I have a new OES11SP1 cluster serving storage volumes from an external fibre channel device. The cluster itself is functioning correctly but I am struggling to get a backup working (with Syncsort Backup Express). A Syncsort engineer identified that the cluster is not advertising the clustered resources as it should. If I run:

# tsatest --cluster -s STORAGE-VOL1-SERVER -v VOL1: -u root --err output.log

I get this error message:

Failed to get name space type information: fffdffc5

The same error occurs on VOL2 and VOL3 from the cluster. However I can access the volumes via the individual cluster nodes in Backup Express so if necessary I'll have to backup that way.

At this point I'm stuck as I can find no other reference to this message. Can anyone give me a nudge in the right direction to start investigating this?
