On your HP-UX 10.20 machine try increasing the value
of the kernel parameter STRMSGSZ. This value is set
to 0 on our 10.20, and to 65536 on our 11.0 machine,
so this maybe the reason for ENOBUF errno you're seeing
on your 10.20 machine.
Regarding the recent "insufficient memory" postings:
The default data segment limit of HP-UX is 64 MB per process,
so when dsmc runs on rather large file systems, it may hit
this limit. This limit can be increased by modifying another
kernel parameter (this procedure is going to be documented
in the HP client README that's going to be shipped with the
next ptf):
1. As root user, start "sam".
2. Select "Kernel Configuration"
3. Select "Configurable Parameters"
4. Locate "maxdsize" and increase its value through the
menu entry "Actions/Modify Configurable Parameter...",
e.g. set it to 268435456 for a 256 MB max size of the
data segment.
5. The kernel gets rebuilt by sam after this change and
the system needs to be rebooted for the new setting to
take effect.
