Thank you for that really fast reply.
Ok, I found the previous configured in the Static discovery tab, thank you for that hint.
But now, even after I did restore the addresses manually, the iSCSI volume does not get connected in ESXi.
After testing a little, the volumes now disappeared in ESXi, but the iSCSI device is still there.
When trying to "add new storage" I see the device, but when trying to find the partition table,
ESXi says "Loading..." and does not find anything for a long time... ???
On the DSS V6 side, be sure the LUNs are activated, even toggle them off/on.
Reboot the ESXi box.
If you are using the latest build of DSS V6(6335), check the SCST compatibility settings from the console. This is mentioned in the release notes.
Thanks again for help.
I hava a failover config with two paths and I put in the IP addresses in the wrong order. After switching these two the correct order, it's now back to work.
