New VMFS Volumes Exposed to the VCB Proxy Requires Rescan (1001587)
When new LUNs with VMFS volumes are exposed to the VCB proxy, you might see one of the following errors:
- Error: Disk library failed (One LUN could not be opened)
- Vmount2.Vmount2Service: Cannot open disk file: Error : Disk library failed (Cannot access a SAN/iSCSI LUN backing this virtual disk. (Hint: If you are using vcbMounter you can use the option "-m ndb" to switch to network based disk access if this is what you want.)
The error occurs when the vmount2 service, which mounts the virtual machines for file-level backups, is unable to see the new LUNs. Any change in the SAN topology (for example, introducing a new VMFS partition) requires a SAN rescan and the stopping of vmount2.
From the command line, type:
net stop vmount2
Through the Windows Services and Applications option: Right click My Computer and select Manage. Then, expand Services and Applications and click Services to view the list of services installed on your system. Locate the VMware Virtual Mount Manager Extended service and right-click to Stop the service.
