William, If the previous OS such as OS/390 had the OSA defined to it the portname will be specified by OS/390. Change your TCPIP defs for zVM to specify the original portname from the previous or other OS sharing the adapter. If the portnames match you can share the OSA adapter. I recently ran into this with zVM 4.2 in an lpar sharing the OSA with OS/390 v2.10. OS/390 had set the portname and zVM TCPIP could not open the adapter. I do not remember the original failing messages from zVM. Good Luck ....

I've asked and I'm told that no other system explicitly specifies a portname. I wanted to check this assertion. So we took one of the "failing" OSA adapters and gave it to TCP/IP on VM, which did initialize and successfully used the OSA adapter. Had OS/390 on another node specified a portname I would have expected that TCP/IP on VM would -not- be able to use the card. I'm not certain that this result is definitive but given what I read in the TCP/IP documentation for VM (which says the portname -MUST- match) I expect so. Thanks for the suggestion. Any other ideas would be appreciated! -----Original Message----- From: John P Taylor [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 29, 2002 12:44 PM To: [EMAIL PROTECTED] Subject: Re: OSA Is the VM system in an LPAR? If so and another system uses the GB ethernet adapter, which is IPLed before yours, then I believe that system would determine what the portname is.
