Can not completely delete a Metaset

Question

we are configuring a Solairs Cluster 3.2, and someone deleted a metaset incorrectly, now we have the follwoing situation:
metaset does not show it
cldg shows it
it is still in the ccr
it can not be deleted or purged (with metaset -P or -C purge)
it can not be recreated
root@NodeA # metaset  -s metaset01
metaset: NodeA: setname "metaset01": no such set
## Repeeated on NodeB, same result
root@NodeA # cldg show metaset01
=== Device Groups ===
Device Group Name:                              metaset01
  Type:                                            SVM
  failback:                                        false
  Node List:                                       NodeA, NodeB
  preferenced:                                     true
  numsecondaries:                                  1
  diskset name:                                    metaset01
root@NodeA # metaset
Set name = metaset02, Set number = 2
Host                Owner
  NodeA
  NodeB
root@NodeA # metaset -s metaset01 -a -h NodeA NodeB
sc_rval = 2
metaset: NodeA: setname "metaset01": no such setAny idea on how to purge this metaset out of the ccr?

If this is a production cluster, please call Sun support. If it was installed by them, you should have the SUNWscdtk package installed which should allow you to remove it using dcs_config (I think).
If it is just a cluster to play with (i.e. dev, test... basically unimportant if you mess it up), then you could 'hack' the ccr and remove the offending metaset. You'd need to boot the nodes in non-cluster mode (-x) and then go to the /etc/cluster/ccr directory and find all files with reference to the set. Some will just need a line removing (directory, IIRC), others will need to be removed completely (dcs_XXX). You will need to rechecksum these files using 'ccradm -i <file> -o' then boot into cluster mode again.
I would recommend backing up the /etc/cluster/ccr directory just in case it all goes pear shaped!
Remember, this is just for non-production clusters.
