I had two node rac , version 11203 ,running on Redhat ver 5.5
Node2 , crashed beacuse of curroption in the Operating system.
We are about to format the entire server , install the linux server and reuse the server back to the cluster.
Please advice :
1) should i first deletenode from the cluster and then add the seconde node once again ?
2) should i add the node as 3rd node , and then delete the second node from the cluster ?
First You can remove the crashed node from cluster using running node than you may need to Install a cloned image of the operating system that matches the operating system on the other nodes in your cluster and Verify the installation
And follow these documents to add node
