Jim,
I know I've banged on about this before, but I can't stress enough just how
useful taking a (SYSTCPDA) packet trace during your problem period (even for
just a minute or two), using IPCS to convert it to SNIFFER format,
downloading it to a PC and feeding it into Wireshark (www.wireshark.org)

FWIW, in my infrequent looks at RMF reports, OSA utilizations never seem to

This is a stupid question but we need to analyze the use on one of our OSA
CHPIDs. Anyone who actually know anything about it is out of the office so it
has fallen to me to look into it. I can tell it's not as simple as just Bus
busy or Channel busy, or Read bytes and write bytes but I'm

Thanks, Hal. We have opened a ticket with IBM. I'm using IBM-Main to see if I
can get more/better information faster this way.

Also, have you checked that the OSA is connected at the proper speed and
duplex? This can be done through the HMC.

So, this is a Gigabit OSA? If so, 100MB is close enough to theoretical
maximum data rate that it's pretty safe to say it's maxed out.
