This is a bit unrelated to your questions but one major difference between the OSA2 and OSA3 100-Base-T card is that if you define a port on the OSA3 as an OSC channel for use as an OSA-ICC, then the second port on the card is disabled and will not be used as an OSD or OSE type device. Basically, one port will be wasted.
Aria From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of Mark Pace Sent: Thursday, April 01, 2010 2:30 PM To: [email protected] Subject: OSAExpress3 I hope someone can confirm for me the difference between OSA2 and OSA3. Next week I will be receiving a z10 to replace a z9. For the sake of simplicity lets say I had 1 OSA2. That would be 2 ports or 2 CHPIDs. On those CHPIDs I have 3 addresses each CHPID 1 100-103 - CHPID 2 200-203. Each CHPID is attached to a different network. So I know in TCPIP if I want to go to one network I use a specific set of addresses and if I want to go to the other network I use the other set of address. Now the z10 is coming. The OSA2 has been replaced with an OSA3 1000-baseT -2P. So now I have 1 CHPID with 2 ports. IF, and it's a big IF, I understand how it works, I can still create the 2 address ranges on the 1 CHPID. Port 0 goes to one network, Port 1 goes to another network. Then I use the PORTNAME parameter on the Device Statement to determine which network I want to get to. What I'm having a hard time with is now is how do I associate which port number is which PORTNAME. -- Mark Pace Mainline Information Systems 1700 Summit Lake Drive Tallahassee, FL. 32317
