[daip] possible 31DEC04 bug related to reading TAPE

[Neeraj Gupta]

Dear Eric,


     I tried using AIPS' frozen version 31DEC04 on the Linux PC with OS 
Fedora-Core 3.  I noticed following two things:

1) In the script install.pl that comes with 31DEC04, $myvers = "31DEC05". 
Please change this to "31DEC04"

2) I also tried a small data analysis exercise.  Everything worked fine 
except for reading a tape with the FITLD.  The data was written (and then 
read also as a check) onto the tape using 31DEC03.  The 31DEC04 FITLD, 
REWIND however gives the error:

>mount
AIPS 1: Mounted on ANSI SCSI 2 tape on host genpro
>rewind
AIPS 1: ZTPOPR: REMOTE TAPE SYSTEM RETURNS ERROR CODE     99
AIPS 1: ZTPOPN: REMOTE OPEN ERROR  99 TO genpro
AIPS 1: TAPIO: ERROR  99 OPENING FILE
AIPS 1: INVALID TAPE

bharan> FITLD1: Task FITLD  (release of 31DEC04) begins
bharan> FITLD1: Reading tape drive number   1
bharan> FITLD1: ZTPOPR: REMOTE TAPE SYSTEM RETURNS ERROR CODE  99
bharan> FITLD1: ZTPOPN: REMOTE OPEN ERROR  99 TO
bharan> FITLD1: TAPIO: ERROR  99 OPENING FILE
bharan> FITLD1: ERROR      8 OPENING TAPE
bharan> FITLD1: Purports to die of UNNATURAL causes
bharan> FITLD1: bharani      31DEC04 TST: Cpu=       0.0  Real=    3


      I checked same tape, tape-drive with 31DEC03 aips.  It works fine. 
Also, I tried 31DEC03 and 31DEC04 compiled on RedHat9.  Again 31DEC03 
works fine and 31DEC04 gives the above problem.

    At this point I am stuck and need your guidance.



cheers,
neeraj
