Hello, we lost power to our esx + san environment, and my backups have been failing on VEEAM. I went into vmware, and saw this message, however the disk is attached in the VM. How do i fix this?

Hello,

Valid if the datastore where the VM is hosted are all vmdk that belong to that server.

Validate that the datastore is connected to all ESXi hosts.

Additional in the VM of Veeam Backup, go to the configurations of the VM and verify that it has not attacked any disk of another server. If you have another disk connected from another vm, disconnect it.

Is the SAN even presenting the LUN? You have to look at the SAN management console to see that.

you are going to remove the disk from the vm, if the vm of the veeam backu has a disk of a different vm connected.

this happens when the veeam backup initiates the backup process on the servers that you configured for the backup tasks.

and when it finishes the backup process it does not release the disk of the vm that it is backing up, if you want to share images to see it better.

Please do not remove any disks at this time!

You state the disk is there?

Did you check it’s on the datastore using ESXi shell?

If you do not have another disk connected from another vm, then it is not necessary to remove the disk.
