Enclosure management
modules (EMMs) are
not installed.
Install EMMs.
The PERC RAID adapter
drivers are not installed in
your Microsoft
®
Windows
®
operating system.
Install the drivers. See the PERC RAID
adapter documentation for more
information.
The option to change the SCSI
IDs is not visible in the
PERC 3/DC BIOS.
Cluster mode is not enabled. Enabling cluster mode will permit you to
change the SCSI IDs.
One or more of the SCSI
controllers are not detected by
the system.
PERC RAID adapters hang
during boot.
The controllers for the
shared storage system have
the same SCSI ID as their
peer adapters in the other
system (that is, the same
SCSI ID as the controllers
connected to the other side
of the shared
storage system).
Change one of the controller SCSI IDs so
that the ID numbers do not conflict. Set
the controller in the primary node to
SCSI ID 7 (default), and set the
controller in the secondary node to SCSI
ID 6. See the PERC RAID adapter
documentation for more information
about setting SCSI host adapter IDs.
Array Manager and PERC
RAID adapter BIOS utility only
report 13 drives in
cluster mode.
Normal The SCSI ID limitations are imposed by
SCSI protocol. As a result of this
limitation, the last slot in the PowerVault
22xS storage system cannot be utilized in
cluster mode.
One of the nodes takes a long
time to join the cluster, or fails
to join the cluster.
The node-to-node network
has failed due to a cabling or
hardware failure.
Check the network cabling. Ensure that
the node-to-node interconnection and the
public network are connected to the
correct network adapters.
Long delays in node-to-node
communications may
be normal.
Verify that the nodes can communicate
with each other by running the ping
command from each node to the other
node. Try both the host name and IP
address when using the ping command.
One or more nodes may have
the Internet Connection
Firewall enabled, and the
RPC communication
between the nodes has been
inadvertently blocked.
Configure the Internet Connection
Firewall to allow communications that are
required by the cluster service and the
clustered applications or services. For
more information see KB883398 at
support.microsoft.com.
