I'm installing on a remote server via KVM Console, and I do not have physical access to the server. The server has twelve disk and one sata-dom for OMV. I can't disable the scsi controller i BIOS as the sata-dom is residing on it.
The disk contains important data, and currently there is no backups available.
Does the installer really delete all the disks or is it just a precaution? Are there any other mitigations i could use?
