Re: z/OS equivalent to z/VM's Link Aggregation
Thanks for all the responses. I should have explained what z/VM Link Aggregation is. This is not about sharing an OSA port between multiple LPARs (that is easy). With a z/VM vswitch you can connect up to 8 OSA ports to a single vswitch. Turns out there is no direct equivalent in z/OS, you use VIPA. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: z/OS equivalent to z/VM's Link Aggregation
Ed, I think OSA acts like a switch, so you can share it between Lpars. I do use z/vm vswitch since we have only one processor on zpdt, but I have sen that in previous life.

Re: z/OS equivalent to z/VM's Link Aggregation
I don't recall the specifics but in Z/os you can define the OSA's and ports, and depending on the OSA-Express card you have, some have 4 ports per card, some have only 2, and if IIRC, on a z15 one for one, but you can share across LPARS defined in your IOGEN, and use a device / interface statement in your tcpip profile. we use virtual VIPA definition to manage the port usage if there's something specific you're looking to do, hardware or software let us know, that will let us focus on what you're trying to do Carmen On 12/8/2022 10:44 AM, Jim Elliott wrote: I am sure that z/OS must provide a function equivalent to z/VM's Link Aggregation (where you can share physical OSA ports in a VSwitch), but lots of Google searches are not helping me.

Re: z/OS equivalent to z/VM's Link Aggregation
Please explain a bit more what you are trying to do... Are you trying to share an OSA link with multiple LPARs? Are you trying to have multi OSA links for a single LPARs use like through a VIPA? A switch might not be needed. Also, what version of Z and z/OS Thanks -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
