Notes:
The "Disk Group" is the group in the PERC bios associated with a RAID0 per physical disk. They appear to translate to the mfid? number used in FreeBSD. For example, Disk Group 0 maps to mfid0 (physical disk E1:S0). Disk Group 9 appears to map to mfid9 (physical disk E1:S11) Unfortunately, these group IDs seem to change when physical disks are added/removed, so when "mfid5" failed, the disk name changed on reboot and mfid5 no longer referred to the failed E1:S5 but now instead refers to E1:S8. The only way to obtain this mapping is by viewing the PERC BIOS. Fortunately, ZFS seems to be able to detect this and is able to reconstitute the zpools, but it makes it very difficult to figure out what physical drive maps to which mfid? device, and replacing drives requires rebooting the machine and verifying the changed device mappings. Some of this can be identified with mfiutil, but the canonical disk group to physical disk mapping is only available via the PERC BIOS.
