be disconnected.
3. Failover to standby CP
a. Start a telnet session on the active CP.
b. Enter the haShow command to verify that HA synchronization is complete. It will take a minute or
two for the standby CP to reboot and synchronize with the active CP.
If the CPs do not achieve synchronization, stop here; log in to the standby CP, and enter the
firmwareRestore command to restore your original firmware.
c. Enter the firmwareShow command to confirm that the primary partition of the standby CP
contains the new firmware.
d. Enter the haFailover command. The active CP will reboot and the telnet session will be
disconnected.
If there is an AP blade is present: At the point of the failover an auto-leveling process is
activated. Refer to
procedure" on page 156 for details about auto-leveling.
4. Verify failover
a. Start a telnet session on the active CP (which is the old standby CP).
b. Enter the haShow command to verify that the HA synchronization is complete. It will take a minute
or two for the standby CP (which is the old active CP) to reboot and synchronize with the active CP.
NOTE: If the CPs fail to synchronize, you can still proceed because the version being tested is already
present on the active CP, and subsequent steps will ensure that the standby CP is updated to the same
version as the active CP.
c. The test version of firmware is now running on the active CP (you can confirm this by entering the
firmwareShow command).
