DSS - iSCSI connection lost

[ottl05]

Hello,

we´ve got two DSS, and I´m using iSCSI-Volumes. (because with NAS and DFS, I can´t use the windows filepermissions)

The targets are mounted to our windows servers. I created snapshots for one Volume from 07.00h to 20.00h, for every weekday one snapshot.
Now I need to test the snapshot-feature fpr restoring data, but this is another matter.

So far so good.

Now I noticed, that at 20.00h every evening our servers are loosing the iSCSI-connection to their targets!
Why? Whats the Problem?

I heard that the latest version of DSS will fix your problem.
You may need to reconnect to targets after upgrade.
Were there any event errors on the MS server

let us know how it works out
