Veeam B&R v8 in a VM with iSCSI VMFS datatstore present for Direct SAN
Hi Guys,
I am just getting to grips with Veeam and setting up Direct SAN access. I have Veeam running in a VM on 2008r2 and my VMFS datastores are presented to the VM, automount has been disabled, the volumes are 'online'. Should they be in 'offline' mode?
But I rescan the server and the repositories in Veeam, but I don't think Veeam sees them? I have set my proxies to use SAN only and they start using [san] it then go to [nbd] even though I have told it not to revert to network.
Hard Disk 1 [san] then
Hard Disk 1 [nbd]
When I add new repository, select the windows server and click populate I see C: and E: but not the VMFS volumes? MMC console sees the luns and I have put them in online mode, and that's it. So the Windows VM defo sees the luns.
They are iSCSI luns from an old IBM DS3300 SAN
Am I correct in that presenting the VMFS luns to the windows Veeam backup proxy is the way to go to use Direct SAN properly? I have been following the links below:

What am I missing? I have attached screenshots, any help helping me understand this would be greatly appreciated !

Running through the same scenario for our proof of concept for veeam. The volumes connected to the datastores should be offline and healthy. The volumes are presented to a windows server (scary as it may sound)

Hi Paul,
So basically the VMFS volumes that are presented to the Windows VM need to be in offline mode and not online like I have done?
Yes presenting them to Windows sounds like a nutty thing to do, but as long as they aren't mounted, you should be safe...or so I understand!
If I have set it up correctly why is it backing up using [nbd] network based? *EDIT* will it show network mode, because iscsi traffic runs across the network? If so I thought the basis for Direct SAN was that it offloads everything to the SAN, so there is no traffic?
As you can guess I am pretty muddled!
