Note. If a switch fails over to the secondary CMM, it is necessary to have a management interface connec-
tion to the secondary CMM (such as an Ethernet port or a console port).
Copying the Working Directory to the Certified Directory
Synchronizing the Primary and Secondary CMMs
At the same time that you copy the working directory to the certified directory, you can synchronize the
secondary CMM with the primary CMM. In the case of redundant CMMs, this ensures that the two
modules are booting from the same software.
To copy the working directory to the certified directory of the primary CMM and at the same time
synchronize the software of the primary and secondary CMM, use the following command:
-> copy working certified flash-synchro
Note. This command does not function if the switch is running from the certified directory. See “Where is
the Switch Running From?” on page 5-4 for an explanation.
The copy working certified command synchronizes all switches in a stack. This command is described in
detail in the OmniSwitch 6250/6450 CLI Reference Guide.
Note. When synchronizing the primary and secondary CMMs, it is important to remember that the
boot.params file and the switch date and time are not automatically synchronized. See the OmniSwitch
6250/6450 Getting Started Guide for information on the boot.params file, and Chapter 1, “Managing
System Files,” for information on setting the switch date and time. The date and time are synchronized
using the system time-and-date synchro command.
