Hi

I have some problems with a SCSI tape

My configuration

  - board ADAPTEC AVA1505  Portbase 0x340  IRQ 10

      -> Kernel 2.0.32 compiled with SCSI device "aha152x"        
      -> lilo.conf option: append="aha152x=0x340,10,7,1"

  - Tape Streamer HP colorado T4000s

  - OK at Boot time
           
=>
>aha152x: processing commandline: ok
>aha152x: BIOS test: passed, detected 1 controller(s)
>aha152x0: vital data: PORTBASE=0x340, IRQ=10, SCSI ID=7, >reconnect=enabled, parity=enabled, synchronous=disabled, delay=100, >extended translation=disabled
>aha152x: trying software interrupt, ok.

It's now the problem

access at tape with "tar"

 a) with this command line : "tar -cvf /dev/st0 -i -W /home"
    ->  Backup OK but at last file with -W option
   ERROR
 
  > st0:Error with sense data: EOM Current error st09:00 sense key
  > illegal Request Additional sense indicates Command sequence error

and after few seconds  

  > tar : Read error on /dev/st0 : I/O error



unless "-W" option  Backup OK but an "append" (-r option of "tar" )same
kind of error

"tar -tvf /dev/st0" ok only with first part of backup

same kind of error with "/dev/nst0 (mixer avec diff. commandes mt),
/dev/rmt0 "

It's seems that was a error occurs when write the END-FILe symbol of
archive on the tape or some things like that ...

I hope that you help me

Best regards
