Swapping the disks (for example RAID 5 to RAID 1) using ClusterRecovery.exe Tool

  • Artikel

In this exercise we are assuming that we have a SQL cluster with physical drive as R:. This drive currently holds all SQL related file (data file, log file, ftdata etc). We added a new drive call S: and we want to move all the mapping (data and signature) from drive R: to S:.

Please see the detailed steps below to achieve this through clusterrecovery.exe :-

1.Create a new Physical Disk Resource S: through Windows Cluster Administrator and point it to new Windows S: drive.

2.Take the SQL server resource offline in the Cluster Administrator and copy the content of the drive R: to the S: drive.

3.Double click the clusterrecovery.exe and you will get the following screen as shown below. Enter the WINDOWS cluster name and select the option "Replace a physical disk resource" and click Next.

4.After you click next you will get the below screen. Select the old physical disk resource as R (which currently holds all SQL files) and the new physical disk resource as S  and click replace. This will swap the disk signature and will automatically add all the dependency.

7. Get SQL Server online and complete your testing.

NOTE - Don't delete the "R (lost)" resource till your testing is completed. Keep it in offline state.

8. Delete the Disk resource R(lost) after testing is done.
