We encounter difficulties while we make use of our tape-reader on a VAX-750 under UNIX BSD-4.3 operating system. When we are writing or reading files (which size is greater than about 200 K bytes) on or from the tape, we get the error message : +------------------------------------------ | ts0: hard error bn2020 xs0=350<6> | xs1=100000<6> xs2=100000<6> xs3=40<6> +------------------------------------------ This error happens as well as in multi-user as in single-user mode. It doesn't seem to be a problem of priority of the boards, nor a hardware problem. Small files can be read or written without problems. By another way, reading or writting from or to the tape work very well under UNIX BSD-4.2 O.S. (it is rather easy to switch from one version of the operating system to the other) We have an UNIBUS on which are connected : - 2 disks RA80 and RA81 thru UDA50 controller - 1 disk RLO2 thru RL11 controller (not in use) - 1 NP100 board for Ethernet - 2 DZ11 boards - 2 DHU11 boards - 1 DMF32 board - 1 DR11-W to connect a GRINNEL - 1 tape-reader M890-II (Cipher) thru TC12/FS (TS11 compatible controller) This is our configuration file to build the UNIX's kernel : +------------------------------------------ | # | # LIFIA VAX | # SWAP SUR RA80 ET RA81 | # | machine vax | # cpu "VAX780" | cpu "VAX750" | # cpu "VAX730" | ident LIFIA | timezone -1 dst 4 | maxusers 25 | options QUOTA | options INET | options "TCP_COMPAT_42" | options NS | options IMAG | | config ravmunix root on ra0 | config vmunix root on ra0 swap on ra0 and ra1 | | controller uba0 at nexus ? | controller uda0 at uba? csr 0172150 vector udintr | disk ra0 at uda0 drive 0 | disk ra1 at uda0 drive 1 | controller hl0 at uba? csr 0174400 vector rlintr | disk rl0 at hl0 drive 0 | device dz0 at uba? csr 0160100 flags 0xff vector dzrint dzxint | device dz1 at uba? csr 0160110 flags 0xff vector dzrint dzxint | controller zs0 at uba? csr 0172520 vector tsintr | device ts0 at zs0 drive 0 | device dmf0 at uba? csr 0160400 flags 0xfc | vector dmfsrint dmfsxint dmfdaint dmfdbint dmfrint dmfxint dmflint | device dhu0 at uba? csr 0160500 flags 0xffff | vector dhurint dhuxint | device dhu1 at uba? csr 0160520 flags 0xffff | vector dhurint dhuxint | pseudo-device pty | pseudo-device loop | pseudo-device inet | pseudo-device ether | device dr0 at uba? csr 0172410 flags 0x1 vector drintr | # | device np0 at uba? csr 0162000 vector npintr | # | pseudo-device gmr | # +------------------------------------------ Thank you for any help...
