These are SuperMicro GEM enclosures that are rated for U320 and they weren't cheap in my book but then that's a relative thing. SCSI is never inexpensive. Sometimes I spell it $C$I. I'm not familiar with SuperMicro GEM enclosures, perhaps someone who is could comment on the quality

I power cycled the server after my users went home, checked the cables, and after about a hour's worth of hair-pulling nvram/disk configuration mismatches I finally got the system back up with sd0 in degraded mode and the other two optimal. yay Brought the system up to the most

Fortunately, these are internal enclosures, and the only thing on each of those cables is the LSI card on one end and the Supermicro GEM enclosure on the other. Does it have an expander? If it does you need a 2 connector cable. Still, I'm not opposed to getting good cables and I can

I created it with bioctl, but my version is from a September 1 snapshot so it is before your fix. There is a good chance that the hotspare does not work prior to that fix. I'd say this explains what you see. The server ran flawlessly for 2 years now, and I'll bet it's been a year since

Hitachi's drive testing tool seems to be windows only, so are there any drive checking utilities that can check an individual drive when it's a part of a RAID1? Or is it safe to assume that if the drive fails in the RAID it is really dead. I'm trying to make sure I'm not seeing some
