Note : This is a sub-set of <Document: 1011431.1> : "Troubleshooting the Sun StorEdge[TM] 33x0/351x StorEdge Arrays." The steps below will help verify and resolve problems isolated to a battery.

IF THE ARRAY IS CONFIGURED WITH ONE RAID CONTROLLER FOLLOW THESE STEPS

Note: For a single controller configuration, all I/O must be stopped before beginning the replacement procedure.

1. Verify with customer that all I/O to this RAID Array has been stopped.
2. Power off both PCU's on the RAID array.
3. Remove all serial and ethernet cables from the RAID controller.
4. Remove the RAID controller.
5. Replace the battery according to the instructions printed on top of the RAID controller.
6. Re-install the RAID controller.
7. Re-install all serial and ethernet cables to the RAID controller.
8. Power on both PCUs on the RAID array.

IF THE ARRAY IS CONFIGURED WITH TWO RAID CONTROLLERS FOLLOW THESE STEPS

1. Determine the status of each RAID controller before beginning:
   • If a RAID controller's status LED is solid amber, it is offline.
   • If a RAID controller's status LED is blinking green, it is the PRIMARY controller and it is online.
   • If a RAID controller's status LED is solid green, it is the SECONDARY controller and it is online.
   • If both RAID controller's status LEDs are solid green for more than 2 minutes both controllers are offline.
   • If one RAID controller's status LED is solid amber and the other's status LED is off then both RAID controllers are offline.
2. Assuming both array controllers are in normal status. Connect to the array console via the serial interface (tip -38400 /dev/ttya or ttyb) or telnet. Note if using serial interface you may need to do a CTRL-L to refresh screen.
3. Fail the TARGET RAID CONTROLLER:
   • From the Main Menu, select View and Edit Peripheral Devices->Set Peripheral Device Entry->Redundant Controller-Primary.
   • Select either Force Primary Controller Failure or Force Secondary Controller Failure; which ever is appropriate.
4. Verify the controller status LED on the TARGET RAID CONTROLLER is solid amber, and the other controller is acting like the primary(LED is blinking green).
5. Remove all serial and ethernet cables from the TARGET RAID CONTROLLER. If necessary, connect the serial cable to the remaining RAID controller.
6. Remove the TARGET RAID CONTROLLER.
7. Replace the battery according to the instructions printed on top of the RAID controller.
8. Re-install the TARGET RAID CONTROLLER.
9. Re-install all serial and ethernet cables to the TARGET RAID CONTROLLER.
10. Repeat steps 3-9 to replace battery in the other controller.
11. If no problems found during the course of this document please refer back to <Document: 1011431.1> : "Troubleshooting the Sun StorEdge[TM] 33x0/351x StorEdge Arrays."
