Performing an ISSU for a single-chassis IRF fabric

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 and the value of the Upgrade Way field is Service Upgrade or File
Upgrade, the new and old images are compatible and an incremental upgrade is recommended.
To perform an incremental upgrade to a compatible version, execute the following commands in user
view:
Command
•
To complete the ISSU process, use
the following command to upgrade
the subordinate members that have
not been upgraded (including the
original master):
issu commit slot slot-number
•
To roll back to the original software
configuration:
issu rollback
Command
•
Method 1:
issu load file { boot filename | system
filename | feature
filename&<1-30> } * slot
slot-number&<1-9>
•
Method 2:
issu load file ipe ipe-filename slot
slot-number&<1-9>
•
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

Remarks
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
changes to Init.
During this ISSU process, you can use the
issu rollback command to roll back to the
original software configuration. For more
information about rollback, see
Fundamentals Command Reference.
Remarks
Specify the member IDs of the
subordinate members to be upgraded for
the slot slot-number&<1-9> option. If the
member devices of the IRF fabric are
connected into a ring topology, HP
recommends that you specify 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
changes to Init.
During this ISSU process, automatic
rollback is not supported, but you can
use the issu rollback command to
manually roll back to the original
software configuration. For more
information about rollback, see
Fundamentals Command Reference.
