Hi Stefan, I have a couple of DEC RZ26L drives on an SC200 controller (data only, not the boot device nor swap.) Presently I think they are jumpered to wait for a start unit command before they spin up (I'll fix that the next time I get into the box.) With -current of July 22, 1997, the boot probe works fine, and when fsck touches them I get a couple of complaints but thereafter everything is ok: ncr1: <ncr 53c810a scsi> rev 0x11 int a irq 11 on pci0.12.0 ncr1: waiting for scsi devices to settle scbus1 at ncr1 bus 0 sd1 at scbus1 target 1 lun 0 sd1: <DEC RZ26L (C) DEC 440C> type 0 fixed SCSI 2 sd1: Direct-Access sd1: 10.0 MB/s (100 ns, offset 8) 1001MB (2050860 512 byte sectors) sd2 at scbus1 target 2 lun 0 sd2: <DEC RZ26L (C) DEC 440C> type 0 fixed SCSI 2 sd2: Direct-Access sd2: 10.0 MB/s (100 ns, offset 8) 1001MB (2050860 512 byte sectors) (complaints until the drives come up... work fine thereafter) sd1: error code 1, retries:2 sd1: error code 1, retries:1 sd1: error code 1, FAILURE sd2: error code 1, retries:2 sd2: error code 1, retries:1 sd2: error code 1, FAILURE With -current from today, things don't go as well. I don't have the machine on a serial console, so I will paraphrase what happens. The boot probe does not succede and the system hangs. As in the log from above, we get to: scbus1 at ncr1 bus 0 but then before we see sd1 (partially incomplete hand transcribed): scbus target 1 lun 0: command failed (9ff) @ fa043600 ncr1 Aborting Job... ncr1:1: Error (10:0:) (8-0-0) (0/3) @ script 424 and the reset switch is my only friend :( I think it is an acceptable solution for me to jumper the drives so that they spin up on power, but I thought that this change in behavior was noteworthy enough to call to your attention. Regards, -Chris
