I'm facing a peculiar issue with my Hyper-V cluster and I'm hoping someone can shed some light on it. Recently, during routine maintenance involving the live migration of VMs, one of my hosts lost all connections to the iSCSI storage and the cluster. This happened right after I removed a DVD drive from a running Gen 2 VM on a different host, as it wouldn't migrate from 2019 to 2022 with the drive attached. I thought removing the DVD drive wouldn't impact anything, especially since it was a different host, but the same connection loss occurred again later when I removed another DVD drive from yet another VM. From what I've read, it's not recommended to remove DVD drives while VMs are running, even for Gen 2. Has anyone else experienced this kind of disruption? How could one VM's DVD drive removal cause a whole host to lose connectivity, even momentarily? Would appreciate any insights!

I've encountered something somewhat like this with ESXi. When I tried to eject an ISO from a Linux VM, it would freeze until I confirmed a prompt. But a complete host-wide storage disconnect? That’s on another level. Gotta give Microsoft credit for that kind of weird behavior!
