b. Locate the controller shelf, which is marked with the controller icon .
c. Click the controller icon.
d. Select the controller, and click Next.
e. On the Base tab, make a note of the Replacement Part Number for the controller.
Step 4. Confirm that the replacement part number for the failed controller is the same as the FRU part
number for the replacement controller.
Attention: Possible loss of data access – If the two part numbers are not the same, do not
attempt this procedure. In addition, if the failed controller canister includes a host interface card
(HIC), you must install that HIC into the new controller canister. The presence of mismatched
controllers or HICs will cause the new controller to lock down when you bring it online.
Step 5. Back up the storage array's configuration database.
If a problem occurs when you remove a controller, you can use the saved file to restore your
configuration.
a. Open the Enterprise Management Window (EMW) for ThinkSystem Storage Manager on your
management station.
b. Select the storage array.
c. Select Tools ➙ Execute Script.
d. Type the following command in the text box.
save storageArray dbmDatabase sourceLocation=onboard contentType=all file="filename";
In this command, filename is the file path and file name to which you want to save the
database. Enclose the file name in double quotation marks (" "). For example:
file="C:\Program Files\CLI\logs\dbmdata.zip"
This command does not automatically append a file extension to the saved file. You must
specify a file extension when entering the file name.
e. Select Tools ➙ Verify and Execute.
Note: If you have an untrusted certificate, you may need to accept the Security Exception.
Step 6. Collect support data for your storage array using ThinkSystem System Manager.
1. Select Support ➙ Support Center ➙ Diagnostics.
2. Select Collect Support Data.
3. Click Collect.
The file is saved in the Downloads folder for your browser with the name support-data.7z.
Step 7. If the controller is not already offline, take it offline now using either ThinkSystem System Manager
or the Enterprise Management Window's (EMW) script editor of ThinkSystem Storage Manager.
• To use ThinkSystem System Manager:
1. Select Hardware.
2. If the graphic shows the drives, select Show back of shelf to show the controllers.
3. Select the controller that you want to place offline.
4. From the context menu, select Place offline, and confirm that you want to perform the
operation.
