HP Switch zl Modules
4. Perform Switchover
E8200zl#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 notan issue, use the boot system command. Both management
modules will then be running the new software version.
5. Both management modules are now updated to new software. If two step
update is required repeat steps 1 through 4 again installing next step
software.
Note: When a bootROM is updated with software after the boot standby command
is entered the switch will reboot twice, first to update the BootROM to new
version, and then to load the updated system software. Following file copy to
the switch flash and initiation of the boot standby command, no additional
user intervention is needed. Do not interrupt power to the switch during this
important update. See the release notes for additional information.
