HP StorageWorks Clustered File System 3.2.1 Windows Storage Server Edition Administration Guide (February 2006)

Appendix B: Error and Event Log Messages 193
Cluster unable to take control of SAN, because the servers
are unable to write to a majority of the membership
partitions, possibly due to a SAN hardware failure or
misconfiguration and/or because some servers have been
excluded from the SAN. As a result, some or all filesystem
operations may be paused throughout the cluster. In
addition, filesystem mounts and unmounts and disk imports
and deports cannot be performed.
Check the cluster configuration and add the server if it is not currently a
member. Also ensure that the server can access the membership
partitions and has write access to them, and check for any SAN hardware
problems.

Verify that this message, not one of the previous messages, is displayed.
Also verify that the servers can access the membership partitions and
have write access to them, and that the servers can communicate with the
FibreChannel switch. If no problems are found, contact HP Technical
Support.
Membership partition XXXX is unwritable, possibly due to a
SAN or storage hardware failure. If other membership
partitions become inaccessible, HP Clustered File System’s
ability to recover from a server failure will be
compromised.
None of the servers in the cluster can write to the specified membership
partition. Ensure that the servers can access the membership partition
and that they have write access for it. If the partition is corrupt, another
alert will display the location of the partition. See “Manage Membership
Partitions with mprepair” on page 160 for corrective actions.
