Configure The Issu Version Rollback Timer - H3C S5500-HI Series Fundamentals Configuration Manual

CAUTION:
To upgrade system software of the IRF fabric through ISSU when the new and current system software
image versions are incompatible, make sure that the multi-active detection (MAD) function has been
configured for the IRF fabric. Otherwise, duplicate IRF fabrics will coexist after the new master (the slave
switch specified with the issu load command) is rebooted, causing network faults.

Remarks
—
Required
slot-number is the member ID of the slave switch.
After this command is executed, the specified slave
switch (the new master after the upgrade) reboots
with the new system software image, and stays in
the Recover state after reboot.
Perform the next operation after the reboot process
completes.
Required
The slot-number argument provided in this
command must be the same as that specified in the
issu load command.
When this command is executed, all the IRF
member switches except the specified slave switch
(the new master) are upgraded to the new version,
and the ISSU process completes after reboot.
Remarks
—
Optional
By default, the rollback timer is 45 minutes. If you
do not execute the issu accept or issu commit
command on the specified IRF member switch
before the specified rollback timer expires, the
system automatically stops the ISSU process and
reverts to the previous software version.
