Current environment as below.
2 x physical nodes running windows 2008 cluster with san disks and quorum disk, running application and SQL/Oracle database.
My domain admin accidentally delete both cluster node computer object and cluster admin user from AD, when domain admin aware on this, domain admin unjoin the both cluster node server from domain and rejoin back to domain, recreate the new AD user. Now the
problem is when try to perform failover of application and database it will failed and cluster group unable to bring up. It was giving many error message when online the resources group (permission errors, CNO error and etc). Currently i down one of the cluster
node (node02) and manually up the application and database run in on node01.
My plan is to perform full backup of server OS, SQL database, remove node, disk and application from cluster and force clean up the cluster. After his, unjoin and rejoin both nodes back to domain, reconfigure the cluster.
I'm not so sure what to do with SQL and SQL database? Do you have any idea what to do with SQL cluster? What to do with existing cluster SQL database before proceed on cluster clean up?
Do i need to remove SQL from node when perform cluster clean up or before unjoin domain ? Rerun the SQL/Oracle setup after rejoin the domain, after this restore the database?Anyone can share out the steps how to do fix this issue?
