Hi, I have had that tape drive and motherboard working hand in hand for many years without a problem. Lately it started to give messages like: on a amlabel command: Jun 27 13:02:10 amanda /kernel: (sa0:sym1:0:2:0): WRITE FILEMARKS. CDB: 10 0 0 0 2 0 Jun 27 13:02:10 amanda /kernel: (sa0:sym1:0:2:0): ILLEGAL REQUEST asc:50,0 Jun 27 13:02:10 amanda /kernel: (sa0:sym1:0:2:0): Write append error Jun 27 13:02:10 amanda /kernel: (sa0:sym1:0:2:0): failed to write terminating fi lemark(s) Jun 27 13:02:10 amanda /kernel: (sa0:sym1:0:2:0): tape is now frozen- use an OFF LINE, REWIND or MTEOM command to clear this state. Jun 27 13:03:18 amanda /kernel: (sa0:sym1:0:2:0): ERASE. CDB: 19 1 0 0 0 0 Jun 27 13:03:18 amanda /kernel: (sa0:sym1:0:2:0): ILLEGAL REQUEST asc:2c,0 Jun 27 13:03:18 amanda /kernel: (sa0:sym1:0:2:0): Command sequence error on a dd command: Jun 28 13:48:04 amanda /kernel: (sa0:sym1:0:2:0): extraneous data discarded. Jun 28 13:48:04 amanda /kernel: (sa0:sym1:0:2:0): COMMAND FAILED (87 0 1). But at same time I can do a tar without problem, I could write quite some amount of data during a backup at night... Error are consistant whatever new or old tape I use in the drive. Drive is SLR 100 from Tandberg sa0 at sym1 bus 0 target 2 lun 0 sa0: <TANDBERG SLR100 0402> Removable Sequential Access SCSI-2 device sa0: 40.000MB/s transfers (20.000MHz, offset 15, 16bit) SCSI adapter is Symbios sym1: <896> port 0xb000-0xb0ff mem 0xf8000000-0xf8001fff,0xf8800000-0xf88003ff irq 10 at device 5.1 on pci1 sym1: Symbios NVRAM, ID 7, Fast-40, LVD, parity checking sym1: open drain IRQ line driver, using on-chip SRAM sym1: using LOAD/STORE-based firmware. sym1: handling phase mismatch from SCRIPTS. Nothing has been changed in hardware and operating system lately. Any help or direction for diagnostic is warmly welcome Bests, Olivier
