Hi,

as your iscsiadm show, your network is reset from the server-side.
Network problems maybe.

Thank you. I am able to ping out and ping in to my Proxmox host machine. I am also able to ping the SAN server IP as well as the both controllers in SAN. I doubt this is network issue. Strangely i am able to start VM placed in Controller A, but not in Controller B.

Ok then the client has zombies.
Try to reboot the node.

I rebooted both Proxmox & SAN Server, nothing has changed.

Perhaps it would be very helpful if you could point me to links/notes that will guide me in starting fresh setup, The existing configuration was done by a former colleague, he has left the organisation with no notes/documentation left behind.

Current setup;
1. Proxmox running on Dell PowerEdge R710
2. HP MSA SAN 2040 with 2 Controllers (A,B)

The problem with iSCSI is there is not one setting.
But if it works on Node B you can compare this setup.
Here is the generall Doku about this topic.
