Hello everyone,

I've got a LPAR with two different kinds of FC-Adapters (p690):
one 6227 (aka LP9000) and three 6239 (aka LP9802).

We are running AIX 5.2 ML2 and are about to install
a TSM-server on that LPA with its hdisks on a 2105-800 (ESS).

Well, due we've got those different adapters, I've got some questions and
maybe someone can give me some hints (due our IBM technican is not
reachable).

1. Do these different adapters interact with each other (or are there any
known problems?)?
2. Do the 6239 interact well with 2109 FC Switches (MC-Level 3.0.2.g(f) ??
3. Do I need a specific AIX level or any APAR (can not find anything on
IBM.com that says so, but you never know, ...) ?
4. How does SDD handle these different adapters ??

Thanks for any advice in advance

Regards
Peter Feldmann

I've got about the same issue. I have one P690 with a mix and one
with just the 6239 adapters. I haven't run into any problems with
2105-F20 or 2105-800 Sharks, or with 2109-F16 or 2109-F32 switches.
SDD doesn't seem to care. I haven't defined a single LPAR with a mix
of adapters, but I doubt it'll cause too much problems. I didn't even
know they were different part numbers until the vendor pointed it out
to me.

The P690 with the mix of adapters was running on the 6227 adapters,
and we added the 6239 adapters to it. It runs in full system
partition mode so it sees both adapters, but I'm only presenting luns
to the 6239's at this time. We'll LPAR that box later this month.
Oh, and it's running AIX 5.1 ML4. The other box is running AIX 5.2
ML3.

SDD doesn't talk directly to the hardware as such, it talks to a
device driver, so if AIX supports the card, SDD will just get on with
it's job.

Running cfgmgr will tell you if you have the right device drivers for
the cards, if you get no messages, then you already have the right
drivers.
