I've got an ESXi 5.1 host running a SBS 2011 guest OS. I need to increase the size of one of the virtual disks in that OS. I've powered down, logged in as a user with admin rights to the client, but the functionality to increase the disk size is greyed out.
The name of the VMDK is servername-000001.vmdk, so I assume a snapshot is involved? I've checked the snapshot manager and there is a snapshot for Veeam (which I do use for backup).
I didn't want to go any further and possibly cause problems with the backup by deleting the Veeam snapshot.
Am I on the right track here? Suggestions?
