Hi, I'm trying to install a SCSI fuji 2266SH (1.2Gb) on a DECstation-3100. The drive has 512byte sectors. The drive is recognized by ``test -c'' in the prom and by the 'scsi' prom commands. I can probe it, and can run read/write tests on it with no problem. However, when attempting to boot, the drive isn't recognized. It doesn't even come up with device name 'unknown' -- it just probes the drive (light goes on) and then skips over the RZ entry. I tried booting with the Ultrix 4.1 tapes, and it gave me some message about (1) SCSI communiction XXXXXX ID = 1, SOMETHING = 0x12 (2) SCSI bus reset (3) message (1) repeated message (1) is garbled here because the display clears immediately, and then you need to reboot from TK50, a pain unto itself. A ``press return to reboot'' message would be nice here, DECdudes. So, has anyone seen such a problem before? Any possible fixes? I'll list the disk configuration below -- it's derived from descriptions in the manual. Cable lengths seem reasonable, but I'll double check that if nothing else. SCSI ID = 1 SCSI Time monitoring = enabled (def) Read ahead (256K) = enabled SCSI level = tried both 2 and 1/ccs Message mode = SAVE DATA POINTER issued for disconnection after xfr MODE Select = check condition status not reported PER default value = 0 Motor start mode = start on powerup SCSI bus parity = enabled synch mode xfr rate = 0.96 to 4.8Mb/s sync mode data transfer request = enabled SCSI time monitor mode = ACK signal wait is unlimited time Selection monitoring time is 250ms, 128 retries (def) UNIT Attention condition = SCSI standard (for command other than INQ, REQ SENSE or PRIO RESERVE, respond with 'CHECK CONDITION')
