SUMMARY: DS20e consol and EVA disks

Hi!

The below problem was not solved until HP changed the motherboard of the
DS20e. Noone knows what actualy went wrong, but by testing several
interfaces, systems, arrays, zoning configurations, wwidmgr commands and
firmware version combinations the problem was isolated to the system
itself.

Thanks for numerous suggestions. When things dont go after the book, its
a good help to know we havent missed out something stupid.

We have run into a problem with DS20e and EVA3000. In consol mode the
wwidmgr can see the EVA controllers, but not the presented disks:

Consequently it is not possible to boot from the EVA.

If we boot Tru64 from the installation CD the OS can see the disks. So it is
not the presentation or zoning that is the problem.

We have tested KGPSA-C, FCA-2354 and FCA-2384 with different firmware
combinations and zoning shemes. In the above examples a KGPSA-C and
a FCA-2354 is installed. The FCA-2354 and FCA-2384 works fine with
a DS10.

The DS20e in question have lived happily with, and booted from, a
EVA5000 via the KGPSA-C in its younger days.


Any suggestions?


TIA
