4. Collect support data for your storage array using SANtricity System Manager.
If a problem occurs when you remove a controller, you can use the saved file to troubleshoot the issue. The
system will save inventory, status, and performance data about your storage array in a single file.
a.
Select Support
› Support Center › Diagnostics.
b. Select Collect Support Data.
c. Click Collect.
The file is saved in the Downloads folder for your browser with the name, support-data.7z.
5. If the controller is not already offline, take it offline now using SANtricity System Manager.
◦ From SANtricity System Manager:
a. Select Hardware.
b. If the graphic shows the drives, select Show back of shelf to show the controllers.
c. Select the controller that you want to place offline.
d. From the context menu, select Place offline, and confirm that you want to perform the operation.
If you are accessing SANtricity System Manager using the controller you are
attempting to take offline, a SANtricity System Manager Unavailable message is
displayed. Select Connect to an alternate network connection to automatically
access SANtricity System Manager using the other controller.
◦ Alternatively, you can take the controllers offline by using the following CLI commands:
For controller A:
set controller [a] availability=offline
For controller B: set controller [b] availability=offline
6. Wait for SANtricity System Manager to update the controller’s status to offline.
Do not begin any other operations until after the status has been updated.
Step 2: Remove controller canister
Before you can remove the failed battery, you must remove the controller canister.
Steps
1. Put on an ESD wristband or take other antistatic precautions.
2. Label each cable that is attached to the controller canister.
3. Disconnect all of the cables from the controller canister.
To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
4. If the host ports on the controller canister use SFP+ transceivers, leave them installed.
5. Confirm that the Cache Active LED on the back of the controller is off.
