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:).
Synchronization can occur:
automatically
Automatic synchronization is disabled by default. To enable automatic synchronization, run the config>redundancy>synchronize command with the boot-env parameter or the config parameter.
When the boot-env parameter is specified, the BOF, boot.ldr, configuration, and image files are automatically synchronized. When the config parameter is specified, only the configuration files are automatically synchronized.
Automatic synchronization also occurs whenever the BOF is modified and when an admin>save command is entered with no filename specified.
manually
To execute synchronization manually, run the admin>redundancy> synchronize command with the boot-env parameter or the config parameter.
When the boot-env parameter is specified, the BOF, boot.ldr, configuration, and image files are synchronized. When the config parameter is specified, only the configuration files are synchronized.
The following output is an example of information displayed during a manual synchronization of configuration files.
