After installing the new software to the active management module, wait a few minutes, and then
verify that the standby management module has been synchronized with the new software as well
(use the show flash command.) If the default flash for boot is set correctly, you can start the
standby management module on the new software by executing the boot standby command.
This does not interrupt current switch operations yet. After the standby management module has
rebooted and is ready for takeover in standby mode (you can verify this using the show
redundancy command.) you can now switch over to the management module running the newer
software with this command:
HP Switch# redundancy switchover
This causes a switchover to the management module that received the new software version, which
becomes the active management module. This method incurs the least amount of network downtime
for booting. If downtime is not an issue, use the boot system command. Both management
modules are then running the new software version.
Potential software version mismatches after downloading
When a new software version is downloaded to the active management module, it is immediately
copied to the corresponding flash (primary or secondary) in the standby management module,
unless redundancy has been disabled. If the standby management module is rebooted, it will be
running a different software version than the active management module. You can direct the standby
module to boot from the non-corresponding flash image that has a different software version during
the actual reboot process of the standby module when the prompt to select the Boot Profile appears,
as shown in Figure 270 (page 490).
