Failed Battery

What Caused the Problem?
The battery in the controller canister has failed or has reached its expiration date. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Caution
Do not perform these recovery steps if you have just turned on the Storage Subsystem or replaced a controller. During these two situations, the battery's self-test diagnostics take approximately 12 to 15 minutes to complete (depending on the controller type and whether the batteries were discharged). Until the diagnostic test is completed, you may see a Recovery Guru failure for a battery that is operational and fully charged.

Caution
Electrostatic charges can damage sensitive components. Use a grounding wrist strap or other anti-static precautions before removing or handling components.

Important Notes

Recovery Steps
1
If... Then...
Your Storage Subsystem has one controller or you are not running a host-based, multi-path driver software such as RDAC on all hosts connected to this Storage Subsystem
a
Stop all I/O to this Storage Subsystem.
b
Go to Step 2.
Your Storage Subsystem has two controllers and you are running a host-based, multi-path driver software such as RDAC on all hosts connected to this Storage Subsystem.
a
Highlight the controller containing the failed battery in the Physical View of the Subsystem Management Window.
b
Select Controller>>Change Mode>>Passive.
c
Select Yes in the Confirm Change To Passive Mode window.
d
Go to Step 2.
2 Remove the controller canister. Battery replacement may involve replacing the individual battery or the entire controller canister. Consult your hardware documentation for details.

Note: If the Storage Subsystem is Directly Managed (refer to the Network Management Type column in the Enterprise Management Window) and you will be inserting a new controller canister, you must update the DHCP/BOOTP server so that it will associate the new controller's hardware Ethernet address with the host name and IP address previously assigned to the controller before you go to step 3. To update the DHCP/BOOTP server, find the entry associated with the removed controller and replace its Ethernet address with the new controller's Ethernet address. The controller's Ethernet address is located on an Ethernet ID label on the controller canister in the form xx.xx.xx.xx. If you need more details, consult the installation guide.

3 Record the installation date (today's date) and the new replacement date (according to the battery's warranty) on the battery label located on the controller canister containing the new battery.
4 Insert the controller canister containing the new battery securely into place.
5 Select the Components button on the controller enclosure in the Physical View of the Subsystem Management Window; then, select the Reset button associated with the controller canister containing the new battery to set the battery age to zero.
