Replace E5700 battery
You can replace a failed battery in an E5700 storage system.
About this task
Each E5700 controller canister includes a battery that preserves cached data if the AC power fails. If the
Recovery Guru in SANtricity System Manager reports either a Battery Failed status or a Battery Replacement
Required status, you must replace the affected battery.
Before you begin
• Verify that no volumes are in use or that you have a multipath driver installed on all hosts using these
volumes.
• Review
Requirements for E5700 battery replacement.
What you’ll need
• A replacement battery.
• An ESD wristband, or you have taken other antistatic precautions.
• Labels to identify each cable that is connected to the controller canister.
• A management station with a browser that can access SANtricity System Manager for the controller. (To
open the System Manager interface, point the browser to the controller’s domain name or IP address.)
Step 1: Place controller offline (duplex)
If you have a duplex configuration, place the affected controller offline so you can safely remove the failed
battery. The controller that you are not placing offline must be online (in the optimal state).
Perform this task only if your storage array has two controllers (duplex configuration).
Steps
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 using SANtricity System Manager.
If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.
The system will save the current state of the RAID configuration database, which includes all data for
volume groups and disk pools on the controller.
◦ From SANtricity System Manager:
a.
Select Support
› Support Center › Diagnostics.
b. Select Collect Configuration Data.
c. Click Collect.
The file is saved in the Downloads folder for your browser with the name, configurationData-
<arrayName>-<dateTime>.7z.
◦ Alternatively, you can back up the configuration database by using the following CLI command:
save storageArray dbmDatabase sourceLocation=onboard contentType=all
