Hi all,
I've been beating my head against a wall the last couple days trying to figure this out.
I just rebuilt my BE2010 server from Windows 2003 to 2008R2. In the process, I decided to consolidate my VMDK backups into BE, rather than using VMDR. The test job completed successfully using the NBD transport, and got about 1GB/min. Not bad, but I've read that the SAN transport is substantially faster, and has less overhead on the host servers. So I looked through the BE Administrator's Guide... and the Symantec forums... and the VMware forums... and every random blog I came across... and could not find any solid info on getting this configured.
Based on the bits and pieces I was able to gather, I used diskpart to disable automount (and to scrub the automount cache, just in case), attached my media server to my SAN via iSCSI, and confirmed that the VMFS LUNs showed up in Disk Management ("online", but no drive letter, and I didn't have to initialize them or anything). But every time I try to run a job with only the SAN transport selected, I get the following error within a few seconds.
Backup- VMVCB::\\VCENTER-01.domain.local\VCGuestVm\Datacenter01\vm\Infrastructure VMs\VM-W8-DC01 V-79-57344-38277 - Unable to open a disk of the virtual machine. VixDiskLib_Open() reported the error: You do not have access rights to this file
Similarly, this error brings up very little useful info anywhere. I tried selecting the VM directly through one of the ESX hosts (using the root account) rather than through vCenter, with the same result.

If you watch the byte count during the job, it should get to just over 20,100 bytes and report "snapshot processing" for a few minutes before failing. What seems to be happening is that Backup Exec can not mount the snapshot because it fails authentication or the media server (where Backup Exec is installed) can't access the ESX host in the way that the VSphere server has it labled.
1. Create a new user account and give it administrator rights in vCenter or the ESX host and attempt the backup again using the new user account. Ensure that the password does not include special characters such as & or @.
If this is changed and the same results are experienced
2. Determine exactly how VSphere is listing the ESX hosts in Host View. From the media server ping that exact name. If you can't reach it, create a host file on the media server with the IP Adress and the exact host name of each ESX host.

I've got an odd issue where all of my VMs except 1 back up using the SAN transport method. The other VM requires NDB in order to back up. I'm using 2010R2 and vSphere 4.1, hardware level 7 on an iSCSI SAN. The VM that only works with NDB has the same permissions and is generally configured the same as the other VMs as far as I can tell.
Any idea where to look if only 1 VM won't back up with SAN but 24 other ones will?

Jim,
Are all your Vm's located on one LUN/Volume or do you have multiple LUNs/Volumes??
What is the exact error message you receive ?
11-06-2010 03:08 PM
I have multiple LUNs/Datastores, but the VM in question is located on a VMFS volume that has other VMs that back up just fine using the SAN transport.
Error message when I enable only SAN transport and disable NDB:
V-79-57344-38283 - The selected transport mode is unsupported by the current setup.
VixDiskLib_Open(): Transport mode 'ndb' used for opening the disk.
The link points to a bunch of stuff about backing up templates, but this is not a template, nor has it ever been. The other error page it links to is an acknowledgement by Symantec that their program is broken, but they don't really have any plans to fix it unless you call Symantec Sales and tell them you're pissed off. :)

I'm experiencing the exact same issue. We have about 20 VM's and three of them fail with the error:
Backup- VMVCB::\\SAA-VC01\VCGuestVm\(DC)SAA Rotterdam(DC)\vm\SAA10
V-79-57344-38283 - The selected transport mode is unsupported by the current setup.
VixDiskLib_Open(): Transport mode 'nbd' used for opening the disk.
This ofcourse only occurs when I try to force the SAN transport option by disabling the other options.

Symantec are investigating some problems with this symptom, as such please confirm
1) What Languages your media servers are installed in
2) Whether your media server is also your vCenter Server
3) Whether your media server is a physical machine or a virtual machine
Thanks

Hello.
I have the exact same issue. We have 41 VM's and two of them fail with the error:
Backup- VMVCB::\\SAA-VC01\VCGuestVm\(DC)SAA Rotterdam(DC)\vm\SAA10
V-79-57344-38283 - The selected transport mode is unsupported by the current setup.
VixDiskLib_Open(): Transport mode 'nbd' used for opening the disk.
In the Backup Job I force the SAN transport option by disabling the other options.
Is there any solution?
The answers for Colins Questions:
1) Media Server Languages = German
2) No, Media Server and VMware vCenter are seperate Machines
3) Our Media Server is a physical Maschine.

It seems to be a known issue:
You can try to contact Symantec Support about the status of this issue.

Where this is a French customer, the problem appeas to be caused by the accented é character that is used to define LocalSystem (LocalSystemé) against the startup of the BE Remote service. It appears that the vStorage API tries to create a tempfolder during the backup based on this user and because it cannot handle the accent it get an access denied message against the folder creation/use and fails. We are currently investigating this in consultation with VMware.
At this current time we have not specifically identified another languuage that might have a problem with an accent in the LocalSystem account - however should you have this issue and be using a server that is not configured in English - please check the characters used to define "Local System" for that language and let us know if there are any accented or non-English characters present.
