Chapter 5 Maintenance and Service 5-15

■ In the RSM tray: the SEN card and the WD2S card

Install a jumper at location ID3 to change SCSI address range from 0-7 to 8-15.

■ The entire disk tray

RAID Manager 6 Recovery Guru reports drive side channel failure when the failure

affects the entire disk tray. After the hardware component has been replaced, run a

health check to verify the status of the drive channel, drive tray, and each disk drive.

You might need to power cycle the controller module (not the entire rack), even

though RAID Manager 6 Recover Guru instructions indicate that you don’t have to

power cycle the controller module if the controller firmware level is 2.5.2 or higher.

You need to power cycle the controller module if any of the following conditions

occur:

■ The LUN reconstruction does not start.

Note – LUN reconstructions occur one at a time serially per controller.

■ Health check continues to report drive side channel failure.

■ Any of the drives in the disk tray do not come out of the failed or unresponsive

state to reconstruct.

Power cycling of the controller module enables the controller to re-scan the disk

trays. If you continue to encounter error messages while attempting to bring a drive

back online (reconstruct), physically remove the drive, wait 30 seconds, and then

reinstall the drive. Then use RAID Manager 6 Recovery Guru to reconstruct the

drive.

Note – Remember to replace any dummy drives that were removed during disk

tray service. The dummy drives are important to maintain proper air flow and

cooling in the disk tray.

5.2.12 Midplanes

See Section 6.3.3 in the Sun StorEdge A3500/A3500FC Controller Module Guide to

remove and replace the controller card cage with the midplane.
