I'm absolutely a fool when it comes to this SCSI and AIX, but here is
what I've got; 1 Box (7025-F50), 3 Hard Drives (IBM 4.5G SCSI Part#
76H2697). In need of another hard drive, badly! I want to step into
the double digits of Gig's this time around (18, 36, or whatever).
>From what I can tell at a glance there appears to be an available slot
for one more drive. What I'm looking for is some simple suggestions on
makes/models, tips/tricks, whatever you can do to help me is greatly
appreciated.

Hallo Matt,

what you need is well descibed in 7025-F50 Users Guide

http://publib.boulder.ibm.com/infoce...ries/index.jsp

For more drives you need additonal hardware.
A SCSI backplane FC 6519, a SCSI cable FC 2144 and
of course a SCSI Disk hot swap FC 3104 (18 GB for example)

Thanks for the help. After reviewing the user's guide, I've learned
how to better describe my current situation. I've currently got one
SCSI Backplane connecting 3 4.5Gb SCSI hard drives (With carriers,
obviously), I've got what looks like three available slots on that back
plane for additional drives. My questions is thus, assuming I purchase
the appropriate carrier, I should be able to purchase any Ultra SCSI
drive, install it, and partition it to its full capacity, should I want
to? Also assuming I set the SCSI ID to auto, to avoid any unnecessary
conflicts.

Thank you for your help,
I ended up finding a store on ebay that is selling 9.1G drives
w/carriers for ~$100 ea. Going to just buy three more and fill up the
back plane and be done with it, I know I won't be needing to add
another backplane anytime soon, as we're only now starting to hit that
13.5Gb limit provided by the 3 4.5G, an additional 27Gb should keep us
sitting pretty for the forseable future.
Thanks again, and have a good day.
