Re: if is possible
Loopback file systems are still supported
and available (even in HP-UX 11.31).
Example:
# mount -F lofs /usr/sbin /tmp/sbin
More details in mount_lofs(1M).
This creates "additional" file systems but not
LUNs or physical volumes, so LOFS is not going
to help you.
If you want to do some load testing, refer to
several other references in this forum that
discuss various tools for it (some free
and some commercial).
Cheers,

Re: if is possible
it is more similar to the --bind option available in linux. But there seem to be nothing like losetup.
you can use losetup to make files(usually sparse files with very large holes) appear as block devices in /dev/ which can be used by LVM.

Re: if is possible
You still need a iSCSI storage server for this. The HP-UX iSCSI software is available only in initiator mode and NOT in target mode. At least I have not seen any iSCSI software to allow iSCSI target configuration in HP-UX.

Re: if is possible
What exactly are you trying to do with that many LUNs on your server?
