Reinstalling the Cisco IOS XR Software from ROMMON
Reinstalling the Software from a .vm File Located on Flash disk1:
This section describes the tasks required to install the Cisco IOS XR software to the internal flash disk0:
using a .vm image stored on removable flash disk1:. Complete the procedures exactly as described in
this section.
Note Before booting begins, a delay of 10 minutes or more may occur while the .vm image is read to memory
from the removable flash disk1: (DDTS CSCed22546).
Copying a .vm Image to disk1:
All new Cisco CRS-1 routers are shipped with a removable flash disk1: that contains an archive of
bootable .vm files. If these files are not present on disk1:, or if a different version is required, use one of
the following options:
• While the router is still in EXEC mode, copy the necessary .vm image from a TFTP, FTP, or rcp
server to disk1:. This process is described in the “Copying, Adding, and Activating Packages”
section on page 6-22.
• Contact your system administrator for a flash disk containing the bootable .vm file.
• Contact your Cisco representative for a flash disk containing the bootable.vm file. See the
“Obtaining Technical Assistance” section on page xiv for more information.
Note The removable disk1: is used to store archives of .vm and .pie files only. This disk cannot be used as a
destination for installed software or configurations. Only the internal flash disk0: can be used to store
active software and configurations. See the “File Storage” section on page 1-11 for more information.
Prerequisites
A valid.vm image as described in the “Locating Installable Files” section on page A-12 must be located
on the removable flash disk (disk1:). The software can be installed only using a .vm file located on disk1:
or TFTP server.
SUMMARY STEPS
1. Back up the router configuration while still in EXEC mode.
2. Place both the standby RP and the primary RP in ROM monitor mode.
3. Prepare the standby RP:
a. unset BOOT
b. unset TFTP_FILE
c. EASYBAKE=0x100000000
d. sync
