I've justed spend 1 hour to figure out why after upgrading with
red-carper from OES linux SP1 -> SP2 the CLUSTER SERVICE (NCS) is not

1st. after patching the server as TID, make sure to back to red-carpet
and install the additionnal patch for kernel modules .

2nd. seems like now we have _admin AND admin volume
why ? don't know.
Seems that someone made a typo, but whatever.
I had to change /opt/novell/ncs/bin/ClusterCliUtils.pm AND
/opt/novell/ncs/bin/ClusterCliSnapinInterface.pm and replace all _admin
with admin.
Voila !
Novell, please correct this....
