Battery Missing

What Caused the Problem?

A battery has been removed or is not present in the storage subsystem. The battery may have been removed or not properly seated. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

 Caution: Electrostatic charges can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.

Important Notes

Recovery Steps

Refer to the 'Component requiring service' field in the Details area to determine which Recovery Steps you need to complete.

If... Then...
The component requiring service is the battery Go to "Recovery Steps for a Directly-Accessible Battery."
The component requiring service is the controller that contains the battery Go to "Recovery Steps for a Battery Inside a Controller."

Recovery Steps for a Directly-Accessible Battery

1 Check the storage subsystem for the presence of the affected battery.
If... Then...
The battery is present Remove the battery and check the connector for damaged or dirty connectors.

Go to step 2.

You removed the battery

 

Go to step 2.
2 Reinsert the original battery or a replacement battery securely into place and wait for the storage subsystem to detect and register the battery.

Notes:

  • The time it takes to fully charge the battery depends on the model of the battery and its current state. While it is charging, the battery will report a Charging status. Consult the appropriate hardware manual for your model.
  • If you insert a replacement battery that is SBD (Smart Battery Data)-capable (only applicable if the Smart battery field in the Details area is YES), then the battery will start an initial Learn Cycle once the battery is fully charged.  Depending on the model of your storage subsystem, write caching may not be reinstated until the initial Learn Cycle is complete.
3 Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative.

Recovery Steps for a Battery Inside a Controller

If... Then...
Your storage subsystem has one controller Go to "Procedure for Storage Subsystems with One Controller."
Your storage subsystem has two controllers Go to "Procedure for Storage Subsystems with Two Controllers."

Procedure for Storage Subsystems with One Controller

1 Stop all I/O from all hosts to this storage subsystem.  When the Cache Active LED on the controller is no longer active (up to 5 minutes), proceed to step 2.

 Caution: Risk of Data Loss. You must wait for the Cache Active LED to stop blinking to ensure that all cache has been written to the drives in the storage subsystem.

2 Click the Save As button in the Recovery Guru dialog to save the remaining steps to a file.  These steps may no longer be accessible from the Recovery Guru dialog after you complete step 3.
3 Remove the controller canister that contains the affected battery.
4 Check the controller canister for the presence of the affected battery.
If... Then...
The battery is present Remove the battery and check the connector for damaged or dirty connectors.

Reinsert the original battery or a replacement battery securely into place, and then go to step 5.

You removed the battery

 

Reinsert the original battery or a replacement battery securely into place, and then go to step 5.
5 Insert the controller canister securely into place.  After the controller appears in the Physical View of the AMW, go to step 6.

Notes:

  • The time it takes to fully charge the battery depends on the model of the battery and its current state. While it is charging, the battery will report a Charging status. Consult the appropriate hardware manual for your model.
  • If the battery is SBD-capable (the Smart battery field in the Details area is YES), then the battery will also start an initial Learn Cycle once the battery is fully charged.  Depending on the model of your storage subsystem, write caching may not be reinstated until the initial Learn Cycle is complete.
6 Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative.

Procedure for Storage Subsystems with Two Controllers

1 If there are any hosts connected to this storage subsystem that are NOT running a host-based, multi-path failover driver, stop I/O to the storage subsystem from each of these hosts.
2 Place the affected controller offline.
a Select the controller in the physical view of the Subsystem Management Window.
b Select Advanced >> Recovery >> Set Controller >> Offline.
c Complete the instructions in the dialog, then select Yes.
3 Click the Save As button in the Recovery Guru dialog to save the remaining steps to a file.  These steps may no longer be accessible from the Recovery Guru dialog after you complete step 4.
4 Click the Recheck button to rerun the Recovery Guru.

There should be an Offline Controller problem reported in the Summary area.

5 Follow the Offline Controller Recovery Steps, until you have removed the controller. After you have removed the controller, do not continue with the Offline Controller Recovery steps until you are instructed to do so later in this procedure.
6 Check the controller canister for the presence of the affected battery.
If... Then...
The battery is present Remove the battery and check the connector for damaged or dirty connectors.

Reinsert the original battery or a replacement battery securely into place, and then go to step 7.

You removed the battery

 

Reinsert the original battery or a replacement battery securely into place, and then go to step 7.
7 Complete the remaining Offline Controller Recovery Steps.

Notes:

  • The time it takes to fully charge the battery depends on the model of the battery and its current state. While it is charging, the battery will report a Charging status. Consult the appropriate hardware manual for your model.
  • If the battery is SBD-capable (the Smart battery field in the Details area is YES), then the battery will also start an initial Learn Cycle once the battery is fully charged.  Depending on the model of your storage subsystem, write caching may not be reinstated until the initial Learn Cycle is complete.
