HP filesystem on IBM AIX

[Victor BERRIDGE]

You may have hit the nail Mark!
Quite right AIX seem to have trouble with negotiation so IBM recommend to fix the speed... and I had to do the same on all the HP after because the switches went bezerk...

There may very well be some lan config mismatch

All the best

I had the AIX FS mounted on the HP to do the copy to the AIX FS and this was slow.

So I change to mounting the HP FS on the AIX server and it is much faster.
This puts AIX in control of it's own filesystem for creading directories and files.

Also very different to mount an NFS in AIX.

I had checked the NIC's and they were both 100FD on the same switch.

Thanks for all of the responses.

I think it would be better for You to simply debug and resolve the NFS/Network issue You encounter than to try anything else.

I can come up with a few weird ways for potentially accessing the HP-UX disks, some of which might even work, but it's nonsense :)

For Your information:
I have an old RS/6000 which will easily deliver >10MB/s for NFS transactions.

A small checklist:
- Are both nodes showing use of NFS version3?
- is the performance close to line rate when using ftp for a test file transfer?

if the ftp transfer shows high performance, debug NFS settings, if ftp is also slow, check network parameters and connection.
