How to create file of fixed size?

HP-UX does not /dev/zero nor mkfile. Modern versions of HP-UX have a command called prealloc which can do this. But I doubt that this command will exist on HP-UX 6.5. I'm pretty sure that will need to upgrade to HP-UX 7.0 before you will have this command available. 
I guess you can just cat several copies of a large file together to make your placeholder.
cat largefile largefile largefile > placeholder
Since your disks are only 571 MB this shouldn't take long.
BTW, I once lifted an enclosure with two 7937's and placed it into a shipping container.
Seriously, why are running a system this old?

mkfile
mkfile(1M) mkfile(1M) NAME
mkfile - create a file SYNOPSIS
mkfile [-nv] size [g | k | b | m] filename... mkfile creates one or more files that are suitable for use as NFS-mounted swap areas, or as local swap areas. When a root user executes mkfile(), the sticky bit is set and the file is padded with zeros by default. When non-root users execute mkfile(), they must manually set the sticky bit using chmod(1). The default size is in bytes, but it can be flagged as gigabytes, kilobytes, blocks, or megabytes, with the g, k, b, or m suffixes, respectively. -n Create an empty filename. The size is noted, but disk blocks are not allocated until data is written to them. Files created with this option cannot be swapped over local UFS mounts. -v Verbose. Report the names and sizes of created files. USAGE
See largefile(5) for the description of the behavior of mkfile when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes). See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ chmod(1), swap(1M), attributes(5), largefile(5) 2 Feb 2001 mkfile(1M)
