3.2.2 MU3 an Veeam Storage Integration

[cali]

Hi,
have an issue, that after Update to 3.2.2 MU3 the Veeam Backup Storage Integration does no longer work.
HPE say this is a known issue and have to be fixed by Veeam, but Veeam does not have a fix and say before MU3 it works fine.

Anybody else have this?

I haven't seen this issue, but a few weeks ago, in my weekly VEEAM update email from Gostev, he mentioned it:

HPE 3PAR users - please be aware that upgrading to 3.2.2 MU3 breaks storage integration functionality in Veeam Backup & Replication due to this update breaking SSH connection to the storage. We have the hot fix already available for 9.0 U2, please refer your support engineer to Issue ID 84029.

Hope this helps.

Yes, thanks

thx storageguy138
Now get the Fix from Veeam in 5 Minutes.

@bajorgensen
MU3 = MU2 + all Fixes + additional Fixes
New Features are only:
- Improves Deduplication Store (DDS) defragmentation speed
- Various open source packages, such as libc, have been updated to address security vulnerabilities.
- Direct attach copper (DAC) cable support is expanded for HPE 3PAR StoreServ systems.

... after upgrading the inform os to 3.2.2 MU3 P41, we implemented although the patch in veeam! Thanks for the post here!

But now, we got a lot of events in 3par system:

Time : 2016-10-07 01:28:27 CEST
Severity : Major
Type : Rejecting SSH Connection
Message : SSH connection from www.xxx.yyy.zzz was rejected because SSH connections have been exhausted for this IP address.

where www.xxx.yyy.zzz is our veeam backup server!

As I know there is a maximum of 96 SSH-sessions possible on 3par ...

In Veeam-logs we can see a lot of errors, when Veeam-server tries to connect the 3par:

"Failed to connect to host 3par-storage: destination host is unreachable"
"Unable to establish connection to host 3parstorage on any IP address."
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"

Most backups finished - after 3 retries the Veeam-server was able to connect the 3par, but some did not - backups failed!

...?
... reduce sessiontimeout from default 1h on 3par?
... an option to increase the SSH-session max in 3par?
... available fix for veeam?

We got the Same errors after aplying the Patch.
Reopen a case at Veeam.
Veeam is analysing the Debug log and at the Moment they Tell us it is a Network Problem.
But we dont think because it Happens Right after aplying the Patch.

Just received a new Fix for the SSH Problem.
It includes now "Veeam.Backup.SSH.dll" and "Veeam.Backup.SanPlugin.Hp3PARLib.dll".

We have just upgraded to 3.2.2 MU3.

Now Veeam is unable to query the 3PAR properly.
Rescan storage provides a user authentication failed - I've logged a call to Veeam so will the hotfix fix this?
