RP/0/RP0/CPU0:router# show filesystem disk1:
Model: UNIGEN FLASH
Capacity: 8215201 Sectors, Total 4206182912 Bytes, (512 Bytes/sector
Disk Formatting
Format the 4GB flashdisk on standby RP disk1: by executing the following command
RP/0/RP0/CPU0:ios#format disk1: partition filesystem fat32 location 0/rp1/cpu0
The above command will create a partition of 3.5/0.5 between disk1 and disk1a
Note Executing this command will not cause the RP to reset
Verifying the Disk File System
Verify the filesytem is changed to FAT32 file system and desired 80% and 20% partition between disk1
and disk1a disks by executing the following command
RP/0/RP0/CPU0:ios#show media location 0/rp1/cpu0
Mountpoint FsType FsType Size State DrvrPid Mirror Flags
================================================================================
/disk1: FAT16 FAT32 3.4G Mounted 0032792 Enabled
/disk1a: FAT16 FAT32 0.5G Mounted 0032792
Setting Up Disk Mirroring
Mirror the primary disk0 and standby disk1 disks on Standby RP using the command
RP/0/RP0/CPU0: LOAD(config)#mirror location 0/rp1/cpu0 disk0:disk1:
Verify that mirroring is enabled by executing the following command
RP/0/RP0/CPU0:LOAD#show mirror location 0/rp1/cpu0
Swapping Mirrored Disks
After verifying that disk mirroring is successfully enabled in the previous section, swap disk0 with disk1
(insert 4GB disk in disk0 slot)
Verifying Standby RP Disk Upgrade
Verify that the Standby RP boots with the 4GB flashdisk as the primary disk(disk0) on the Standby RP.
