Before you begin
• Your storage array must have two controllers. The controller that you are not placing offline must be online
(in the optimal state).
• You have verified that no volumes are in use or that you have a multipath driver installed on all hosts
using these volumes.
About this task
Perform this task only if your storage array has two controllers (duplex configuration).
Procedure
1. From SANtricity System Manager, review the details in the Recovery Guru to confirm that there is an issue
with a battery and to ensure no other items must be addressed first.
2. From the Details area of the Recovery Guru, determine which battery to replace.
3. 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 SANtricity System 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.
4. Collect support data for your storage array using SANtricity System Manager.
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 either SANtricity System Manager or the
Enterprise Management Window's (EMW) script editor:

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.
