How to remove cluster services from NW 6.5

I have a two node NW 6.5 cluster using a shared SCSI DAS running Cluster
Services version 1.80.4. One of the nodes has a hardware issue and I don't
plan to replace it so I want to permanently remove the cluster services and
just run one server attached to the pools and volumes. I want to break the
cluster and remove the second node? Is TID 3317095 the proper way of
removing the servers but leaving the pools and volumes?

No! That TID is extremely dangerous, I'll get it pulled ASAP.

Some steps in it are correct though, and some others are missing.

1,2,3,4 are ok, and need to be done.

Step 5 is the dangerous piece. It's ok to delete the SBD Partition, but
*ONLY* the SBD partition. The advice to delete the clustered pools and
partitions is of course nasty.

After removing the SBD partition, you also need to unshare the device in
NSSMU. That step is missing from the TID.

6 and 7 are ok too.

Do *NOT* delete anything (Steps 8,9,10). Cluster software is always
installed in NW6.5, and should *not* be deleted. Just no longer loading
it is enough.

After all this is done, and the server comes up clean on a reboot, you
possibly also have to redo the regular volume object in NSSMU, using
ALT-F8.

Thanks for warning me. Will there be another TID posted for this?

Not another one, no. I've amended that TID accordingly.
