The
issu load
command separates the upgraded subordinate device from the existing IRF fabric to
form a new IRF fabric. When you execute the
issu run switchover
command, the master in the old
IRF fabric reboots to join the new IRF fabric as a subordinate member.
Before you execute the
issu run switchover
command on the old master, make sure the new
master has finished synchronizing its configuration and status data with the old master. To examine
the synchronization progress, use the
display device
and
display system internal ha service-group
commands on the new IRF fabric. The synchronization is completed if the following conditions are
met:
•
All cards of the device are in
Normal
state.
•
The
Action
field of the
display system internal ha service-group
command is 0 for each service.
