Pat I don't know exactly when the requirement for the PORTNAME to be the same came in but it was before I worked first with OSA QDIO in 2001. See my response to Gadi.
However, you clearly remembered *something* recent so I dug into PORTNAME in System z9 and zSeries Open Systems Adapter-Express Customer's Guide and Reference. I found the following: <quote> 1.1.5.8 Port name relief For OSA-Express features running in QDIO mode, the port name identifies the OSA port for sharing by other operating system instances. When the port name is defined, all operating system instances that share the port must use the same port name. Beginning with a particular level of OSA-Express Licensed Internal Code (LIC) and some operating systems, this restriction has been lifted. A port name is not required at the following OSA-Express LIC levels and operating system levels: - z800 and z900 with OSA-Express (LIC) level September 2003 or higher - z890 and z990 with all levels of OSA-Express LIC levels - z9-109 - z/VM 4.3 with APAR PQ73878 and z/VM 4.4 - Linux -- V2.4 kernel June 2003 stream and above -- V2.6 kernel April 2004 stream and above z/OS, VSE/ESA, and TPF require a port name, which must be the same when the OSA port is shared with the same operating system in different images or in a mixed OS environment. In addition, the port name must match the device name. </quote> In a sense this is the opposite of what you are saying. <g> Chris Mason ----- Original Message ----- From: "Pat Schlehuber" <[EMAIL PROTECTED]> Newsgroups: bit.listserv.ibm-main To: <[email protected]> Sent: Monday, 08 January, 2007 7:28 PM Subject: Re: Sharing OSA in QDIO mode - TRLE question ... At some point in the last year or so, IBM did make a change that requires the PORTNAME to be exactly the same on all LPARs accessing the OSA. You end up getting a really odd IP message when you try to use it otherwise. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
