Hi there.

I am Swedish so english is not my native language but I'll do my best =).

I have a Windows10 Vm and it's been running flawlessly for 1y+.
I upgraded my VM storage pool so yesterday I moved all my VMs the this new ZFS pool.
Everything went well but not for this W10 VM!
Out of 30+ containers and VMs this one has problems.
It can be started but it's IP does not show up. I have QMagent installed and it shows nothing. I use this VM to run Asheron's call, a vintage online game and I use Moonlight to connect to it. After migration to the new pool it cannot be reached from any PC on the LAN, nor pinged or trying to get IP from proxmox CLI (tested various methods).
I have a similiar VM that I host for a friend and it's working after migration.
Config file looks fine, VM console does not work (black screen) but it was like that before too.
I have moved both TPM7EFI disks as well on the nonfunctional VM just like the one working.

I have tried to search all kinds of solutions to this problem and after 2y of Proxmox tinkering I cannot find the cause or solution to this.
VM config is the same after migration (I tried and restore a backup of the VM but still not working...)
One thing is strange though. If I start the VM, it is runnign but do not appear to get a valid IP config.
Stranger yet is that my chars in the online game seems to be online but I cannot get the VMs IP from interface or CLI.

Running pve-manager/8.4.11/14a32011146091ed (running kernel: 6.5.13-5-pve)

Nooooo idea but 12h later everything works in that VM. No Idea what caused it. I have done nothing to parameters etc. Just works.
 
Need clarity on below points
1. Initiator number (IQN-123456789) --> mapped with Netapp storage 20 TB
2. same above initator number trying to map with new dell storage 25 TB, but we have create volume on dell storage 25 TB but its not discovering on promox, we already restarted iscsci and multipath-tools.service but still that 25 TB LUN not showing, clarity needed --> same IQN number can be used to two different storage?
