Presenting LUNs to a Netvault Proxy (Windows system) using the Nutanix Plugin
说明
In order for the NetVault Proxy to backup the VMs disks, the LUNs must be correctly presented to the system. Furthermore, the disks could remain attached to the proxy at the end of the backup process if the Windows system automatically mount the disk and detect failures on the file system.
原因
When a disk is automounted in Windows and there is an error detected on the file system, chkdsk will start a diagnostic on the drive. If the scan is incomplete, the command to dismount the disk will be overdriven by the running process and remain attached.
解决办法
On the NetVault proxy, ensure that the "automount disable" and "automount scrub" commands have been run to disable automatic drive letter assignment. The automount scrub command will clean any registry entries pertaining to previously mounted volumes.
Open a command prompt with admin rights
Type diskpart
At the prompt, type automount disable
The system should display "Automatic mounting of new volumes disabled."
At the prompt, type automount scrub
The system should display "DiskPart successfully scrubbed the mount point settings in the system."
Type exit
Optionally, confirm that the following dword registry key is set to 1 (enable)
As a result of the “automount disable” and “automount scrub” commands having been run, the LUN’s should appear in Windows Disk Administrator as “unknown”. Do not attempt to mount, partition, or format these disks.
Sometimes it may not show as "Unknown", but they will have NO drive letter assigned.
