OpenIndianaでSATA port multiplier+ZFSがしたかった

勢い余って，eSATA 2 portのPCI Express x1カードを購入． まだまだ右も左も分からんのでメモ．

prtconf(1)やscanpci(1)を使ってデバイスを探す．

$ pfexec scanpci
(snip)
pci bus 0x0020 cardnum 0x00 function 0x00: vendor 0x1095 device 0x3132
 Silicon Image, Inc. SiI 3132 Serial ATA Raid II Controller
(snip)

$ /usr/sbin/prtconf -vD
(snip)
pci1095,3132, instance #0 (driver name: si3124)
(snip)

(driver name: si3124)と出ているのでsi3124ドライバがアタッチされている．

んで，manを見てみると…

# man si3124
DESCRIPTION
     The si3124 driver is a SATA framework-compliant  HBA  driver
     that  supports Silicon Image 3124 and 3132 SATA controllers.
     Note that while the Silicon Image controllers supports stan-
     dard  SATA  features  including SATA-II disks, NCQ, hotplug,
     port multiplier and ATAPI disks, the si3124 driver currently
     does not support NCQ, port multiplier or ATAPI features.

port multiplierは未対応だそうで…ショック．
