6.3.1.1 Configuration and boot-env Synchronization
Configuration and boot-env synchronization are supported in the
admin>redundancy>synchronize and config>redundancy>synchronize
contexts.
6.3.1.2 State Database Synchronization
If a new standby CPM or CFM is inserted into the system, it synchronizes with the
active CPM or CFM upon a successful boot process.
If the standby CPM or CFM is rebooted, it synchronizes with the active CPM or CFM
after a successful boot process.
When configuration or state changes occur, an incremental synchronization is
conducted from the active CPM or CFM to the standby CPM or CFM.
If the synchronization fails, the standby CPM or CFM does not reboot automatically.
Use the show redundancy synchronization command to display synchronization
output information.
If the active and standby CPMs or CFMs are not synchronized for any reason, you
can manually synchronize the standby CPM or CFM by rebooting the standby by
issuing the admin reboot standby command on the active or the standby CPM or
CFM.
6.4 Synchronization and Redundancy
The 7210 SAS-R6 and 7210 SAS-R12, and the 7210 SAS-Sx/S 1/10GE configured
in the standalone-VC mode support CPM redundancy. Redundancy methods
facilitate system synchronization between the active and standby CPMs so they
maintain identical operational parameters, which prevents inconsistencies in the
event of a CPM failure.
When automatic system synchronization is enabled for an entity, save or delete file
operations that are configured on the primary, secondary or tertiary choices on the
active CPM file system are mirrored in the standby CPM file system.
Although software configurations and images can be copied or downloaded from
remote locations, synchronization can only occur locally between compact flash
drives (cf1: and cf2:).
