My vm backup server on ESXi will not power on after a catastrophic failure.

I tried to take a quick backup yesterday evening on Veeam of the exchange server published after a restore yesterday morning.
While the backup was in progress it suffered a failure and won't restart.
Tried to re-scan the datastore and remove the inventory and re-added the vm from the datastore but no joy

I can see the vm files in the datastore but on power up
The error message

Unable to access file [] /vmfs/volume >>>>>

can you check in vm configuration disks attached, order of the disk.

You could also try to boot on a cd windows rescue, to see what is going on.

and may be boot order of the bios

Hi Louis
Thanks for the quick response How do i boot from a cd windows rescue ?

The Unable to access file is point to a .vmdk that is not related to the server back server but the exchange server
I am so confused now

I don't actually see all the folder contents with the VMDK.

But that VMDK has a snapshot attached, please check the Disk3 exists on the datastore.

Do you have a backup?

Author

Commented:
That all the contained in the folder
Disk3 does not exist on the datastore and no backup ;-(
And sorry am newbie to the ESXi.

The file descriptor can be re-created on the ESXi server.

BUT is it the file descriptor which is missing ?

before I can advise, I really need to see a screenshot of the folder contents, because you've also got a snapshot.

Okay, there seems to be some weird things here....

because you have a server disk called

LWSRV09

and the disks are

LWSRV012

????

Also Disk 2 and Disk 3 appear to be missing.


Now this would also occur if a Datastore was MISSING from the ESXi host.,

There is a datastore which starts

d2.....

which I'm not seeing as listed....

Has the host restarted, crashed or anything ?

Okay, assuming this VM is called...

LWSRV09

for some strange reasons it's disks are called...

LWSRV012.

BUT...

won't I don't understand is there is NO LWSRV012 folder.....which the disk points to....

there is a LWSRV09 folder which contains two disks

and this contains two files

LWSRV09.vmdk - approx 50GB
LWSRV09_1.vmdk approx 7TB

So can you explain....

are these a backup ? and not the VM...

I think to understand, I really need to know WHAT HAPPENED form the Start!
