>I received several useful responses which allowed me to get the
Fibre
>Channel adapters to work.
>
>I ended up changing the card slot and upgrading to v5.0a. The
system boots
>properly and v5.0a adds a FC utility called "emxmgr" which gives
the ability
>to configure the FC adapters and provides substantial connection
info.

>The original questions:
>
> > The first question is: Does this hardware support
Fibre Channel?
> > Next being: Can it be made to work?
> > I have an AlphaStation 500 running v4.0f with the
latest patch
>cluster and
> > Console V7.2.
> > I have both a KGPSA-BC (Emulex LP7000) and a
KGPSA-CA (Emulex
>LP8000) that
> > I > have been working with. When either card is
installed Tru64

/usr.
> > At the console prompt I have tried running wwidmgr
and the command
>is not

> > My suspicion is that Fibre Channel is only
supported on servers

AlphaServer? Which

>As far as failing to boot:
>AlphaStation 500s have the obnoxious feature that the bottom PCI
slot has a
>lower ID number than the motherboard's SCSI host adapter. When you
put a
>SCSI host adapter in that slot, the motherboard SCSI changes from A
to B,
>which also changes the name of the SCSI bus as seen by the
operating system.
>This change causes problems when booting a system disk that was
created when
>the bottom slot was empty: it'll load the kernel and then fall
over, since
>the entries in /etc/fstab are suddenly wrong.
>
>While I wasn't using the bottom slot I tried a different slot and
"presto".
>I could finish booting.
>
>And wwidmgr via server firmware:
> I don't think it would be wise to try and load firmware for
a
>different system on the workstation. You might end up with a large
bookend.
