After restore -> VMware VM disks gets renumbered

[cdesch]

Hi all,

following situation:
- VM with 8 vDisks spreaded up into 8 datastore
- each VMDK file has the same name in its datatore VM folder
-> so during backup veeam have to rename the VMDK files to backup them all togeteher into one backup container file

---> with the following result:
- VM "hard disk 0" was before on scsi 0:0 -> now after restore i.e. the scsi 0:0 disk got the name "hard disk 5"

So since, Veeam does not save the information which scsi device node has which name before the backup, the restore action re-numbers the "VM hard disk name". It is not a problem for the VM itself, but for admins they are used to that "hard disk 0" is equal to "scsi 0:0" and so on.

So does anybody know how to solve the behaviour ?

Thx, chris

I don't think this can be solved, Veeam B&R indeed doesn't keep information about disk names, they get into the backup file randomly, due to parallel processing, and might mix up upon restore (though keeping their original SCSI slots).

Yes, but it should be no big deal to store that Information before the backup happens ... only to illustrate with powershell (sorry, but the Output is in german language)

Code: Select all

$VM = get-vm -name "vm251"
PowerCLI C:\> Get-HardDisk -VM $VM | select Filename,Name

Filename                                       Name
--------                                           ----
[DS01] VM251/VM251.vmdk             Festplatte 1
[DS01] VM251/VM251_1.vmdk         Festplatte 2

Thx, chris
