Aborting a remote restart operation
You can abort or cancel a remote restart operation of an AIX®, Linux, or IBM® i logical partition by using the Hardware Management Console (HMC) command-line interface.
To abort or cancel the remote restart operation of a logical partition, type the following
command from the HMC command line:
rrstartlpar -m <source managed system> -t <target manged system> -p <lpar name>
-ip <IP address> [-u <user ID>] -o cancel
After the cancel operation completes on the destination server, the remote restart status
on source server changes to Remote Restartable.
