That is probably the same card i'm using; it's actually a "Sun" card but as you say is OEM by LSI. > So, just to make sure we're talking about the same thing here - your > drives are SATA, yes > you're exporting each drive through the Western > Scientific raidbox as a seperate volume, yes > and zfs actually brings in a > hot spare when you pull a drive? yes OS is Sol10U4, system is an X4200, original hardware rev. > Over here, I've still not been able to accomplish that - even after > installing Nevada b76 on the machine, removing a disk will not cause a > hot-spare to become active, nor does resilvering start. Our Transtec > raidbox seems to be based on a chipset by Promise, by the way. I have heard some bad things about the Promise RAID boxes but I haven't had any direct experience. I do own one Promise box that accepts 4 PATA drives and exports them to a host as scsi disks. Shockingly, it uses a master/slave IDE configuration rather than 4 separate IDE controllers. It wasn't super expensive but it wasn't dirt cheap, either, and it seems it would have cost another $5 to manufacture the "right way." I've had fine luck with Promise $25 ATA PCI cards :) The infortrend units, on the other hand, I have had generally quite good luck with. When I worked at UUNet in the late '90s we had hundreds of their SCSI RAIDs deployed. I do have an Infortrend FC-attached raid with SATA disks, which basically works fine. It has an external JBOD also SATA disks connecting to the main raid with FC. Unfortunately, The RAID unit boots faster than the JBOD. So, if you turn them on at the same time, it thinks the JBOD is gone and doesn't notice it's there until you reboot the controller. That caused a little pucker for my colleagues when it happened while i was on vacation. The support guy at the reseller we were working with (NOT Western Scientific) told them the raid was hosed and they should rebuild from scratch, hope you had a backup. danno -- Dan Pritts, System Administrator Internet2 office: +1-734-352-4953 | mobile: +1-734-834-7224 _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
