In my opinion you are best off using glabel(8) to give names to the
disks. This way you can name them in a way that makes sense to you.
Additionally, when you create the ZFS pool you will use the glabel'd
names. This means that the pool will still come up properly if
something causes your devices to be numbered differently (i.e. a drive
dies and you happen to reboot the system).
1) In the event of a disk failure, how do I trace back the name such
as adX to a physical drive in the enclosure? Is there a way to take
the drive offline then use atacontrol to spin it down or something so
it is easy to identify?
Depending on your controller it is also probably worth it to use one of
the SATA-specific drivers in FreeBSD 8 - these are ones like ahci(4) and
siis(4). While the generic ata(4) driver will work for pretty much
everything, the updated AHCI drivers can take advantage of some more
features. Enable the modules at boot to use them.
Any tips would be greatly appreciated.
