About Disk Mirring, page 93 Infmation About the Backup Disk A system backup disk is created when you back up the system files to a local stage device f the first time. This process fmats the device that you specify, and copies the software packages and system configurations to that device. If the backup operation is perfmed from EXEC mode, then the files from that specific secure domain router (SDR) are backed up. If the backup operation is perfmed from administration EXEC mode, then the files from the administration plane and from all SDRs are backed up. Befe you create a backup disk of the Cisco IOS XR software packages and configurations, you need to determine which device is being used as the primary boot device. The boot device is displayed using the following commands: show version show install active show install committed See Cisco IOS XR System Management Command Reference f infmation on using the commands to determine the boot device. Infmation About Disk Mirring The route process (RP) card in Cisco IOS XR platfms has a primary stage device that is used to ste installation packages and configuration files. This primary stage device is referred to as the primary boot device and is essential f booting the RP and its nmal operation. Disk mirring replicates the critical data on the primary boot device onto another stage device on the same RP, hencefth referred to as the secondary device. If the primary boot device fails, applications continue to be serviced transparently by the secondary device, thereby avoiding a switchover to the standby RP. The failed primary stage device can be replaced repaired without disruption of service. Disk mirring should only mirr critical data on the primary boot device onto a secondary stage device and not any noncritical data such as logging data. To separate critical data from noncritical data, the disk devices need to be partitioned. Disk0: is partitioned to disk0: and disk0a:; disk1: is partitioned to disk1: and disk1a:. Disk0: and disk1: are used f critical data, while disk0a: and disk1a: are used f logging data and other noncritical data. Befe you can configure disk mirring on the RP, you must have partitioned the secondary stage device. The sizes of disk partitions are related to the total disk size, and are provided in Table 11.

4 How to Create a Backup Disk Creating Disk Backups f the Cisco IOS XR Software and Configurations Table 11 Size of Disk Partitions in Relation to Size of Disk Size of Disk Primary Partition Percentage Secondary Partition Percentage less than 900 MB Partitioning not suppted Partitioning not suppted 900 MB to 1.5 GB 90% 10% 1.5 GB to 3 GB 80% 20% me than 3 GB 88% 12% Caution These partition sizes are those suppted by the FAT32 file system. When you partition a FAT16 disk, the file system changes to FAT32. If you might need to downgrade to Cisco IOS XR Software Release 3.7 earlier, consider carefully befe partitioning the disk. Software downgrades to Cisco IOS XR Software Release 3.7 earlier are not suppted f FAT32 disks. The procedure f converting a FAT32 disk to FAT16 is complex and requires the assistance of Cisco technical suppt. How to Create a Backup Disk Creating a New Revised Backup Disk, page 94 Using the Backup Disk to Boot a Router, page 98 Creating a New Revised Backup Disk Complete the following instructions to create a new backup disk, to back up the most recent software and configuration files onto an existing backup disk.

6 How to Create a Backup Disk Creating Disk Backups f the Cisco IOS XR Software and Configurations Step 3 Command Action system boot-sequence {primary-device [secondary-device]} [location {all node-id}] RP/0/RP0/CPU0:router(admin)# system boot-sequence disk0: disk1: Purpose (Optional) Defines the der of local stage devices used to boot a router. Enter a value f the secondary device field to define the default location f system backups. If this field is left blank, the backup device can be defined with the system backup command, as shown in the next step. 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 system boot-sequence command must be installed in the card, the command will be rejected. The primary-device argument defines the default device where software packages are installed and run. This device is also the default location f router configurations. The secondary-device argument defines the device used by the system backup command to back up system software and configurations. This field is optional. Use the location node-id keywd and argument to define the boot sequence f a specific RP. Use the location all keywds to define the boot sequence f all RPs in the SDR. Use this command in administration EXEC mode to define the boot sequence f all RPs in all SDRs. The node-id argument is expressed in rack/slot/module notation. SMC-96

7 Creating Disk Backups f the Cisco IOS XR Software and Configurations How to Create a Backup Disk Step 4 Command Action system backup [target-dev] [fmat] [location {all node-id}] [synchronous asynchronous] RP/0/RP0/CPU0:router(admin)# system backup disk0: disk1: Purpose Backs up the system software and configurations to a backup disk. Use the system backup command without keywds arguments to back up the system software and configurations on the target device f the designated secure domain router shelf controller (DSDRSC) where you are logged in. By default, the backup disk is the secondary device defined with the system boot-sequence command in Step 3. To define a backup device f the current backup operation only, use the system backup command with the target-dev argument. If a target device is not specified with either the system backup target-dev command the system boot-sequence command, then the backup operation is not allowed. Note The target-dev can be any local stage device except the current boot device, and must be large enough to ste the current software set and configuration. To specify an alternate node f the system backup, such as the standby DSDRSC, use the system backup command with the location node-id keywd and argument. To perfm the backup on all RPs installed in a specific SDR, use the system backup command with the location all keywds in EXEC mode. To perfm the backup on all RPs in all SDRs installed in the system, use the system backup command with the location all keywds in administration EXEC mode. Default is synchronous. SMC-97

10 How to Enable Disk Mirring Creating Disk Backups f the Cisco IOS XR Software and Configurations How to Enable Disk Mirring SUMMARY STEPS DETAILED STEPS Complete the following instructions to enable disk mirring. Once disk mirring is configured, if there is a fault on the primary boot drive it cannot be accessed f any reason, control is automatically transferred to the secondary stage device. 1. fmat secondary-device partition [location node-id] 2. Remove any noncritical data from the primary boot device. 3. configure 4. mirr location node-id primary-device:secondary-device: 5. end commit 6. show mirr [location node-id] 7. mirr verify location node-id Step 1 Command Action fmat secondary-device partition [location node-id] RP/0/0/CPU0:router# fmat disk1: partition Purpose Partitions the secondary stage device into two partitions. If the device is already partitioned, you do not need to perfm this step. On multishelf systems, specify the node of the primary boot device with the location keywd. Caution When you partition a FAT16 disk, the file system changes to FAT32. If you might need to downgrade to Cisco IOS XR Software Release 3.7 earlier, consider carefully befe partitioning the disk. Software downgrades to Cisco IOS XR Software Release 3.7 earlier are not suppted f FAT32 disks. The procedure f converting a FAT32 disk to FAT16 is complex and requires the assistance of Cisco technical suppt. Step 2 Step 3 Remove any noncritical data from the primary boot device. configure The primary boot device should contain installation packages and configuration files only. Log files can be copied to the a partition of the secondary device, f example disk1a:. Enters global configuration mode. RP/0/0/CPU0:router# configure SMC-100

11 Creating Disk Backups f the Cisco IOS XR Software and Configurations How to Enable Disk Mirring Step 4 Step 5 Step 6 Step 7 Command Action mirr location node-id primary-device:secondary-device: RP/0/0/CPU0:router(config)# mirr location 0/rp0/cpu0 disk0:disk1: end commit RP/0/RP0/CPU0:router(config)# end RP/0/RP0/CPU0:router(config)# commit show mirr [location node-id] RP/0/RP0/CPU0:router# show mirr location 0/rp0/cpu0 mirr verify location node-id RP/0/RP0/CPU0:router# mirr verify location 0/rp0/cpu0 Purpose Enables disk mirring of the primary-device to the secondary-device. On multishelf systems, specify the node of the primary boot device with the location keywd. If the primary boot device is not partitioned, the following occurs: The contents of the primary device are replicated to the secondary device Control of the mirring server switches to the secondary stage device. The primary device is partitioned. Data is replicated back to the primary boot device. Saves configuration changes. When you issue the end command, the system prompts you to commit changes: Uncommitted changes found, commit them befe exiting (yes/no/cancel)? [cancel]: Entering yes saves configuration changes to the running configuration file, exits the configuration session, and returns the router to EXEC mode. Entering no exits the configuration session and returns the router to EXEC mode without committing the configuration changes. Entering cancel leaves the router in the current configuration session without exiting committing the configuration changes. Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session. Displays disk mirring infmation f an RP node. It also provides the status of the synchronization between the primary and secondary devices. Verifies disk synchronization f disk mirring on an RP node. Note Disk mirring overrides any existing disk backup configuration (Golden Disk), and subsequent disk backups fail. SMC-101
