Troubleshooting

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

You are using a
Dell|EMC storage
array and Access
control is not enabled
correctly.

Verify the following:

• EMC

®

Access Logix™ software is

enabled on the storage system.

• All logical unit numbers (LUNs)

and hosts are assigned to the proper
storage groups.

You are using a Fibre
Channel storage array
in a Storage Area
Network (SAN), and
one or more zones are
not configured
correctly.

Verify the following:

• Each zone contains only one

initiator (Fibre Channel
daughter card).

• Each zone contains the correct

initiator and the correct
storage port(s).

You are using a Fibre
Channel storage array
and the length of the
interface cables
exceeds the maximum
allowable length.

Ensure that the fibre optic cables do
not exceed 300 m (for multimode)
or 10 km (for single mode
switch-to-switch connections only).
