HP 5800 Series Configuration Manual page 151

To configure compatible ISSU:
Step
1. Enter system view.
2. Upgrade the
specified
subordinate switch
(the new master
after the upgrade).
3. Reboot the master
current manually.
4. Accept the ISSU.
5. Upgrade an IRF
member switch that
has not been
upgraded.
Command Remarks
system-view —
Required
slot-number is the member ID of the subordinate switch.
issu load file
upgrading-filena
The specified subordinate switch reboots with the new boot file
me slot
when this command is executed.
slot-number
Perform the next operation after the subordinate switch is
rebooted.
Required
With this command executed:
•
The master reboots with the current boot file, and becomes
a subordinate switch after reboot.
•
The subordinate switches of the IRF virtual device perform
issu run
master election. The winner (the subordinate switch
switchover slot
specified with issu load) becomes the new master.
slot-number
IMPORTANT:
•
The slot-number provided in this command must be the
same as that specified in the issu load.
•
Perform the next operation after the reboot process is
completed.
Optional
By default, the rollback timer is 45 minutes. If you do not run
issu accept on the specified subordinate switch or you do not
run issu commit command on any other member switch before
the rollback timer expires, the system automatically stops the
ISSU process and reverts to the previous software version.
issu accept slot
slot-number
IMPORTANT:
•
The slot-number argument provided in this command must
be the same as that specified in the issu load.
•
When this command is executed, the rollback timer
becomes invalid, which means the boot file cannot be
automatically rolled back.
Required.
•
This command upgrades one IRF member switch at a time.
If the IRF virtual device has three or more than three member
switches, repeat this command to upgrade them one by
one.
issu commit slot
•
When all IRF member switches reboot with the new boot
slot-number
file, the ISSU process completes.
After executing issu commit, you cannot roll back the current
boot file version BB to former version AA. To do so, use the AA
version boot file as the new boot file version to perform another
ISSU for the IRF virtual device.
