Information in this document applies to any platform.

Symptoms

Critical Faults of:

Common Array Manager alarm code xx.66.1091: Battery Tray.xx.Battery.x has transitioned to an unknown state
SANtricity Storage Manager fault of BATTERY_UNKNOWN_STAT

Reference: <Document 1021057.1> Sun Storage Common Array Manager (CAM): How to Verify Critical Faults for Sun Storage 2500, 2500-M2, 6000 and J4000 Arrays

Cause

A possible controller offline/failure has caused a problem in getting the battery status, or, possibly, a failure in the cache battery handling system of the array has lost track of the battery status.

Solution

1. Verify the Critical Faults on the system and make sure that there is a critical fault for one or both batteries as follows.

Reference: <Document 1021057.1> Sun Storage Common Array Manager (CAM): How to Verify Critical Faults for Sun Storage 2500, 2500-M2, 6000 and J4000 Arrays.

Common Array Manager alarm code xx.66.1091: Battery Tray.xx.Battery.x has transitioned to an unknown state.
SANtricity Storage Manager fault of BATTERY_UNKNOWN_STAT.

If the faults are listed, continue to Step 2.
Otherwise, reference:

<Document 1021054.1> Troubleshooting Sun Storage[TM] Array SMART Battery Faults

<Document 1392919.1> Troubleshooting Sun Storage[TM] Array non-SMART Battery Faults

2. Verify Critical Fault List for a Controller Fault.

You have identified that your array is one that has a battery integrated or installed on the RAID controller of the system. If the RAID controller is transitioned to an offline state, the surviving controller will no longer be able to get the battery status. As such, the controller fault should be fixed prior to any work performed on the battery. If there are any of the following faults listed:

Common Array Manager alarm code xx.66.1028: Controller Tray.xx.Controller.x is offline.
Common Array Manager alarm code xx.66.1041: RPA Memory Error.
SANtricity Storage Manager fault for OFFLINE_CTL.
SANtricity Storage Manager fault for RPA_ERR_CTL.

you will need to resolve the controller issue prior to addressing the battery status.

Reference: <Document 1021113.1> Sun Storage 2500, 2500-M2, 6000 and Flexline Arrays: Troubleshooting RAID Controller Failures.

If none of the faults for controllers exist, continue to Step 3.

3. Verify AC Power Input has is not effecting Cache and Battery status.

Reference <Document 1398972.1> Write Cache Disabled on SunStorageTek 6540 Arrays After Loosing One AC Power Input

4. Verify Array Model and Remove and Insert the Battery then Check the status.

Reference <Document 1021066.1> Verify Sun Storage[TM] Array Array Type via the User Interface.

The batteries for a 6130 array are not customer replaceable and require an Oracle Service person to replace or reseat.

The batteries in these arrays are customer replaceable and hot pluggable:

6140
6180
Flexline 380
6540
6580
6780

You can remove and reseat these batteries without any impact to host data access. The write caching that the batteries protect has already been disabled by the fault(s) in the symptoms list.

The batteries in these arrays are customer replaceable but also require that the controller be offlined and removed to access the battery. In order to do this on an active system, you must have a dual controller configuration and a multipathing environment configured to allow the IO access through the surviving controller. Single controller arrays (some 2510/2530/2540 models) require an outage as there is no redundant path.

2510
2530
2540
2530-M2
2540-M2

Note: Follow carefully the instructions in Service Advisor, under Battery Removal and Replacement procedures. Depending on the model you may require a static mat and screwdriver to remove the battery, as is the case with any 2500 array. The 2500-M2 arrays also require an air blocker to be inserted in the vacated controller slot to properly cool the array while the controller is removed.

a) Remove the battery listed in the fault. Battery A or Battery 1 is on the left. Battery B or Battery 2 is on the right. Diagrams of the battery is located in the Service Advisor procedure for Battery Removal and Replacement in Common Array Manager.

b) Wait about 1-2 minutes then insert back the battery.

c) Wait about 5 minutes, then evaluate the list of faults again.

If this step has been completed without change, contact support for further troubleshooting.
If the array is not in the list of customer replaceable batteries, contact support for further troubleshooting.
