Replaced my RAID card in my Dell R710, and imported the foreign configuration from the last RAID card, ESXi started normally but the VMs are invalid and the datastore is gone. I'm going to guess that this is because of the new RAID card. But how do i retrieve the datastore that I had my VMs on?


From vSphere you can choose to add a data store, you should be able to select Disk/LUN then select the LUN that has the datastore name listed in the "VMFS Label" column. That should tell you this was previously a Datastore. Once you hit next it should give you the option to keep the existing signature and add it back as a datastore. Here is an article I found on the topic as well for more supporting information:

  • Glad to help! Were you able to see the Datastore from there? – Chris Alderson Jun 1 '17 at 20:58
  • Yup. I'm using ESXi 6.5, and I tried to do that with the Web interface (before posting here) but it just wanted to format it. I forgot all about the vSphere client. Once I used the vSphere client to create a datastore it recognized the Datastores as you said. Thanks a ton! :) – Kaiden Rogers Jun 1 '17 at 21:01
  • No problem at all glad to hear it! Losing something like your Datastore is always a scary prospect! – Chris Alderson Jun 1 '17 at 21:06
