IBM NetFinity 4500R ipsraid
A client bought one of these on Ebay for $200.00. Not a bad deal
at all, 2 8 GB drives mirrored, plenty of RAM: just the thing to
replace an aging SCO 5.0.5 system.
But it turned into quite a struggle. First, he couldn't find
drivers. Well, he could easily find a page that listed drivers:
but couldn't actually download any. A manual ftp to the indicated
links turned up empty too; the images weren't there. Were these
removed, officially or unofficially, because of the SCO lawsuit? Or
was it just ordinary web site screwups where things have been
moved? I don't know, but I confirmed that these couldn't be
However, I knew darn well that they don't make different CD's
for every OS out there, so I went to http://www-3.ibm.com/pc/support/site.wss/MIGR-39729.html.
file there showed me that SCO BTLD images were on the "Linux" CD,
so I downloaded that and made a BTLD floppy from it.
You neeed to boot the NetFinity from that CD to upgrade the BIOS
and configure the array. That part went fine, but I was thrown off
by the the interface which kept referring to Controller 1 and Array
1. I would have assumed that was just renumbering for humans, and
that it was actually 0 and 0, but other IBM documentation showed
(incorrect) examples of
defbootstr link="ipsraid" Sdsk=ips(1,0,1,0)
so I tried that, with no luck. I was also confused by IBM
references to the ID that would be presented by the array.
Ordinarily, that's going to either take the lowest ID of its
members (in this case that would be 0), or it is something you can
specifically set. Well, nothing in the config allowed you to set
it, and I would have assumed it would be 0, but again documentation
seemed to suggest that it might be 1. After floundering around for
a bit, I realized that my instincts had to be right, so I used:
defbootstr link="ipsraid" Sdsk=ips(0,0,0,0)
which worked fine. This was one of those dumb cases where I
would have been better off if I hadn't read the docs.
