Software Upgrade Quick Start (continued)
Enter the show ft group detail command in Exec mode to verify the state
of each appliance. Upgrade the ACE that has its Admin context in the
STANDBY_HOT state (ACE-2) first by entering the reload command in
Exec mode. After ACE-2 boots up, it may take a few minutes to reach the
STANDBY_HOT state again. Configuration synchronization is still enabled
and the connections through ACE-1 are still being replicated to ACE-2.
Do not add any more commands to the ACE-1 configuration. At this
Note
point in the upgrade procedure, any incremental commands that you
add to the ACE-1 configuration may not be properly synchronized
to the ACE-2 configuration.
host1/Admin# reload
This command will reboot the system
Save configurations for all the contexts. Save? [yes/no]: [yes]
Perform a graceful failover of all contexts from ACE-1 to ACE-2 by
entering the ft switchover all command in Exec mode on ACE-1. ACE-2
becomes the new active ACE and assumes mastership of all active
connections with no interruption to existing connections.
host1/Admin# ft switchover all
Upgrade ACE-1 by reloading it and verify that ACE-1 enters the
STANDBY_HOT state (may take several minutes) by entering the show ft
group detail command in Exec mode. Because both ACE-1 and ACE-2 are
running the same version of software now, configuration mode is enabled.
The configuration is synchronized from ACE 2 (currently active) to ACE-1.
If ACE-1 is configured with a higher priority and preempt is configured on
the FT group, ACE-1 reasserts mastership after it has received all
configuration and state information from ACE-2, making ACE-2 the new
standby. ACE-1 becomes the active ACE once again.
host1/Admin# reload
This command will reboot the system
Save configurations for all the contexts. Save? [yes/no]: [yes]
Enter the show ft group detail command to verify that ACE-1 is in the
ACTIVE state and ACE-2 is in the STANDBY_HOT state.
