If I remember correctly: the portname is defined by the first "user" opening the OSA, and, z/VM no longer requires a portname, but if another OSA "user" sets a portname it must be specified in Z/VM's TCP/IP stack too. If TPF requires a portname, select a name yourself, and code the same in TPF and z/VM TCP/IP
Here an extract from z/VM's TCPIP's manual: When the device is started and a PORTNAME has been specified on the DEVICE statement, TCP/IP will set the PORTNAME as the hardware adapter name. If an adapter name was already assigned by a previous connection, then the PORTNAME must be the same as the one assigned by any other connection in order to share the adapter. That requirement includes the OSA Express Adapter shared within a logical partition or with all other partitions. The PORTNAME is optional on the DEVICE statement. However, some levels of the real or virtual OSA Express adapters require the PORTNAME to be specified. When such an adapter is in use and the PORTNAME operand is omitted, an error message will be displayed during device initialization. 2008/12/28 Ian S.
