In an attempt to recycle some old PATA disks, we bought some really cheap PATA/SATA adapters, some of which actually work to the point where it is possible to boot from a ZFS installation (e.g., c1t2d0s0). Not all PATA disks work, just Seagates, it would seem, but not Maxstors. I wonder why? probe-scsi-all sees Seagate but not Maxstor disks plugged into the same adapter.
Such disks have proven invaluable as a substitute for rescue CDs until such CDs become possible. The odd thing is that booting from another disk, ZFS can't see the adapted disk even though it is bootable. Could the reason be that there's no /dev/rdsk/c1t2d0, but there are c1t0d0, etc.? Format sees the disk but zpool import doesn't (this is on SPARC sun4u). This isn't at all important, just curious as to why this might be and why zpool import can't see it at all, but zpool create can. Gotta say how happy we are with the MPT driver and the LSI SAS controller - fast and reliable - petabytes of i/o and not a single zfs checksum error! This has little to do with ZFS, but should it be possible to see a PATA CD or DVD connected to an MPT (LSI) SAS controller via one of these adapters? Though I'd ask before forking out for a SATA DVD drive - just hate to put perfectly good drives out for recycling. Maybe someone can recommend a writable BlueRay SAS drive that is known to work with the MPT driver instead...
