Parameters
minutes
: Specifies the automatic rollback interval in minutes, in the range of 0 to 120. Setting it to 0
disables the automatic rollback function.
Usage guidelines
The system starts the automatic rollback timer
when it executes the
issu run switchover
command. If you
do not execute the
issu accept
or
issu commit
command before the timer expires, the system automatically
rolls back to the software versions before the ISSU.
Change to the automatic rollback interval does not take effect on the ongoing ISSU process. The current
remaining rollback time might be greater than the configured automatic rollback interval.
Examples
# Set the automatic rollback timer to 50 minutes.
<Sysname> system-view
[Sysname] issu rollback-timer 50

Usage guidelines
The
issu load
command splits the IRF fabric into two fabrics, with the upgraded member forming a new
fabric. The
issu run switchover
command reboots and upgrades the old IRF fabric. After startup, the old
fabric's member join the new IRF fabric as the subordinate member and the ISSU process ends.
To check the synchronization progress, use the
display device
and
display system internal ha
service-group
commands. The synchronization is completed if the following conditions are met:
•
All cards of the subordinate device are in normal state.
•
The
Action
field of the
display system internal ha service-group
command is 0 for each service.
