Chapter5 Redundancy and SONET APS Configuration
NSP Redundancy
Troubleshooting and Monitoring PCMCIA Disk Mirroring
Use the show redundancy sync-status EXEC command to display all status information on disk
mirroring and synchronization.
Use the debug disk-mirror EXEC command to display debug messages for IFS call events, disk write
events, and disk synchronization events.
Using NSP Redundancy for Hardware Backup
For simple hardware backup, the redundant NSPs must have the same system image.To ensure that the
redundant NSPs run the same image, complete the following steps:
Step 1 Use the show bootvar EXEC command to display the current booting parameters for the primary and
secondary NSPs. Check that the secondary NSP is up.
Switch# show bootvar
BOOT variable =
CONFIG_FILE variable =
Current CONFIG_FILE variable =
BOOTLDR variable does not exist
Configuration register is 0x0
Secondary is up.
Secondary BOOT variable =
Secondary CONFIG_FILE variable =
Secondary BOOTLDR variable does not exist
Secondary Configuration register is 0x0
Step 2 Use the dir {bootflash: | disk0: | disk1: | sec-bootflash: | sec-disk0: | sec-disk1:} EXEC command to
verify the location and version of the primary and secondary NSP software image.
Switch# dir disk0:
Directory of disk0:/
3 -rw- 628539 Jan 01 2000 00:08:55 c6400s-wp-mz.120-5.DB
109760827 bytes total (108228293 bytes free)
Switch# dir sec-disk0:
Directory of sec-disk0:/
8 -rw- 628224 Jul 01 1999 00:08:55 c6400s-wp-mz.120-4.DB
109760512 bytes total (108228608 bytes free)
Step 3 If the primary and secondary NSPs contain the same image version in the same location, the NSPs are
already configured for hardware backup. Do not proceed to the next step.
Step 4 If the secondary NSP does not contain the same image in the same location, use the delete and squeeze
EXEC commands to delete the secondary NSP software image.
Switch# delete sec-disk0:c6400s-wp-mz.120-4.DB
Switch# squeeze sec-disk0:
Step 5 Copy the primary NSP image to the same location on the secondary NSP.
Switch# copy disk0:c6400s-wp-mz.120-5.DB sec-disk0:c6400s-wp-mz.120-5.DB
