we did VM migration (host&datastore) on our prod environment and suddenly the migration failed due to unreachable storage, and now that VM is inaccessible,
can someone help me with this problem please.
If the storage is inaccible then you can not access the VM. Make sure your storage is accessible then you will be able acces your VM as well.
yes you are right, but the storage is accessible and the vm is not, and that's the problem.
What is the current stage of the VM? can you re-register vm and try to power on?
