I guess I'll try hardware and scsi. Please excuse me if this is not appropriate. I was using dump to backup to a Exabyte 8700 (actually a 8505) 8mm tape drive hanging off a Adaptec 1510 when the system hung. I could not get any response from the console. I could ping the box but could not login from telnet. The command I used was: dump 0ubBf 128 14000000 /dev/nrst0 /mnt/u0 >>& log /mnt/u0 is a 1.5G partition. Running the same command earlier on smaller filesystems had no problem. info on tape host: Script started on Sat Dec 14 21:22:43 1996 dmes[501]ping@red:~> dmesg FreeBSD 2.2-960801-SNAP #0: Fri Oct 4 19:07:19 PDT 1996 ping@red.stepnet.com:/usr/src/sys/compile/RED Calibrating clock(s) relative to mc146818A clock... i8254 clock: 1193901 Hz CPU: i486 DX2 (486-class CPU) Origin = "GenuineIntel" Id = 0x435 Stepping=5 Features=0x3 real memory = 25165824 (24576K bytes) avail memory = 22560768 (22032K bytes) ahc0: at 0x1c00-0x1cff irq 11 on isa ahc0: aic7770 >= Rev E, Single Channel, SCSI Id=7, 4 SCBs ahc0 waiting for scsi devices to settle (ahc0:0:0): "HP C3325A 5020" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 2069MB (4238836 512 byte sectors) (ahc0:6:0): "TOSHIBA CD-ROM XM-3601TA 0725" type 5 removable SCSI 2 cd0(ahc0:6:0): CD-ROM cd0(ahc0:6:0): NOT READY asc:3a,0 Medium not present can't get the size Probing for devices on the ISA bus: sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA color <16 virtual consoles, flags=0x0> ed0 at 0x280-0x29f irq 9 on isa ed0: address 00:20:18:30:4d:08, type NE2000 (16 bit) ed1 at 0x300-0x31f irq 10 on isa ed1: address 00:00:e8:c2:a7:fd, type NE2000 (16 bit) sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16550A sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A lpt0 at 0x378-0x37f irq 7 on isa lpt0: Interrupt-driven port lp0: TCP/IP capable interface fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: NEC 72065B fd0: 1.44MB 3.5in fd1: 1.2MB 5.25in ft0: Archive tape wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): wd0: 329MB (675450 sectors), 790 cyls, 15 heads, 57 S/T, 512 B/S aic0 at 0x340-0x35f irq 12 on isa aic0 waiting for scsi devices to settle (aic0:2:0): "EXABYTE EXB-8505 0040" type 1 removable SCSI 2 st0(aic0:2:0): Sequential-Access density code 0x0, drive empty npx0 on motherboard npx0: INT 16 interface [502]ping@red:~> mt -t /dev/nrst0 status Present Mode: Density = 0x00 Blocksize variable ---------available modes--------- Mode 0: Density = 0x00 Blocksize variable Mode 1: Density = X3.136-1986 Blocksize = 512 bytes Mode 2: Density = X3.39-1986 Blocksize variable Mode 3: Density = X3.54-1986 Blocksize variable [503]ping@red:~> ls -l /dev/nrst0 crw-rw---- 2 root operator 14, 1 Dec 14 21:02 /dev/nrst0 [504]ping@red:~> exit exit Script done on Sat Dec 14 21:23:11 1996 Thanks in advance for anyone's help!
