Storage missing on Esxi host
Hi Experts,
This morning we conducted a high availability test on our virtual infrastructure. We have 2 esxi 6.0 hosts connected to a dell md3400 direct attached storage. When our esxi host was shutdown the HA worked fine, but the LUN from the storage was gone.
All looks well on the Storage Array itself, the host is in the group and LUN and port identifiers for the host appear to be fine on the MD3400. On the host the PCI storage adapter is there, but no storage.
I did a re-scan on the host and rebooted the host again and still no storage.
Thank you

That may not be quite right, disconnecting a cable makes it fail back to the other path so there may still be a fault, one path may still not be working properly, The recovery guru should complain if one path is down.
I can look through the majoreventlog.txt from the SAN tomorrow to see what's what although whether you can upload the whole support bundle to EE I'm not sure.

Thanks Andyalder,
I do see what you mean. One of the channels is down, but the cabling looks right.
I did not see any errors or any path down alerts from the recovery guru unless i am not looking in the right place.

Early in the day i checked to make sure the cables were still locked/attached in and they were fine. This afternoon after posting the question i went down and removed them from the host and plugged/clipped them back in and the array was back. Not sure why a physical reattach of the cables from the host would need to happen, but it worked.
Thanks for the replies.
