i have two hosts runnig esxi 5.5 .
there are 2 data store on each host one is on the local drive and the other is from SAN storage and all of the vms are running on a datastore created on SAN storage.
yesterday there was an improper shutdown of hosts because of some power issue in datacenter and i find that most of the vms go back to some previous configuration as i created lot of reports on CA server and now i did not find these reports.some vms were configured for sso and now they have lost all of the configurations.it happend 2 times during the last two months
i try to find the logs but i did not get any clue except improper shutdown of hosts. if u have any workaround for this prob let me know as i checked almost every thing in vcenter and on esxi hosts and i last time i deleted all the snapshots on all the vms.
if all the vms are running from the datastore created on san storage then improper shut down should only effect the HBA's but vms going to some previous state as there is no snapshot is out of my mind.please help what should i do
