Veeam not Using defined Server ISCSI targets. MPIO

Post by haris2887 »

Hello.
i have a problem with veeam that no-one seems to be able to solve, Including Veeam Support. case 00640986

I have setup ISCSI targets in my windows server 2012R2 machine and i can connect to the SAN ( offline disk shows in disk manager). I have also setup server 2012R2 MPIO.
Image

When i run a backup JOB .
Veeam automatically makes another Iscsi session and does not use my existing session. Because of this behavious the backup fails because the SAN in our enviroment needs CHAP authentication , when veeams Makes the new iscsi session it does not use CHAP hence it can access the SAN.

There is the session created by Veeam to access the SAN.
I then i went ahead and disabled CHap auth on the SAN. and Bang! everything works, Screen shot below shows the Iscsi sucessfully connected to SAN.
Image

Here is my MPIO configuration SHOWING 2 Paths

Code: Select all

Re: Veeam not Using defined Server ISCSI targets. MPIO

Post by Vitaliy S. »

Hi Haris,

Veeam should not create any new iSCSI targets during Direct SAN mode, unless you're using integration with storage snapshots. I see that you're using HP LeftHand storage, so can you please clarify if you would like to use direct SAN mode or storage snapshot integration to backup your production VMs?

If it is the second, then CHAP authentication is not supported in integration with HP storage yet. You can either backup production VMs using direct SAN mode with CHAP authentication (Veeam will be using existing iSCSI targets) and disable storage snapshot integration checkbox in the backup console or use storage snapshots for backing up the VMs, but with no CHAP authentication.

Let me know if that helps!

Hi Thanks for your Reply.
Yes we are using storage snapshots with HP store virtual.

Thats a bummer that veeam does not support CHAP when using storage snapshots.
Is this a freture that will be introduced in V8.

As far as I know, this capability is not a part of v8 release, but it is tracked and has chances to be introduced in our next updates/releases.

hi

Did this ever got updated that chap authentication is allowed via storage snapshot integration?

How is the best way to configure this with netapp solidfire?
We are making a backup from the iscsi disk to local storage.

Regards.

Additionally:
We get the following error:
1/22/2019 10:06:18 PM Unmask of volume [24] to hostname [veeam_MicrosoftInitiator] and IQN [iqn.1991-05.com.microsoft:veeam] failed: xPermissionDenied

how do we configure the solidfire and iscsi to work with storage integration?
We tried with CHAP and without CHAP authentication. Both failed on the storage integration way.

What is the transport mode on the proxy for this? I used direct san without chap authentication and the iscsi mounted > works but isn't really fast.
In automatic mode and with storage integration enabled I get the above error. (no chap on the Solidfire ISCSI volume).

thx in advance.

Update with Case # 03379095
Anyone has experience with veeam and solidfire configuration? Also with the snapshot storage integration?
We found out the the snapshot volume that is created by veeam not have the correct access group and therefore no ISCSI access to backup from.
When during backup job added manually to the access group the backup is completed successfully.

How can this process be automated?

Thx in advance.

Post by Ryan S »

do you see any unallocated disk at windows disk management of all the assigned backup proxy?
if your configuration are correct you should see those disk appear as unallocated black bars, those disk only for view purpose we must not configure anything on it...
After that your Veeam shall be able to proceed direct SAN backup method

second thing is how about iSCSI as IP not IQN ?

Hi

Yes I can see the volume I want to back-up in diskmanagement. I only have set the disk online but nothing else.
I'm not using direct SAN but storage integrated snapshot.

I tried direct at one point but if I enable storage integrated snapshot the backup fails.
1/22/2019 10:06:18 PM :: Error: Unmask of volume [24] to hostname [veeam_MicrosoftInitiator] and IQN [iqn.1991-05.com.microsoft:veeam] failed: xPermissionDenied

What do you mean ISCSI as IP. It's the newly created snapshot by veeam that is not able to connect as it has no access group permission on the netapp.
The disk I want to backup is available, the snapshot isn't .

The problem is solved. The rights of the user connecting to veeam on the netapp must be leveled up to clusteradmin and volumes.
