Synchronizing Switches in a Stack

“CMM” synchronization refers to the process of copying all files in the /flash/working and /flash/ certified directories of the switch with the primary Chassis Management Module (CMM) role to the /flash/working and /flash/certified directories of all the other switches in the stack. (This includes the switch with the secondary CMM role and all the switches with an idle CMM role.)

This synchronization process ensures that these directories match exactly for all switches in the stack. Synchronization prevents any switch in the stack from assuming the primary role with incorrect or outdated software or configuration files.

Important. In order to have effective redundancy, switches in the stack must be synchronized at all times.

To synchronize the switches in the stack, enter the following command at the CLI prompt:

-> copy working certified flash-syncro

For more information on CMM synchronization and managing the /flash/working and /flash/certified directories, refer to the “Managing CMM Directory Content” chapter in the OmniSwitch 6624/6648 Switch Management Guide.

Restoring Switch Redundancy

Once the copy flash-synchrocommand has been issued, the switches in the stack will have the correct software, but will not have loaded it into the running directory until the stack is rebooted. To reboot the stack for synchronization, use the restore redundancy command, as shown:

-> restore redundancy

This command will cause each element in the stack to reload.

Note. Connectivity to the switch is interrupted when this command is executed.

It may not be expedient to reboot a stack immediately after synchronizing the elements in the stack. It is possible to cause a synchronization reboot at a future time by setting time parameters in conjuction with the restore redundancy command, using the in or at keywords.

To schedule a resynchronization of a stack in 3 hours and 3 minutes, you would enter:

-> restore redundancy in 3:03

To schedule a resynchronization of a stack for June 30 at 8:00pm, you would enter:

-> restore redundancy at 20:00 june 30

Note. Scheduled resynchronization times should be entered in military format (i.e., a twenty-four hour clock).

To cancel a scheduled resynchronization enter:

-> restore redundancy cancel
