Migration of SQL Cluster 2008 on windows server 2008
- (One Physical Node and 1 Virtual)
- Also migrate the storage (LUNS) from old SAN to the new SAN (robocopy)
- 2 VMware farms (old and new) – completely independent
From your past experiences, Would below high level steps achieve this above objective
- Remove (evict) the physical node from the SQL Cluster
- There is a Cluster with only 1 node (virtual)
- Storage Vmotion the SQL Virtual node (vmdk) to the new VMware Farm
- Please note old storage is accessible by the new VMware farm
- Therefore the pass through LUNS for SQL clusters will still be visible the virtual node
- Create NEW pass though LUNS on the NEW STORAGE with a temporary drive letter
- Robocopy all the data (all volumes) from the exiting volumes to the new VOLUMES with temporary drive letter
- Once the robocopy has finished , do a cut over i.e. change the temporary drive letters to the production drives letters
- OPERATE SQL server
Questions.
- As the new pass through LUNS would have different disk signatures etc, will the SQL Cluster ‘BEHAVE’ only if the drive letters are the same and exactly the same data as OLD pass through LUNS
- Or will we have to add them to the cluster again somehow?
We are going to LAB this but if anyone has prior experiences , it would be good to have their view as well and if we make it work, I will post the steps of the LAB
ALSO would this be supported from MS perspective?
