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

Appendix B: Error and Event Log Messages 195
Singleton cluster unable to take control of SAN, because the
cluster that includes NN.NN.NN.NN currently controls the
SAN. Possibly this server has not been added to the cluster
or has been deleted from the cluster, or possibly a
networking failure or misconfiguration has partitioned this
server from the servers that control the SAN.
Check the cluster configuration and add the server if it is not currently a
member. Also check the network to ensure that the server can
communicate with the rest of the cluster.
Singleton cluster unable to take control of SAN. Possibly
this server has not been added to the cluster or has been
deleted from the cluster, or possibly a network failure has
partitioned this server from the rest of the cluster. As a
result, some or all filesystem operations may be paused
throughout the cluster. In addition, filesystem mounts and
unmnounts and disk imports and deports cannot be performed.
Check the cluster configuration and add the server if it is not currently a
member. Also check the network connections and configuration for the
server to ensure that it can communicate with the rest of the cluster.
This monitor does not appear to be living on any particular
server. This is a UI bug.
If you receive this message, report it to HP Technical Support at your
earliest opportunity.
