These are obviously Sun rejects. In the past they were connected with an Adaptec 2944UW controller, no problems. On a second system I have ST423452W and ST446452W (apparently EMC RAID rejects) on a Supermicro P6DGH with onboard Adaptec 7896/97 U2 controller. I did do a low level format of all the drives, using SCSITOOL to format all 9 at once on the newer box. For the ST410800WD: # camcontrol tags da0 -v (pass0:ahc0:0:3:0): dev_openings 64 (pass0:ahc0:0:3:0): dev_active 0 (pass0:ahc0:0:3:0): devq_openings 64 (pass0:ahc0:0:3:0): devq_queued 0 (pass0:ahc0:0:3:0): held 0 (pass0:ahc0:0:3:0): mintags 2 (pass0:ahc0:0:3:0): maxtags 255 The output for the other two drives shows 253 dev_openings and devq_openings, otherwise the same. Other than being about 50% dead out of the box the drives work fine. The 5 23GB drives are 1 vinum RAID5 array, the 4 46GB another RAID5 array. Performance is pretty snappy for old drives, and the fault tolerance works well (I've already tried removing, reformatting, and reinstalling a drive).
