Troubleshooting
T
his chapter provides general troubleshooting informa-
tion for the Dell PowerEdge Cluster. For troubleshooting
information that is specific to the Windows NT Server
Enterprise Edition operating system and the cluster soft-
ware, refer to the Microsoft Windows NT Cluster Server
Administrator’s Guide.

The cluster server nodes cannot
access the Dell PowerEdge Scal-
able Disk System 100 (SDS 100)
storage system, or the cluster
software is not functioning with
the storage system.
The SDS 100 storage system
has not been upgraded with
the cluster-specific firm-
ware.
The PowerEdge Expand-
able RAID Controllers have
the same small computer
system interface (SCSI) ID.
Ensure that the system management bus
(SMB)-connected node on the cluster is running
the cluster-specific firmware. Upgrade the SDS
100 firmware by powering down the cluster and
then starting it up again. During start-up, the
cluster-specific firmware on the node checks the
version of the SDS 100 firmware. If the SDS 100
is found to be running the wrong version of
firmware, the node proceeds to upgrade it auto-
matically with the correct firmware version.
Set the controller in the primary node to SCSI ID
7, and set the controller in the secondary node to
SCSI ID 10. Refer to Chapter 3 for instructions
for setting the SCSI IDs on the nodes.
System management of the
shared storage subsystem(s) is
not available when the SMB-
connected node fails.
The SMB connection is lost
when the SMB-connected
node fails and needs to be
reestablished with the sec-
ondary node.
Disconnect the SMB cable from the failed node
and connect it to the secondary node. Run the
cluster rediscovery application in LANDesk so
that the fail-over system scans the hard-disk
drives on the shared storage subsystem(s) and
reestablishes system management of the drives.
Refer to Chapter 4 for information on running the
rediscovery application.
