Case # 01976501

Guys, we updated our 3PAR to 3.2.2 andare having intermittent backup issues. We are getting the SSH timeout issue

We have applied the "3par hotfix" as advised by Veeam Support.. but still we are seeing backups fail.

Support tell us that they only way forward is to move to ver 9.5

Anyone else updated and applied the fix.. but still having issues ??

Hi

We use Veeam 9.5 Update 1 and updated last thursday from HPE 3PAR OS 3.2.1 MU1 (patch 4) to 3.2.2 MU3 (patch 52).

Since then we are using more than double the time for backups because - as HPE support says "It does seem that Veeam is unable to detect the snapshot that is created on the 3PAR." In fact the storage snapshots are taken but not exported for approx. 10h and then veeam seems to continue (like waiting for a timeout) and the backup runs fast as it used to be.

I am just wondering that I was in touch with Veeam Support (# 5317390161) for more than a week now and delivered all necessary details but until now they did not seem able to discover that. I just added the details to the support case and am looking forward to get the support hotfix and test - will keep you updated.

Could you please verify the Veeam support case ID, since the one provided doesn't look valid. Thanks.

Hi there

Well I will know soon if our backup runs fine with 3.2.2 MU3 and Veeam 9.5 Update 1 as I am going to run it tonight again. If it does not it is most proably due to erroneous WsAPI on HPE's side (check also https://h20565.www2.hpe.com/hpsc/doc/public/display?sp4ts.oid=5044394&docLocale=en_US&docId=emr_na-c05225720 and look for WSAPI and MU 3.2.2 MU4).

On the other hand - if you folk encounter a problem with the iSCSI connection discovery (will appear after updating HPE 3PAR) then please read that:
HPE implemented an iSCSI specifiation feature called STGT (Send-Target Group Tag) with 3.2.2 MU3 which basically adds a new tag for connection availabilities. After the update the STGT values are per default set to the TPGT values (e.g. 21, 22, 121, 122) but the kernel on the 3PAR cages are not made aware of that breaking all new iSCSI discoveries (and dynamic discoveries). So you will have to change the STGT values forth (and it is recommended to set it back to default again) in order to make iSCSI discovery work again. Be aware though if you have active Smart SAN target driven zones, to do a removehost first. If not done first, you will not be able to manage the zone on the switch associated with this port. But now, check the actual values of STGT and set them to (e.g. 1 and then back to 21) for port 0:2:1
Code: Select all
cli% showport -iscsi
cli% controliscsiport stgt 1  0:2:1
cli% controliscsiport stgt 21  0:2:1

You are done and iSCSI dynamic discovery will work again :D

I can confirm that the backup works fine and without initial delay after:
- having changed the STGT values on 3PAR forth and back to default
- rediscovered the iSCSI target on 3PAR from the source server
- rescanned the storage in Veeam's storage infrastructure
