1. Upgrade subordinate
members and
configure the
upgrade images as
the main startup
software images for
the subordinate
members.
• Method 1:
issu load file { boot filename |
system filename | feature
filename&<1-30> } * chassis
chassis-number&<1-3>
• Method 2:
issu load file ipe ipe-filename
chassis chassis-number&<1-3>
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
half of the subordinate members for
this command to reduce service
disruption. Make sure the specified
subordinate members are physically
connected.
2. Complete the ISSU
process or roll back to
the original software
configuration.
• To complete the ISSU process,
perform a master/subordinate
switchover to upgrade all members
that have not been upgraded:
issu run switchover
• To roll back to the original software
configuration:
issu rollback
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.
Performing an ISSU for a dual-MPU single-chassis 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 as well as 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:

2. (Optional.) Set the
automatic rollback
timer.
issu rollback-timer minutes
By default, the automatic-rollback
interval is 45 minutes.
This timer starts 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.
