Have only ever done 3 or 4 successful backups, and the other 20 or so tests have failed. Using an Intel SR2 Motherboard (Dual P3/1ghz), with onboard Adaptec 7899 Controller. The Tape unit is on ID 1 Tar comes back with the error tar: can't write to /dev/sa0 : Input/output error And the dmesg log is larger, it says (sa0:ahc0:0:1:0): SCB 0x8 - timed out in Data-out phase, SEQADDR == 0x56 STACK == 0x67, 0x164, 0x0, 0x8e SXFRCTL0 == 0x80 ahc0: Dumping Card State at SEQADDR 0x56 SCSISEQ = 0x12, SBLKCTL = 0x6, SSTAT0 0x0 SCB count = 20 Kernel NEXTQSCB = 14 Card NEXTQSCB = 14 QINFIFO entries: Waiting Queue entries: Disconnected Queue entries: QOUTFIFO entries: Sequencer Free SCB List: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Pending list: 8 Kernel Free SCB list: 15 16 17 18 19 0 1 2 3 4 5 6 7 9 13 12 11 10 Untagged Q(1): 8 sg[0] - Addr 0x6f82000 : Length 4096 sg[1] - Addr 0xeba3000 : Length 4096 sg[2] - Addr 0x1cfc4000 : Length 2048 (sa0:ahc0:0:1:0): BDR message in message buffer (sa0:ahc0:0:1:0): SCB 0x8 - timed out in Data-out phase, SEQADDR == 0x90 STACK == 0x8e, 0x67, 0x164, 0x0 SXFRCTL0 == 0x80 ahc0: Dumping Card State at SEQADDR 0x90 SCSISEQ = 0x12, SBLKCTL = 0x6, SSTAT0 0x0 SCB count = 20 Kernel NEXTQSCB = 14 Card NEXTQSCB = 14 QINFIFO entries: Waiting Queue entries: Disconnected Queue entries: QOUTFIFO entries: Sequencer Free SCB List: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Pending list: 8 Kernel Free SCB list: 15 16 17 18 19 0 1 2 3 4 5 6 7 9 13 12 11 10 Untagged Q(1): 8 sg[0] - Addr 0x6f82000 : Length 4096 sg[1] - Addr 0xeba3000 : Length 4096 sg[2] - Addr 0x1cfc4000 : Length 2048 (sa0:ahc0:0:1:0): no longer in timeout, status = 34b ahc0: Issued Channel A Bus Reset. 1 SCBs aborted (sa0:ahc0:0:1:0): failed to write terminating filemark(s) (sa0:ahc0:0:1:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM command to clear this state. I have gone into the SCSI Bios and changed negotiaton from Ultra/160 right down to Ultra/40. I'm pretty stuck right now, and would appreciate any suggestions. Thanks, Robert Moss.
