Try (from this): echo "- - -" > /sys/class/scsi_host/host?/scan
(partprobe also come to mind, but I don't think it's the answer, just a web-search word to try; if not the above echo, some obscure fight with udev maybe, assuming the driver is present, and not disabled by bios!)

The issue was the server was setup with virtual disk RAID configuration. Deleted RAID and recreated with the new disk all working now
