Redundant DR Site Cluster Restore

Hello,
We are restoring our production SQL cluster to an isolated DR site. The
server and SAN hardware are the same, the domain is the same, all of the IP
addresses are the same because the network is isolated.
Typically, we back our production servers up to tape and restore them on top
of a vanilla OS using NetBackup for our Windows DR restores. This usually
works fine, but we are always required to remove the restored server to the
domain, add it to a workgroup, and re-add the server back to the domain to
get rid of the " The trust
relationship between this workstation and the primary domain failed" error.
I have restored the OS of both nodes of the cluster to servers in the DR
site. The cluster service obviously will not start because of the "trust
error" which can't be resolved until the server is removed from the domain
and re-added.
My question is, if I do this to a node in the server, what will happen to
the cluster service/quorum/etc after I remove it from the domain. I'm going
to readd it immediately, but I'm wondering if it will cause any issues or if
there are any precautions I need to take? Or will the cluster just come up
assuming no other changes have been made?
Just go in and take all of the resource groups offline. Then stop the
cluster service in the service control applet. Once that is done, get the
servers added back to the domain. Once added back in, start the cluster
service, connect to your cluster, and start up all other groups.
