Sorry about my previous message, and for starting a new thread (I''m a fast deleter). S10U2 supports SATA hot plug but just for a few SATA controllers (notably, not the one in the x2100, which is why I thought support was absent altogether). Judging from the log messages that were posted, you do not have one of those controllers. (i saw the text "gen-ata") <http://docs.sun.com/app/docs/doc/817-0547/6mgbdbsmb?a=view> See the section about SATA support. -frank

So another approach I could take is to buy one of the supported controllers, if they''re available on a card I could plug in. I can also make do without hot-swap, or possibly with needing to type some commands before physically removing the drive; that''s not too bad). And, the future being uncertain, support for what I''ve got may eventually appear, though nobody has said they know it''s being worked on. The porting of ZFS to Linux may also eventually solve my problem. I''m going to try installing the nv44 I''ve got, just in case that might have advanced the driver state of the art. -- David Dyer-Bennet, <mailto:dd-b at dd-b.net>, <http://www.dd-b.net/dd-b/> RKBA: <http://www.dd-b.net/carry/> Pics: <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>

So as of today, you''re still limited to using SATA controllers based on those two chipsets (at least they''re popular chipsets for SATA add- on cards). As Frank mentioned, the nVidia CK8-04 chipset which is present in the X2100 and (I think) the Ultra 20 is conspicuously absent, as are SATA framework drivers for the nVidia MCP55 chipset which is used in the new Sun AM2-based systems. I scour the weekly putback logs for any SATA-related changes and things seem kind of quiet on that front, and naturally the bugs logged for adding these features never reflect any updates. grumble groan. I really do wish Sun was more vocal regarding their progress in this important area. /dale

Also it''s one internal plus one external port; my motherboard currently has 7 internal plus 1 external port, I don''t have enough slots to replace the internal ports with this card. However, there''s a Supermicro card based on the Marvell that gives 8 ports in one slot, so I have options this direction.> > The porting of ZFS to Linux may also eventually solve my problem. > > > > I''m going to try installing the nv44 I''ve got, just in case that might > > have advanced the driver state of the art. > > Even in nv44, the SATA framework still contains only two drivers, one > for the Silicon Image sil3124 and the other for the Marvell 88SX6xxx. > So as of today, you''re still limited to using SATA controllers based > on those two chipsets (at least they''re popular chipsets for SATA add- > on cards).Yep, that''s the outcome all right. -- David Dyer-Bennet, <mailto:dd-b at dd-b.net>, <http://www.dd-b.net/dd-b/> RKBA: <http://www.dd-b.net/carry/> Pics: <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>
