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 ensure 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 configuration is valid. See the SAS hardware documentation for valid cable configurations. If the cable configuration is invalid, you may receive alerts 2182 or 2356.

For information about alert messages, see the Dell OpenMnage Message Reference Guide.
