I seem to remember that IBM OS's need a SAN that
will talk ESCON or FICON and will resent emulated 3390 disks.

Thanks for the info Dave, I have learned what can and can not be
installed over FCP (aka SAN) via this page:
http://www-03.ibm.com/systems/z/hardware/connectivity/products/fe8.html
# CHPID type FC ? FICON, zHPF, and channel-to-channel (CTC) traffic for
the z/OS, z/VM, z/VSE, z/TPF, and Linux on z Systems environments
# CHPID type FCP - Fibre Channel Protocol (FCP) for attachment to SCSI
devices for the z/VM, z/VSE, and Linux on z Systems environments
So now we know what can and can't IPL over which interfaces, now its a
matter of finding which devices support what.
I think the IBM TotalStorage series of disk arrays support FC, at-least
DS4000 and up, DS3000 may but I am not sure.
I have found some DS4000 chassis up which are somewhat cheap but then I
need to buy caddies and drives and that will add up...

I have found complete DS4000's for around 200 dollars.
http://www.ebay.com/itm/IBM-DS4000-EXP100-SAN-Expansion-Unit-1724-1xp-w-14x…
But still I am not 100% sure they support FC, and are not just SAN's
over FCP which I think they also support.
To say the least I need to find someone very familiar with the newer IBM
hardware because I don't want to pay as much as I did for the machine to
get storage that 'might' work.

Not sure. I think LINUX
will run with Network Attached Storage ....
Congratulations! Mainframes are fun!
Thanks and yes they are :)
One does not boot a mainframe; one IPLs it. :)
I totally knew this but somehow forgot such terminology while writing > I can't advise you as to the other boxes.
From my Linux experience on
mainframe I can say it doesn't seem to boo... IPL
any differently to any other
mainframe OS. If you can define the device to the mainframe and issue an
IPL command, you *should* be able to IPL anything I think? Hm ok, I
will have to do some more research on the storage front then.
What I have been told is that you can IPL Linux over a SAN but not any
IBM OS.
But if IPLing shouldn't be any different then
maybe you can't IPL from
a
SAN at all which I wouldn't be surprised at. -Connor K
Check the OS defaults of the SAN networking software layer. My instinct is
AIX might play a part here.
