IBM Complete Guide to DS3200 Storage Subsystem Controller Replacement

12.Make sure that all storage expansion enclosure connections with each other have been completed (see the dual-controller topologies in “DS3200 storage subsystem drive cabling topologies” on page 28); then, connect the SAS drive expansion cable from the right ESM in the last storage expansion enclosure in the chain to the drive expansion port on controller B of the DS3200.

13.Wait up to 5 to 10 minutes for the DS3000 Storage Manager software to report the drives and the redundant drive path.

14.Verify the state of the LEDs on the newly inserted controller. See “Controller LEDs” on page 53. You can also use the DS3000 Storage Manager Subsystem Management window to identify any new faults. Do any storage subsystems have a fault (Needs Attention) status?

vYes: Click Recovery Guru in the Subsystem Management window toolbar, and complete the recovery procedure. If the problem remains, contact your IBM technical-support representative.

vNo: Go to step 15.

15.Use the DS3000 Storage Manager software to print a new storage subsystem profile.

Replacing a controller

Use these instructions to replace a controller.

Attention: Make sure that both power-supply units are connected and powered-on and no amber LEDs are lit. Make sure that the power LEDs on both power-supply units are lit. If the status of either of the power-supply units is not Optimal, replace that power supply before you proceed with the controller replacement procedure.

To replace a controller in a DS3200, complete the following steps.

Attention:

vIf you are replacing a failed controller with a replacement controller from IBM Service, you will transfer the controller battery to the replacement controller. The replacement controller contains a 512 MB DIMM; if the capacity of the DIMM in the failed controller is larger than 512 MB, you will also transfer that DIMM to the replacement controller. Transfer the DIMM and battery exactly as described in this procedure; failure to remove and insert these items in the correct sequence can damage the DIMM.

vIn a single-controller DS3200, shut down the DS3200 before you remove the controller.

1.Read the safety information that begins on page xi and “Best practices guidelines” on page 6.

2.In a single-controller storage subsystem, shut down the storage subsystem (see “Turning off the storage subsystem” on page 55 for the correct sequence of steps); then, continue with step 4.

3.Use the DS3000 Storage Manager software to print a storage subsystem profile. Move logical drive ownership to the other controller. If the controller that you are replacing has failed but is still operating, move the failed controller to the Offline state.

Attention: Never remove a controller unless the service action allowed LED is lit. Doing so can result in a loss of data.

4.Locate the failed controller by checking the amber LEDs on the controllers in the storage subsystem.
