HP 12500 Configuration Manual page 127

Before upgrade, use the display version comp-matrix file { boot filename | system filename | feature
filename&<1-30> } * or the display version comp-matrix file ipe ipe-filename command to display the
compatibility between the new and old images and the upgrade methods to be used:
• If a new image is on the Version compatibility list, the new and old images are compatible.
If a new image is not on the Version compatibility list, the new and old images are incompatible.
•
To perform an ISSU for a compatible version, execute the following commands:
Step
1. Enter system view.
2. (Optional.) Display
automatic-rollback timer
information.
3. (Optional.) Set the
automatic rollback
timer.
4. Return to user view.
5. Upgrade subordinate
members and configure
the upgrade images as
the main startup
software images for the
subordinate members.
6. Perform a
master/subordinate
switchover.
7. (Optional.) Accept the
upgrade and delete the
automatic-rollback timer.
8. Complete the ISSU
process or roll back to
the original software
configuration.

Remarks
N/A
If you don't think the ISSU can be
finished before the timer expires, adjust
the timer.
By default, the automatic-rollback
interval is 45 minutes.
This timer is started when you execute the
issu run switchover command. If you do
not execute the issu accept or issu commit
command before this timer expires, the
system automatically rolls back to the
original software configuration.
N/A
Specify the member IDs of the
subordinate members to be upgraded for
the chassis chassis-number&<1-3>
option.
N/A
N/A
After using the issu commit command to
upgrade one subordinate member, you
must wait for the subordinate member to
restart up and join the IRF fabric before
upgrading another subordinate member.
After all members are upgraded, the
ISSU process ends and the ISSU status
transitions to Init.
During this ISSU process, you can use the
issu rollback command at any point to
roll back to the original software
configuration. For more information
about rollback, see Fundamentals
Command Reference.
