I have some experience with the FAStT200 (3542) and my experience tells me
that you have not properly configured the 3542.
By default, the system type for the FAStT200 is set to Windows. You need to
make sure that the system type is set to AIX. This is mandatory.
Also, you need to delete the access volume on the FAStT200, which shows up
as LUN 31 in the output below. I think if you make sure that the system
type within the FAStT200 is set to AIX and you delete the Access Volume that
the FAStT200 creates, you should be good to go.
Additionally all the FAStXXX guides will tell you the same thing I'm telling
you.
I hope this helps.

Brian,
- plan a service outage
Then:
- umount Filesystems
- varyoffvg VG
- rmdev -dl hdisks
- look whith lsdev -Cc adapter at your fcs Location Codes
- look whith lsdev -C |grep Location Codes (for later remove)
- rmdev -Rdl (all dar-devices)
- rmdev -Rdl (all fcs-devices)
- cfgmgr (this will configure your fastt devices)
- look with fget_config -Av at your Fastt-Array (does it show what you
want?)
Nope, it doesn't show the card in slot 2 (which is now fcs0/dac0):
bash-2.04# fget_config -Av

This didn't work. varyonvg did, however.
- mount your Filesystems
We're changing several times Fastt-Storage from one machine to
another. If you go through like described above no problems will
occur.
I did it a couple of times, and the last time I ran cfgmgr -v and Some
things had a non-zero return code:
Completed method for: pci0, Elapsed time = 0
return code = 73
--
Completed method for: pci2, Elapsed time = 0
return code = 73
--
Completed method for: fcs0, Elapsed time = 10
return code = 73
--
Completed method for: fcs1, Elapsed time = 20
return code = 73
--
Completed method for: fscsi1, Elapsed time = 23
return code = 73
--
Completed method for: fscsi0, Elapsed time = 23
return code = 73
At one point (when all this started happening) I got a pci wrap error -- but
only one time. It looks like there may actually be some pci issue...
