Troubleshooting Array and Expansion Enclosure Connections

1Verify that the RAID controller module port link status LED and the RAID controller module status LED are solid green for each port that is connected to a cable. If the LEDs are not solid green, see "Planning: RAID Controller Modules" on page 31.

2Ensure that all the cables are attached correctly according to array mode you selected.

3Turn off the server, storage array, and expansion enclosures.

4Reseat the RAID controller module and reconnect cables on the storage array and the server.

5Turn on the expansion arrays and then the storage array and wait until the system is fully booted.

6Turn on the server.

7Check the link status LED. If the link status LED is not green, replace the cables.

If the problem is not resolved, see "Getting Help" on page 265.

8Reboot the host server.

NOTE: You must turn off the host server before resetting the cables on the storage array or expansion enclosure.

If the problem is not resolved, see "Getting Help" on page 265.
