i am really leaning towards a bug with ubuntu.
after changing the BIOS back to IDE mode and thus detecting the disks, i
booted up a livecd and proceeded to simply delete the partitions on the
disks with gparted. then, rebooted and changed the BIOS back to AHCI.
the disks are magically detected again.
so, i go and install ubuntu-server again on a third, identical server.
upon rebooting, the disks are no longer detected. the BIOS just gets
stuck at 'auto-detecting SATA PORT0'
i noticed something interesting in the installation, during the
partitioning. both disks initially showed up as 'free space' but, as
soon as i carved out the partitions like i did last time, they magically
showed up as raid/lvm paritions. so, something was still on the disks.
maybe i need to use dd to write zeroes to the entire surface of both disks?
