A boot medium is a device such as disk0: or disk1: in the route processor or CompactFlash disk, which stores the Cisco IOS XR software image, configuration files, and other associated software that is required to boot up the router.

OL-18723-01	March 2009	Initial draft of this document. New feature introduced for the Cisco XR 12000 Series Router.

Prerequisites for Boot Media Migration

The current scenario assumes that all the CompactFlash disks have already been installed into the PRP-2 route processor. However, the installation can also be done without any impact on the router operation by performing the following steps:

•Install the CompactFlash disks into the standby performance route processor(PRP).

---

Note The card must be removed from the chassis, because the CompactFlash disk is located inside the board.

---

•Run the redundancy switchover command to check whether the redundancy is full/NSR-ready(nonstop routing). This ensures that the routing protocol information is replicated on both the active and standby route processors.

•Remove the other peformance route processor and then install the CompactFlash disk.

---

Note Check the Cisco IOS XR Release Notes for the CompactFlash disk size requirements.

---

Boot Media Migration Procedure

Perform the following steps to migrate the boot media from disk0: to CompactFlash disk:

---

Step 1 Download the latest version of Boothelper from http://www.cisco.com. Boothelper software is an additional software that extends the capabilities of ROM Monitor on a Cisco XR 12000 Series Router. With Boothelper, ROM Monitor can load images from both CompactFlash disk and TFTP servers. Without Boothelper, ROM Monitor can load images only from a local storage device such as disk0:, disk1:, or bootflash.

Step 2 The Boothelper file should be placed on CompactFlash disk media.

---

Note Ensure that the same Boothelper file is uploaded to CompactFlash disk media on both the primary and standby performance route processors.

---

Step 3 Execute the cfs check command to check the sanity of the configuration file system. This command is executed to resolve any internal inconsistencies.

RP/0/9/CPU0:12k-A3-CE17(admin)# cfs check

Creating any missing directories in ADMIN Configuration File system...OK

Initializing ADMIN Configuration Version Manager...OK

Syncing ADMIN commit database with running configuration...OK

RP/0/9/CPU0:12k-A3-CE17(admin)#

All the configuration files will also be migrated to the Compact Flash disk. You can take a backup of these files on the FTP or TFTP server before the migration process. Later, you can compare the size of the configuration files when the router runs from CompactFlash disk.

Step 4 Perform system backup on the CompactFlash disk. Only the Cisco IOS XR files are transferred to the new media. The system formats the new media automatically before copying system files. Hence, you must save all the necessary information before initiating the backup procedure.

---

Note The backup procedure can be executed either in synchronous or asynchronous mode. Asynchronous mode gives you access to the console, so you can execute the commands while the process is running in the background. You must avoid making any changes to the configuration during this time, because the backup process transfers all the user and admin configurations to the new device. By default, synchronous mode is used.

---

The entire backup process takes approximately twenty minutes for each device (CompactFlash disk on the standby and primary performance route processor). The process happens without interruption to other operations, so there should be no traffic loss observed at this point.

The following command must be executed as shown below:

RP/0/9/CPU0:12k-A3-CE17(admin)# system backup compactflash: format asynchronous

Step 5 Check whether the system has created a directory structure on the CompactFlash disk on both the performance route processors:

RP/0/9/CPU0:12k-A3-CE17(admin)# dir compactflash:

2095333376 bytes total (1624596480 bytes free)

Step 6 Change the boot sequence on both the performance route processors and ensure that the system is booted from CompactFlash disk.

RP/0/9/CPU0:12k-A3-CE17(admin)# system boot-sequence compactflash:

Info:  node0_9_CPU0: command succeeded.

RP/0/9/CPU0:12k-A3-CE17(admin)#system boot-sequence compactflash: loc 0/8/CPU0

Info:  node0_8_CPU0: command succeeded.

Step 7 Reload the router. You can observe a loss of traffic while the system is booting up. The period of traffic loss depends on the configuration size of Cisco IOS XR software image.

RP/0/9/CPU0:12k-A3-CE17(admin)# reload loc all

Preparing system for backup. This may take a few minutes [done]

Proceed with reload? [confirm]

---

Note There might be some error messages observed in the system log. These messages do not impact the procedure or bootup process.

---

Step 8 Check the system version booted from CompactFlash disk using the following command:

RP/0/9/CPU0:12k-A3-CE17(admin)# sh ver
