[daip] aips disk access problem

[Chip Kobulnicky]

Hi,

I'm experiencing a problem reading data from aips disks.  

I have two machines, an SGI and a linux redhat 7.3 machine which
each have working aips installations and I'm having trouble sharing
disks between them...I think.  I've had the SGI for many years, and all
my data was processed and is visible from the SGI when I run aips.  The
problem comes when I try to access the same aips disk areas from my
linux machine.  I have the disks commonly mounted and accessible to both
machines (defined in DADEVS.LIST and NETSP and linked properly in
DATA/), and when I start up aips on linux, things look normal and
aips finds the disk areas ok.   I enclose the startup messages below.

But when I try to look for my data files which I see fine on the SGI I
get

> indi 2
> mc

AIPS 1: Catalog on disk  2
AIPS 1:    Cat Usid Mapname      Class   Seq  Pt    Last access     Stat
AIPS 1: ZFIO: OPER = READ LUN = 15 NREC =        6
AIPS 1: ZFI2: REQUEST FOR BYTES 5121 THRU = 6144 BEYOND EOF = 5120
AIPS 1: ZERROR: IN ZFI2   ERRNO = 22 (Invalid argument)

AIPS 1: ZERROR: IN ZFI2   ERRNO = 22 (Invalid argument)

What is this a symptom of?

If it helps, the linux aips is 31DEC02 and the SGI version is 15APR99.

Thanks if you have some clues,
Chip
