ESXi 6.5 U3: Loss of my datastore

[tafkap]

Hi,

For a test i deactivated the passthrough on my PERC H730P controller (Dell PowerEdge R920 server), i restarted my server and i lost datastores, what is happening? Now i can't reactivate the passthrough on my PERC, i tried by editing the esx.conf file but i doesn't work.

Help!!! :smileycry:

Hi Prince fan

I dont think that the referenced post will help you.

There we had to deal with physical drive issues.

Editing the esx.conf is already the appropriate idea - unfortunately that is not as straight forward as you assume.

Please have a look here instead:

How to disable ESXi Passthrough my findings

If you think that this approach sounds like a nightmare I have to agree completely - but  please look into it anyway.

At the moment I am not aware of any more convenient workaround.

I solved my problem by reinstalling ESXi server, with option keep the VMs, i did this and my datastore reappeared, I then recreated the VMs from the files on the datastore, and now everything works perfectly

Good - so your original plan to edit esx.conf was spot on.

For an ESXi host with an easy, basic configuration the sledgehammer approach also can be done faster than the scalpel-and-pencil approach using a Linux LiveCD.
