Finishing a Rolling Upgrade

To manually finish an upgrade and continue rebooting nodes that were not rebooted, complete the following steps:

Determine which partition was booted for each node by entering the show slot detail command.

The include keyword can be used to simplify the output. In the following example, only one of the Stanby nodes (Slot-3) was rebooted and is running the newer software version:

# show slot detail | include "information|Image|State|ver:"
Slot-1 information:
     State:               Operational
     Current State:       MASTER
     Image Selected:      primary
     Image Booted:        secondary
     Primary ver:         31.3.1.22
     Secondary ver:       31.3.0.106
Slot-2 information:
     State:               Operational
     Current State:       BACKUP (In Sync)
     Image Selected:      primary
     Image Booted:        secondary
     Primary ver:         31.3.1.22
     Secondary ver:       31.3.0.106
Slot-3 information:
     State:               Operational
     Current State:       STANDBY
     Image Selected:      primary
     Image Booted:        primary
     Primary ver:         31.3.1.22
     Secondary ver:       31.3.0.106
Slot-4 information:
     State:               Operational
     Current State:       STANDBY
     Image Selected:      primary
     Image Booted:        secondary
     Primary ver:         31.3.1.22
     Secondary ver:       31.3.0.106

Reboot any Standby nodes running the old software version individually, ensuring that the rebooted node is operational before moving on to the next node.
When all the Standby nodes are running the new software version and the network has converged, reboot the Backup node and allow it to go back “In-Sync” with the Primary node.

Note
After each reboot, allow a few minutes for the network to converge before proceeding.
Failover control of the stack from the Primary node to the Backup node by entering the run failover command.

When all nodes are running the newer software version, the upgrade is finished. At this point, all nodes should have both their selected and booted partitions set to the partition that contains the newer software version.
