Cables Attached Correctly

Verify that the power-supply cord and adapter cables are connected correctly. If the system is having trouble with read and write

operations to a particular virtual disk or non-RAID physical disk (for example, the system hangs), then make sure that the cables connected

to the corresponding enclosure or backplane are secure. If the problem persists, you may need to replace a cable.

On SAS controllers, verify that the cable conguration is valid. Refer to the SAS hardware documentation for valid cable congurations. If

the cable conguration is invalid, you may receive alerts 2182 or 2356.

For information on alert messages, see the Server Administrator Messages Reference Guide.
