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.

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:
•
Note
Note
Install the CompactFlash disks into the standby performance route processor(PRP).
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.
Check the Cisco IOS XR Release Notes for the CompactFlash disk size requirements.

Boot Media Migration Procedure
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
Step 3
Ensure that the same Boothelper file is uploaded to CompactFlash disk media on both the
primary and standby performance route processors.
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
Info: node0_9_CPU0: formatting target device
RP/0/9/CPU0:Aug 8 18:30:11.699 : syslog_dev[85]: mkdosfs:

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:
Step 7
node0_8_CPU0: command succeeded.
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
Step 8
There might be some error messages observed in the system log. These messages do not impact the
procedure or bootup process.
Check the system version booted from CompactFlash disk using the following command:
RP/0/9/CPU0:12k-A3-CE17(admin)# sh ver
