Corrective Action

The nodes cannot
access the storage
system, or the cluster
software is not
functioning with the
storage system.

The storage system is
not cabled properly to
the nodes or the
cabling between the
storage components is
incorrect.

Ensure that the cables are connected
properly from the node to the storage
system. For more information, see
the Dell Failover Cluster Hardware
Installation and Troubleshooting
Guide for the specific storage array
on the Dell Support website at
support.dell.com.

One of the cables is
faulty.

Replace the faulty cable.

You are using iSCSI
storage array, the
challenge handshake
authentication
protocol (CHAP)
password entered is
wrong.

Enter correct user-name and
password for CHAP, if used.

You are using a Dell™
PowerVault™
MD3000 or
PowerVault MD3000i
storage array and the
Host Group or Host-
to Virtual Disk
Mappings is not
correctly created.

Verify the following:

• Host Group is created and the

cluster nodes are added to the Host
Group.

• Host-to-Virtual Disk Mapping is

created and the virtual disks are
assigned to the Host Group
containing the cluster nodes.
