> (BTW, why should PR/SM care what OS is to be run in the LPAR?) So it can know which one the IFLs can be given to? It was probably not using IFLs either since it was defined as MVS.

Re: IODF-HCD Defining FCP on a z9 for z/Linux
HI guys, I figured it out. There are two sections in the IODF, an LPARNAME and a CONFIG-ID For sanity I had the LPARNAMES and the CONFIG-ID the same. The CONFIG-ID is for z/OS and I think VM. It has no meaning in Linux. The CONFIG-ID is defined in option 1. In OPTION 5 you can associate Devices to a CONFIG-ID so you can select which Devices go to what z/OS (via the IPLPARM(LOAD**) All you need for Linux in the IODF is options 3,4,5 and no need to connect the devices to a CONFIG-ID.

As long as the chpids, CUs, and devices are configured to the VM LPAR (via IOCDS, HCD, or dynamic DEFINE), then CP (EDEVICE) and Linux (ATTACH or DEDICATE) can talk to the FCP adapters.

Re: IODF-HCD Defining FCP on a z9 for z/Linux
Both Linux and VM can talk directly to the channels so you don't have to define anything for Linux or VM in HCD OS config. As long as the channels, CU & devices are attached to the lpar Linux & VM can use them. -- Jay Brenneman -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
IODF-HCD Defining FCP on a z9 for z/Linux
I am trying to define FCP Channel, Controller and Unit so z/Linux native can use it. The LPAR that we are using for z/Linux is defined as MVS. HCD does not allow me to attach FCP units to an MVS LPAR. If I define a new LPAR as VM and it allows me to attach it. In order for z/Linux native to use FCP does the LPAR OS TYPE have to be defined as VM so I can attach the FCP Units to it or does z/Linux talk directly to the FCP channels?
