Unfortunately, the HP-UX iostat only gives KB/s transferred, Seeks/s and ms/seek per disk device
and not the detail the Linux implementation does.
If that doesn't suffice you would need Glance (which requires an extra license).
With Glance installed you can get virtually any system metric,
and you could write a so called Adviser script (shell like syntax) which you can run from a shell script on glance in adviser-only mode (i.e. not the usual interactive mode of glance).
However, with the network stats per NIC we have more luck.
On HP-UX you only use a different interface, viz. the lanadmin command.
So for instance to get the MIB counters of lan0 on this HP box I could issue
$ /usr/sbin/lanadmin -g mibstats 0
This produces lots of counters which I omitted here for brevity,
and which you will have to parse for interesting data.
Important is the final arg which is the so called PPA (physical point of attachment, HP's way of enumerating NICs so to speak)
To get an overview of which NICs are built into the box and supported by the kernel you can run
$ /usr/sbin/lanscan
or more tersely to take only active NICs into account
