Use to find and repair structural inconsistencies and damage in the DOS file
system in NVS on the primary SRP module.
If the router contains primary and redundant modules, only NVS on the primary
SRP module is scanned.
On the E120 and E320 routers only, you can use this command to check and
repair a second flash card installed as disk1. You can issue this command in
Boot mode for either flash card. In Privileged Exec mode, you can use the disk1
keyword to access the unmounted second flash card while the router is in an
operational state.
This command is available for disk1 in Privileged Exec mode only on SRP 320
modules. This command is not accepted for disk0 in Privileged Exec mode.
