Tuning an HBA Fibre Channel Tachyon TL/TS/XL2 A6795A model on HP-UX 11.11

First:

You might check the HP forums:

itrc.hp.com

Second:
For the emulex cards the former Clariion procedure generator contains the EMC recommended HBA settings. I generated one for HPUX but, the newest doesnt contains any settings.


Third:
Another useful docs is the fcsmutil man page. You can query the HBA parameters.

It doesnt contains too much settings, except the topology.

I know better the emulex cards.
For the emulex cards the the target queue depth influences the speed, but
in many cases it not so significant.

I think the correct Powerpath and Os settings better influences the performance.
(For example Powerpath policy, autotresspass settings)
