1. Log into the cluster through SSH or log in from any node in the cluster using a local console cable and a
laptop/console.
2. Turn off AutoSupport and indicate how long you expect the system to be off line:
system node autosupport invoke -node * -type all -messages "MAINT=8h Power
Maintenance"
3. Identify the SP/BMC address of all nodes:
system service-processor show -node * -fields address
4.
Exit the cluster shell:
exit
5. Log into SP/BMC over SSH using the IP address of any of the nodes listed in the output from the previous
step.
If your’re using a console/laptop, log into the controller using the same cluster administrator credentials.
Open an SSH session to every SP/BMC connection so that you can monitor progress.
