Monitoring the Current Configuration
File Synchronization–Configuration files are not synchronized to the standby
SRP when the HA state changes to disabled and the status is restored when
the recovery window is complete.
HA–Enabling of HA is prevented (HA remains in disabled state) during the
recovery window and the state is restored after the recovery window is
complete.
Unified ISSU–If unified ISSU is in the idle state, the operation is disabled
until successful recovery or the recovery window is complete. The unified
ISSU process continues if it has started.
Auto-Recovery A message indicates whether the configuration files are
recoverable. If the files are recoverable, the auto-recovery process starts. If
the recovery is unsuccessful, configuration monitoring is turned off. You can
revert the SRP to the last-known good configuration on the standby SRP
using the srp switch force command. The standby SRP boots up using the
last indicated configuration using the boot conf command.
If the file system on the standby SRP is corrupt when HA is disabled and the
mode of the service check-config command has been set to auto-recover, auto,
or manual, the following changes occur:
File Synchronization–Configuration files do not synchronize and the
synchronization state does not restore until successful recovery of the
corrupted files or the recovery window is complete.
HA–Enabling of HA is prevented during recovery and the state is restored
on successful recovery.
Unified ISSU–If unified ISSU is in the idle state, the operation is disabled
until successful recovery or the recovery window is complete. The unified
ISSU process continues if it has started.
Auto-Recovery Monitoring of corrupt configuration stops and a message
indicating whether the files are recoverable appears. If the SRP is successfully
recovered, monitoring of corrupt configuration resumes. If recovery fails,
reload the standby SRP module using the reload standby-srp command and
re-initiate the flash system on the standby SRP.
If the file system on the standby SRP is corrupt when HA is enabled and the
mode of the service check-config command has been set to auto-recover, auto,
or manual, the following changes occur:
File Synchronization–Configuration files are not synchronized when the
HA state changes to disabled and the synchronization state is not restored
until the successful recovery of the corrupted files or the recovery window
is complete.
HA–HA is disabled during recovery and the state is restored on successful
recovery.
