scsi disconnect on one ESXi 5x host but not second

[bittrekker]

Searching through the forums, it appears that the issue that I'm having has been experienced by others after they upgraded to esxi5, addded a software iscsi, or restarted management agents; however, the esxi server hasn't been touched by anyone in ages, so I'm posting a new thread. Most of all, I want to make sure that I don't lose everything on all of these Windows servers.

Two separate ESXi 5 hosts connected to a SAN. On one of them, I can connect using vSphere and all of the guests are up. The problem host, however, I can only connect using SSH (and of course I can ping the host). vsphere on that host returns error An unknown  connection  error occurred. The request failed because of a connection  failure.  (Unable to connect to the remote server). And as mentioned, the guests aren't showing up on the network.

One more note, I'm trying to do this remotely since the office building is locked up. I can't reboot the server, even with reboot -f. I assume this is because esxi still wants to control the shutdown processes with the images that it cannot connect to?

Here's all the info that I've been able to get:

/sbin/services.sh restart returned:

Had to hardboot and it reconnected. Couldn't run command reboot -f to restart. Of course, there were typical issues with some of the servers appearing not to come up right away because some were in recovery mode; restart services, etc. Not a lot of fun, but I'm glad it was an easy "repair" with no damage.
