Datastore missing after reboot

[dherremans]

After a reboot, 1 of my 3 datastores is missing. VmStoreTom2

All disk are good. (see disk list.)

When I list the volumes:

I see that the link of VmStoreTom2 is in red.

Disk list:

I have 2 critical machine on that datastore and need to recuperate them.

Thanx for the help

What's the status of this disk array in your server's array configuration/management tools environment?!

 Can you check them once again?

However, please give more information about your server's vendor ...

Its possible that UUID change can do this . 
Try rescanning storage and adapters
