I've been experiencing this issue for a couple of months now where my ESX hosts lose connectivity with my iSCSI SAN vmfs volumes.

As a results the ESX hosts enter a nonresponsive mode the associated VMs disconnect and the only remedy is to reboot the host.

This issue happens randomly . I have escalated this issue with VMWare but I haven't had any solution to the issue yet.

I see no errors on my switches and there are no hardware issues as well. My SAN infrastucture is solid and there are 2 paths for every vmfs volume.

Did anybody else experienced a similar issue?

Hi! I have problem with using multiply iSCSI targets with single ESXi host (in my case they are two FreeNAS hosts, but I suspect that this problem will occur with any two iSCSI box of that same type/model).
