Managing Cmm Redundancy; Rebooting The Secondary Cmm - Alcatel-Lucent OmniSwitch AOS Release 7 Manual

Managing CMM Redundancy

Managing CMM Redundancy
The following section describe circumstances that the user should be aware of when managing the CMM
directory structure on a switch with redundant CMMs. It also includes descriptions of the CLI commands
designed to synchronize software between the primary and secondary CMMs.

Rebooting the Secondary CMM

You can specify a reboot of the secondary CMM by using the secondary keyword in conjunction with the
reload command. For example, to reboot the secondary CMM, enter the reload command as shown:
-> reload secondary
In this case, the primary CMM continues to run, while the secondary CMM reboots.
Scheduling a Reboot
It is possible to cause a reboot of the secondary CMM at a future time by setting time parameters in
conjunction with the reload command.
For example, to schedule a reboot of the secondary CMM in 8 hours and 15 minutes on the same day,
enter the following at the prompt:
-> reload secondary in 08:15
Cancelling a Scheduled Reboot
To cancel a scheduled reboot, use the cancel keyword. For example, to cancel the secondary reboot set
above, enter the following:
-> reload secondary cancel
Secondary CMM Fail Over
If the Primary CMM fails the switch will "fail over" to the secondary CMM. "Fail over" means the
secondary CMM takes the place of the primary CMM. This prevents the switch from ceasing functionality
during the boot process.
Synchronizing the primary and secondary CMMs is done using the
described in "Synchronizing the Primary and Secondary CMMs" on page
