Backup Exec 2010 R2 cannot use SAN Transport Mode to backup vCenter

IBM x3250M3 plugged a QLogic Dual-Port HBA Adapter
 - Backup Exec 2010 R2 , vCenter Server , NO VCB Installed as BE2010R2 claimed they don't need that anymore.

IBM x3650M3 plugged 2 x QLogic FC Adapter
 - VMware ESXi 4.1 ( Licensed vMotion , vStorage... etc )

IBM SAN Switch with 8 Port Enabled x 2
IBM DS3512 with dual controller ( currently I connect 2 pair from each controller to the SAN Switch A and B )

I assumed the FC connection is fine as usually I connect Port A to SAN Switch A and Port B to SAN switch B,
I can see the VMFS created from ESXi and successfully install guest OS without issue.

From the x3250M3 ( vCenter ) shows the LUN 29 ( same as it shows under ESXi ), the status is online and
heathly so I guess it fine too. However, I seems cannot backup anything by using SAN Transport Mode,
Backup Exec shows all vCenter and guest OS, I can tick them and everything sounds OK until I start the
backup job.

After the pre-processing of Backup Exec Job load, it returned Final error: 0xe0009585 - Unable to open a disk of the virtual machine.

I didn't set any special thing on the DS3512 and in fact I created a NTFS partition and I can have read / write access to it.

Can someone please give me a starting point where I can investigate it from ?

Thanks
William

I would double-check the authentication configuration that BE uses to connect to the virtualcenter server and also verify that the server can actively connect to the LUN's using the vcbsandbg.exe that comes with the VCB framework.  http://www.veeam.com/forums/viewtopic.php?f=2&t=2259&p=12224&hilit=vcbsandbg#p12224 shows some sample output and what you should see.

Even though you don't need the framework for BE, it might be a good test to verify that the LUN is completely accessible to any software.  If you've already installed the framework on another server, you might be able to just copy over the executable and run it???

Other than that, I would recommend looking at the logs for BE to see if it gives any more information as to why it's failing.

Thanks for your reply, I ran vcbsandbg.exe and it seems OK to see the VMFS partition with correct LUN ( no. 29 ).

In regard the authentication under BE, I can basically view all VM host and guest OS from the backup selection list so I assumed BE sees the vCenter and able to login ? Please see the screen capture with the resource credentials check in BE and shows OK too ( however it took about a minute just for 2 check, is it normal ? )

 BackupExec - Resource Credentials shows "OK"
I will try to come up with the log from BE shortly, is everything look normal up to this point ?

Thanks Jakirkhan

Any other more direct answer or trick comment please ? I read those weeks ago and not helping or probably i missed some point, but the reason i ask here is to get a more direct answer rather than reading all the guides. :)

http://www.petenetlive.com/KB/Article/0000349.htm shows that similar errors can be a result of problems with the VSS software which has me wondering...

-is this a domain controller you are having the problem with?
-do other vm's backup without error?

If the answer is 'Yes' to both of the above then the issue may not be with BE or VMware, but is related to the fact that when ESX tries to take a quiesced snapshot, it fails because AD won't be quiet long enough to allow the snapshot to complete.  

Either way, try taking a manual snapshot of the VM and check the option to quiesce.  Delete the snapshot when/if it completes and let us know the results.

Tried that but same result. The target is just a BES Express with 15 users.

Any more tips please ?

No it is just a member server with almost no traffic on it.

I tried to use VCB 1.5 and it detects the LUN and allow to start a full backup of VM however the speed is very slow ( about 1GB/30mins ). I cancelled it finally.

By disabling the Win MPIO feature in 2008, I success created a Full VM backup ( 7.66GB in about 5mins ). I then go back to BE and perform the same backup by using NBD / SAN mode however none of them create the backup and return the same error - unable to open disk.

I am considering should I perform a clean installation of BE or anything else that I can do with that ?

So far...

1. I installed only the Backup Exec Agent on the VM, is it good enough ?
2. VM VSS is removed to make sure no conflict to VM VSS.
3. MPIO is running however I disabled the multipath and left only 1link active. ( this improve the speed of VCB right away ).
4. In a way, it proves the connection between VCB <> Win2k8 <> IBM DS3512 all OK ?
5. Permission shouldn't be a problem as I am using the same username and password all the time.

So not the question is, what is happening with BE 2010 R2 ? None of NBD / SAN is working so far.

Please HELP !!!

Have you opened a case with Backup Exec, if you escalate it you may get someone that can help.  The new R3 build also integrates with vCenter, may be worth a try.
