Hi Deepak,
So, it would best to take the instance down then we do expansion?
1. The vdisk was connected to SAN Storage, hence I'll do allocation via SAN Storage.
2. Once allocated Disk Management detected the allocated space e.g. 500GB.
3. Before I expand the volume on the disk, it's wise to bring the SAP Instance down?
4. Expand the volume
5. Start up SAP
6. End of job
correct steps?
