Hello All.
I am in a situation where I need to replace a SAN disk in windows 2003 SQL cluster with a another disk with larger size. I cannot go for an expansion of the drive.
here is my plan but since this was not tried, I would like to confirm that works fine or any issues as I have read lot about issues with the change in disk signatures
1. Assign new SAN disks to the nodes.
2. Bring up the disk on one of the nodes and assign the temporary drive letter
3. Take the SQL instance offline and Copy over the data from old disk to the newly added disk
4. Remove cluster dependencies and delete the old physical disk resource from cluster
5. Add the new disk as a physical disk resource to the SQL cluster group
6. Configure the dependencies
7. Bring the SQL instance online
Please do advise if there is any harm in switching over the disk as mentioned above.
Thanks in advance
