test 1node oes2 - linux - cluster
with san shared storage
with sbd

Everything works fine with original SLES10SP1 and OES2 installation media.
After online updating the cluster node and reboot the cluster says "This node is not a member of a cluster".
The problem is that the evms update 2.5.5-2454.5 resolves it dependencies be deleting novell-evms-plugins.
And without novell-evms-plugins no nwmgr for evms, no sbd partition and no cluster.
There is also no way by creating a new sbd with sbdutil, because no nwmgr no working sbd patition.

NOVELL: Could anyone of you explain me that !!
