Now, connect to the active unit (which is still running the old cOS Core version) with a CLI
console and issue the ha -deactivate command. This will cause the active unit to become inactive,
and the inactive to become active.
Device:/> ha -deactivate
HA Was: ACTIVE
HA going INACTIVE...
To check that the failover has completed successfully, an ha command can be issued again and
the text "INACTIVE" and "is ALIVE" should appear in the output.
D. Upgrade the newly inactive unit
When the failover is complete, upgrade the newly inactive unit with the new cOS Core version.
Just like step B, this is done in the normal way as though the unit were not part of a cluster.
E. Wait for resynchronization
Once the second software upgrade is complete, two units will automatically resynchronize and
the cluster will continue operation. The roles of active and inactive unit will have been reversed.
If it is desirable to make the active unit inactive, and the inactive unit active, the CLI command ha
-active can be used.
