DC VM on Hyper V Failed to Boot

[JATSO]

Hi All,

 

Last night I rebooted the Domain Controller and Sims Server VM's.

 

A couple of issues if anyone could help as I am not that experienced using Hyper V and Veeam.

 

Issue 1

 

Domain Controller VM failed to boot up after updates were installed, when I checked the error it highlighted that a USB Hard Drive was not connected see image attached and and when i turned on the the hard drive it booted.

The USB is used for taking an adhoc backup for keeping in the safe in another part of the school.

The disk is marked as offline anyway if connected until a backup is taken when I bring it online.

Anyone know how I can get it to boot without having the USB drive attached and turned on.

 

Issue 2

 

Checkpoints in Hyper V console.

Veeam has created these checkpoints are they needed as they are dated last September.

To be honest I thought that Veeam was recreating them every time it ran a backup and I should just leave alone but thought i had better ask the question as I have read that they shouldn't be there.

This VM Server booted fine even though the DC didn't.

See image attached:

 

Any ideas? Thanks

Checkpoints on a DC were always a bit of a no-no - if you try to use them, and if you have other DCs, it all goes a bit mad. If you have Exchange, and possibly with AADC, it goes madder.

 

You should be able to merge that checkpoint in.

 

I'm not sure with the USB drive - I do similar but with iSCSI and the VM will boot.

RE: your USB drive, I'd have thought that if you just removed the hard drive item that you've circled in red on your screenshot, the VM will be able to boot okay. IIRC you'll be able to add it back later easily enough, without having to restart the guest OS.

 

RE: checkpoints, the naming of them suggests that those were created when restoring the VM from a Veeam backup. More generally, removing a checkpoint that parents the 'Now' item will involve Hyper-V merging VM files back together. It'll display its progress when doing that. If Veeam has been taking good backups in the time since those checkpoints were created, you should be okay to remove the checkpoints. It shouldn't upset the next Veeam backup, but if it does, you might just need to run a full backup rather than an incremental.

Yes I saw that about checkpoints I will try and remove them as suggested. Thanks

 

Yes the USB one is the main issue I shall try again later while I am on site.
