I have 4 independent md arrays that are all in one large LVM virtual drive. Some drives have started to go bad. So as I replace them with new Seagate 120 gig PATA drives, I get errors in syslog similar to this: Jun 15 22:45:14 blimp kernel: 3w-xxxx: scsi1: Command failed: status = 0xc7, flags = 0x1b, unit #2. Jun 15 22:45:14 blimp kernel: 3w-xxxx: scsi1: AEN: WARNING: ATA port timeout: Port #2. Jun 15 22:45:14 blimp kernel: 3w-xxxx: scsi1: Reset succeeded. Jun 16 04:40:58 blimp kernel: 3w-xxxx: scsi1: Command failed: status = 0xc7, flags = 0x1b, unit #2. Jun 16 04:40:58 blimp kernel: 3w-xxxx: scsi1: AEN: WARNING: ATA port timeout: Port #2.

Usually it starts up fine, but when the array is idle and I attempt to access it, I see these entries.and a brief delay, then the array works fine for a while. I replaced it with a 200 gig older drive (yes, I know it is limited to 137 gig), and this problem shifted to unit #3 (same thing, it is also a recently replaced new seagate 120gig). I replace unit #3 with several different 200 gig drives (new hitachi, new seagate, old WD) and always now I get on startup: Jun 23 20:54:27 blimp kernel: 3w-xxxx: scsi1: Command failed: status = 0xc1, flags = 0x11, unit #3.

I'm not really sure what to do now. Regards, Michael Stumpf
