Problem
Unable to use Microsoft iSCSI Initiator
to connect to the PS Series array(s)
from the second node and the
following error message is displayed:
Authorization Failure.
The disks on the shared cluster
storage are unreadable or
uninitialized in Windows Disk
Administration.
Cluster Services does not operate
correctly on a cluster running
Windows Server 2003 and with
Internet Firewall enabled.
Public network clients cannot access
the applications or services that are
provided by the cluster.
Probable Cause
One or more nodes may have the
Internet Connection Firewall enabled,
blocking RPC communications
between the nodes.
The Enable shared access to the
iSCSI target from multiple initiators
check box is not selected.
• This issue occurs if you stop
the Cluster Service.
• On systems running Windows
Server 2003, this issue occurs
if the cluster node does not
own the cluster disk.
The Windows Internet Connection
Firewall is enabled, which may
conflict with Cluster Services.
One or more nodes may have the
Internet Connection Firewall enabled,
blocking RPC communications
between the nodes.
Corrective Action
Configure the Internet Connection
Firewall to allow communications that
are required by the MSCS and the
clustered applications or services.
