3.5.1 Matrix Server Administration Guide

Appendix B: Error and Log File Messages 336

Membership partition XXXX is unwritable, possibly due to a

SAN or storage hardware failure. If other membership

partitions become inaccessible, Matrix Server’s ability

to recover from a server failure will be compromised.

None of the servers in the matrix 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 mxmpconf” on page 287 for corrective actions.

Membership Partitions are corrupt or inaccessible, preventing SAN

access

A majority of the membership partitions are either inaccessible or

corrupt. Matrix Server cannot allow access to the PSFS filesystems while

the Membership Partitions are in this state. To obtain more detailed

information about the state of each Membership Partition, use the

mxmpconf command.

If membership partitions are reported as not found or inaccessible, there

is a problem with accessing the disk devices; check your hardware

configuration. If membership partitions are reported as corrupt, then

mxmpconf can be used to repair them, as long as at least one membership

partition is reported to be in a good (OK) state. (See “Manage

Membership Partitions with mxmpconf” on page 287 for more

information.)

psdNpN on NN.NN.NN.NN is stalled on locks from NN.NN.NN.NN

A DLM lock request has been outstanding for a long period of time on the

specified server. Probably the server is severely overloaded or is

experiencing a resource shortage. As a last resort, reboot the server to

clear the problem.
