system node autosupport invoke -node * -type all -message "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.
6. Halt the 2 nodes located in the impaired chassis:
system node halt -node <node>,<node2> -skip-lif-migration-before-shutdown true
-ignore-quorum-warnings true -inhibit-takeover true
For clusters using SnapMirror synchronous operating in StrictSync mode: system node
halt -node <node>,<node2> -skip-lif-migration-before-shutdown true
-ignore-quorum-warnings true -inhibit-takeover true -ignore-strict
-sync-warnings true
7.
Enter y for each controller in the cluster when you see
Warning: Are you sure you want to halt
node "cluster <node-name> number"? {y|n}:
8. Wait for each controller to halt and display the LOADER prompt.
Move and replace hardware - AFF A70, AFF A90
Move the power supplies, hard drives, and controller module from the impaired chassis to
the new chassis, and swap out the impaired chassis with the new chassis of the same
model as the impaired chassis.
Step 1: Remove the controller module
You must remove the controller module from the chassis when you replace the controller module or replace a
component inside the controller module.
1. On the front of the chassis, use your thumbs to firmly push each drive in until you feel a positive stop. This
ensures that the drives are firmly seated against the chassis midplane.
