6.4.2 Active and standby designations on 7210 SAS-Sx/S 1/10GE in standalone-VC
mode
On the 7210 SAS-Sx/S 1/10GE configured in the standalone-VC mode, the user must designate and
configure two nodes as CPM-IMM nodes. During boot up, one of the configured nodes assumes the active
CPM role and the other assumes the standby CPM role. Typically, the configured CPMA-IMM node is
favored to be the active CPM and the CPMB-IMM is favored to be the standby CPM. If only one CPM-IMM
node is configured, it becomes the active CPM.
To visually determine the active and standby designations, the Master LED on the faceplate is lit (steady)
to indicate the active designation. The Master LED on the standby CPM faceplate blinks to indicate the
standby designation.
Example
The following output sample shows two nodes configured as CPM-IMM nodes with one becoming the
active node and the other becoming the standby node.

When CPM B boots, it waits 60 seconds to detect an active CPM A. If CPM A does not respond after 60
seconds, CPM B assumes the role of the active node.
6.4.3 When the active CPM goes offline
When an active CPM goes offline (due to reboot, removal, or failure), the standby CPM takes control
without rebooting or initializing itself. It is assumed that the CPMs are synchronized, therefore, there is no
delay in operability. When the CPM that went offline boots and comes back online, it becomes the standby
CPM.
Example
The following console message is displayed when the active CPM goes offline and the standby CPM
assumes the active role:
Active CPM in Slot A has stopped
Slot B is now active CPM
