Upgrading Failover Pairs
Step 3
Make both failover groups active on the primary unit by entering the following command in the system
execution space of the primary unit:
primary# failover active
Step 4 Reload the secondary unit to boot the new image by entering the following command in the system
execution space of the primary unit:
primary# failover reload-standby
Step 5
When the secondary unit has finished reloading, and both failover groups are in the Standby Ready state
on that unit, make both failover groups active on the secondary unit using the following command in the
system execution space of the primary unit:
primary# no failover active
Note
Use the show failover command to verify that both failover groups are in the Standby Ready
state on the secondary unit.
Step 6
Make sure both failover groups are in the Standby Ready state on the primary unit, and then reload the
primary unit using the following command:
primary# reload
If the failover groups are configured with the preempt command, they will automatically become active
on their designated unit after the preempt delay has passed. If the failover groups are not configured with
the
preempt command, you can return them to active status on their designated units using the failover
active group command.
Upgrading Failover Pairs to a New Minor or Major Release
To upgrade two units in an Active/Active or Active/Standby failover configuration to a new minor or
major release, perform the following steps.
Step 1
Download the new software to both units. See the “Installing Application Software from the FWSM
CLI” section on page 24-3 .
Step 2 Ensure that the secondary unit has a configuration saved to memory by entering the following command:
secondary(config)# write memory
The saved configuration will load when you restart the secondary unit. This step is useful if the primary
unit fails to start up correctly.
In multiple context mode, enter the write memory all command from the system execution space. This
command saves all context configurations to which the FWSM has write access.
Step 3
To load the new software, reload the primary unit and then reload the secondary unit before the primary
unit comes online. Enter the following command separately on each unit:
primary(config)# reload
Proceed with reload? [confirm]
At the “Proceed with reload?” prompt, press Enter to confirm the command.
