Had our ESXi host experience an "ungraceful" shutdown (power fail). Upon rebooting our Server 2019 VM boots to the blue "repair" screen and cannot be repaired - only option is to restore or reinstall.
Logs just show that an "error has occurred and cannot boot" message. Two other VMs (Linux variant) boot fine after power restore.
Hardware is an HP DL380 G9. It shows an "unknown status" on the PERC controller battery.
Would this PERC controller battery be causing an issue?
YES - plan is to replace it immediately - was just trying to get some insight into what may be the issue.
The Battery is meant to backup the write cache, if you had active I/O on that system and the writes were not committed and lost, then I would expect data corruption.

PERC on HP ??
If the VM can be seen at all, likely is not the RAID controller as any issues would mean that either the data store appears or does not appear in vCenter. One easy way is to storage vMotion the VM off the storage with RAID adapter issue.
Then server 2019 boot failure can be due to many reasons but Windows repair does not work 95% of the time. Best if can vMotion the VM to another storage/host then show the boot failure message.
Simply having a PERC on an HP unit could explain the error with the battery, the problem with the VM itself, that's another story, how does the VM attach to its storage?
Actually just spotted the date on this, I presume by now you have restored the VM from a backup and all is well again? ;)
Sorry all got my servers mixed up (I have some Dells as well).. This is a P440ar RAID controller on this HP.
Storage is configured as serial attached SCSI in VM ware.
And YES restored from backup so all is well, however on the same hardware. Unfortunately we're a small shop and I'm still waiting on authorization to purchase a new host server.
In the meantime the backups are running (both on-site and cloud) for all the critical data - everything else can be re-built in a couple of hours if needed (we have redundant DCs and DHCP servers - this one fail only affects the file shares that everyone uses... :) ).
