Performing An Issu For A Single-Member, Dual-Mpu Irf Fabric - HP 12500 Configuration Manual

To perform an ISSU for an incompatible version, execute the following commands in user view:
Step
1. Upgrade subordinate
members and
configure the
upgrade images as
the main startup
software images for
the subordinate
members.
2. Complete the ISSU
process or roll back to
the original software
configuration.

Performing an ISSU for a single-member, dual-MPU IRF fabric

For an IRF fabric that has a single member with two MPUs, ISSU should be performed as per MPU in two
steps: first upgrade the standby MPU, and then upgrade the active MPU.
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.
Command
•
Approach 1:
issu load file { boot filename |
system filename | feature
filename&<1-30> } * chassis
chassis-number&<1-3>
•
Approach 2:
issu load file ipe ipe-filename
chassis chassis-number&<1-3>
•
To complete the ISSU process,
perform a master/subordinate
switchover to upgrade all
unupgraded members:
issu run switchover
•
To roll back to the original software
configuration:
issu rollback
Command
system-view
display issu rollback-timer
120
Remarks
Specify the member IDs of the
subordinate members to be upgraded
for the chassis chassis-number&<1-3>
option. If the member devices of the IRF
fabric are connected into a ring
topology, HP recommends you specify
a half of the subordinate members for
this command to reduce service
interruption. Make sure the specified
subordinate members are physically
connected.
After all members are upgraded, the
ISSU process ends and the ISSU status
transitions to Init.
During this ISSU process, automatic
rollback is not supported, but you can
use the issu rollback command at any
point to manually roll back to the
original software configuration. For
more information about rollback, see
Fundamentals Command Reference.
Remarks
N/A
If you don't think the ISSU can be
finished before the timer expires,
adjust the timer.
