Replace battery
Each 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.
Steps
1. Place controller offline (duplex) on page 7
Place the affected controller offline so you can safely remove the failed battery. You must back up
the configuration and collect support data first. Then, you can take the affected controller offline.
2. Remove failed battery on page 9
You must remove the failed battery so you can install a new one.
3. Install new battery on page 12
You install a new battery into the controller canister to replace the failed one.
4. Place controller online (duplex) on page 16
Place the controller online to confirm the storage array is working correctly. Then, you can collect
support data and resume operations.
Place controller offline (duplex)
If you have a duplex configuration, you must place the affected controller offline so you can safely
remove the failed battery. You must back up the configuration and collect support data first. Then,
you can take the affected controller offline.
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).
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.
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 Storage Manager on your
management station.
b. Select the storage array.
