The redundant array of inexpen- sive disks (RAID) drives in the SDS 100 storage system are not accessible by one of the cluster nodes, or the shared storage subsystem is not functioning properly with the cluster software.
The SCSI cables are loose or defective, or the cables exceed the maximum allow- able length of 4 meters (m).
The appropriate cluster- specific PowerEdge Expandable RAID Control- ler driver is not running on the system.
The RAID controllers con- nected to a single storage system are not configured consistently.
If the cluster has multiple SDS 100 storage systems, the cabling between the RAID controller and the storage systems is wrong.
The SCSI cable between the node and the shared storage subsystem is faulty or not connected.
Check the cable connections or replace the cable with a working cable. Ensure that the length of the cable does not exceed 4 m.
Install the RAID controller driver that came with your system or cluster upgrade kit. Refer to Appendix A for instructions on installing the RAID controller driver.
Ensure that the RAID configuration is identical between the RAID controllers connected to the storage system.
Be sure that the cables attached to the channel 0 connectors on the RAID controllers are connected to one storage system and the channel 1 RAID controller cables are connected to the other stor- age system.
Attach or replace the SCSI cable between the cluster node and the shared storage subsystem.
The SDS 100 is not running in 1 x 8 mode.

The Cluster Mode setting in the system configuration utility is incorrect for a clus- tered system.
Install the configuration file update for the system configuration utility that came with your system or cluster upgrade kit.
Enter the system configuration utility and change the Cluster Mode field to Enabled. The Cluster Mode setting tells the cluster node to download the cluster firmware to the SDS 100 storage sys- tem, which then sets the storage system in 1 x 8 mode. Refer to Appendix A for information on updating the system configuration utility.
