Allo looks akoe wihin lizzard but drive was gone on hypervisor so we want to reconnect bet when doing we donot get a LUN. So we cannotr attach the drive

Post patching, the LUN disappeared from the system and disk is showing was showing unplugged. So we consulted citrix and they tired to forget the SR and when trying to recreate the SR, now, we cannot see the LUN.

Citrix is now not supporting this scenario.

Within lizard all looks oke but when we trying to attach this drive we are getting no LUN back

Which tool you are using the attach the disk, XenCenter?

Without log files it is difficult to understand how the problem was created and how it could be solved.

I observed in the result of Node2(Slave) iscsi-cfg status.
ISCSI Target service is in stopped state. The service should run as like Node1. Can you please check.

No, it should stay stopped! Please look at the sceenshot, you can read there "exepcted stopped".
Only the primary node should have the run status.
