Thanks for the quick reply (and welcome to the land of z :)) I did not try run level 1. What I did try was logging off, DETACHing the DASD from SYSTEM, ATTACHing it to another Linux (two actually, both a SLES and a RHEL) and trying to mount the root file system. The other systems were not able to mount /dev/dasd1. Curious - so maybe SE Linux was an effect and not the cause. I do not have time to debug, so I commented out the two DASD, grabbed two more DASD for minidisks 100 and 101 and updated the user directory entry. I reinstalled 6.2 onto the new disks *remembering to first start a root shell and dasdfmt the disks* (that is something I forgot to do the first time and had to do later after the first intall failed). Let me digress and say that this is an issue we've been trying to get fixed for years. It is mentioned on p 119 of the RHEL 6 Cookbook ( http://www.redbooks.ibm.com/abstracts/sg247932.html) with the following words: Important: If the minidisks 100-102 (dasdb-dasdd) have not been formatted for Linux by dasdfmt before this installation, you should see the window shown in Figure 7-5 on page 118. However, there is a known issue in RHEL 6 where this window does not open and you do not have the ability to format the disks through the installer. If you proceed without formatting the disks with dasdfmt, the installation process will fail later. If this is the case, perform the following steps: ... There was a bugzilla opened for this in RHEL 6, but I don't have the number handy. Brad knows about it and almost had it fixed in the Anaconda python code. If you can re-open it at Red Hat, that would be most appreciated. (sorry, don't mean to dump on you so soon :)) I'll follow up with more info on the can't login/SE Linux issue later. I did see two 3390-9s in /proc/dasd/devices listed as both 7042 and 7043 MB. I'm now wondering if forgetting to dasdfmt the first time is the cause of this problem. Again, welcome to system z - it will be good to have a Red Hat rep on the list again.

On our > system, the first real IFL is CPU 02 (00 and 01 are the CP's). No. A z/VM *mode* LPAR on a z10 or zEnterprise has separate pools of CPs, IFLs, ICFs, zIIPs, and zAAPs at its disposal, depending on what's in the LPAR activation profile. By placing the "IFL" keyword on DEFINE CPU, you tell CP to use a real IFL out of the pool when it dispatches the guest. The guest could be dispatched on any available IFL. If you SET CPUAFFINITY OFF for the user (default is ON), all of the virtual CPUs will be dispatched on the "primary" CPU type (CP's for a z/VM mode LPAR). And Ray is correct - in a z/VM mode LPAR you need COMMAND SET VCONFIG MODE LINUX first. Look at the table in the DEFINE CPU command. (VCONFIG MODE ESA/390 is the default for non-Linux-only LPARs.) The relationship between the LPAR *mode*, as defined in the image profile (ESA/390, Linux, z/VM), and the valid primary and secondary CPU types is part of the machine architecture and is important to understand. It can seem a little strange until you realize that the purpose of this part of the architecture is to ensure that an LPAR's CPU configuration (a) is useful, (b) avoids abends, and (c) ensures workloads run on the CPUs they are licensed for. The SET VCONFIG command simulates the LPAR configuration mode and so the virtual CPU configuration is dictated.

I was wondering how you turn on each of the offerings. I have looked in several manuals and they talk about and compare the CMM offerings, but they were not specific on implementation. We load the CMM module via /etc/sysconfig/kernel MODULES_LOADED_ON_BOOT="vmcp cmm" So what is it that we have turned on?

If the folks at IBM think that CMMA was worthwhile enough to implement, then I'll drink their Kool-Aid and be happy with it. Especially since CMMA is so much easier to manage...just turn the blasted thing on. And it just makes sense for the two OSes to "actively" communicate page states rather than the not-so-dynamic method of CMM-1.

It is zfcp. No we do not have NPIV turn on since we just upgraded the SVCs this week (and the old one did not support NPIV (IBM 2145 firmware v3) and the new SVCs are loaded with latest V4. We will have the same issue of access once we move the LPAR z/Linux under z/VM.

Re: Help needed adding LCS Ethernet on a z9 for z/Linux LPAR (NO VM)
For some reason I am not getting any e-mail from my own posting. I get all other Linux-390 postings. I had to go to the Linux-390 index to read them. In response to Ursula Braun, lscss did not show F100-F101. Modules cu3088 and lcs loaded since I already have F200 LCS Ethernet working. Here is what I did to fix the issue. I finally got F100 to work by defining an OAT and then configing off CHP(F1) and then back online. It added it as eth0 and dropped the existing F200 connection (ifconfig showed it online). I just did an "ifdown eth1" and "ifup eth1" I was using LCS because?... Well. LCS was familiar to me and I did not know that QDIO could be shared until last 2 weeks. I am in the process of converting the LCS to QDIO. That is why I wanted to add the F100 so I could be logged on to z/Linux and delete F200 and then load the new IODF and then add F200 back as QDIO.

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.
