Patrick,
I thought I moved / migrated this vm from the host to another host.
then I mounted a .iso and installed esxi5.1 on my host.
This was the last of 6 hosts,..
My other 5 hosts also cannot see data on the LUN, when I look in EVA it seems everything is ok.
When I add the disk again to my hosts blanc disk...
what can be the cause..of the lost vm and blanc lun
during install of 5.1 I choose for sd to install esxi on.
luns stayed connected as they where connected the whole migration of the other hosts, no problem.
