Re: IBM zEnterprise System announced???
LOL. I was trying to say that to me it seems like the zBX will (at least initially) be directed at adding some functionality (or maybe even offload because of that pesky sw bill issue that ziips and zaaps try to fix) to z/OS only. The Smart Analytics Optimizer is an example of that. One could think of other "appliances" that might be of use to z/OS. Sounds like it will be talking over that private IP network rather than some sort of CP co-processor though, so anything is possible.

So true, Barton."nothing to see here...move along" :-) I'd like more technical details on how workloads running on zLinux can be integrated with supporting processes running on the blade Linux. can a zLinux process control a blade server Linux process directly and if so, how?

Re: IBM zEnterprise System announced???
Alan, are you trying to make this announcement so totally boring on purpose? Just business as usual? nothing really new and exciting?

Stephen: The management functions in zBX and URM depend heavily on interfaces to the hypervisor and the operating system. With PowerVM and KVM, and AIX and Linux, those interfaces can be added. With MS Windows, this is a more difficult exercise. We are working on it, but don't expect MS Windows in the ` near term.

IIRC, SLES 11 activates DASDs during installation in the order provided manually by the user through the YaST UI or in an autoyast configuration file. Only during installation, it arranges for /dev/dasdX device names to have a predictable order and thus being able to use those kernel device names for partitioning during installation. In the installed system, DASDs (or zFCP LUNs or network devices) are activated by udev rules /etc/udev/rules.d/51--.rules. Since udev executes rules in parallel, the ordering of all those 51-rules cannot be predetermined. Therefore, you should use persistent device names to reference, e.g. DASDs, instead of their kernel device names /dev/dasdX. Symlinks such as /dev/disk/by-path/ccw- work well to reference DASDs by their devno. YaST can be told to use this as identifier for partitions in /etc/fstab and IIRC by-path is the default in SLES 11.

" I don't know jack about TSM, but based only on that quote and this thread so far I have to wonder what happens during a restore. If it's using compression to deal with sparse files, it's probably still compressing all those empty blocks, right? So on restore, does it decompress them and write blocks of zeros out instead of re-creating a sparse file? If that's the case, then it will still try to restore that 26GB sparse file to use 26GB of DASD, even if it compressed it down to 200MB on the server because of all the blocks of zeros in it.

Re: IFL's, VM, and Linux
Thank you for the clarifications. The VM LPAR in question is also running a z/OS guest hence the need to allocate the real CP's. From the HMC profile perspective, all the engines are shared among all the LPAR's. Re John S.'s question, we used the VM performance toolkit to observe a WAS/Linux workload and could see the work only dispatching on the CP's. I will report back when we get more info. Thank you all for the assistance.

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.

Re: IFL's, VM, and Linux
Ed, I think we need to look at your configuration a little deeper. You say that Linux can see all 6 of your real processors. By default VM will give just one virtual processor to a guest. How are you determining that you can get to all 6 processors with Linux? I think you will need to start by looking at the hardware Image profile to see what processors are assigned to the VM Partition? Under most circumstances most customers do not mix the CP's, IFL's and ZAAP's in the same partition unless they are running a VM Mode partition with z/OS as a guest of VM.

In the USER DIRECT entry for the guest, add COMMAND DEFINE CPU 00 IFL If the Linux system is not consuming more than ~ 80% of a real CPU, it should only have one virtual CPU defined. If it really needs more than that, then add another COMMAND DEFINE CPU xx IFL statement for each one. For this to take effect, you'll need to shutdown the Linux guest and log it off. You could issue the #CP DEFINE CPU 00 IFL command instead, but make sure your Linux guest is all the way down, as it will cause a virtual machine system reset and clear.

How can I tell Linux to use IPv4 before IPv6 for DNS resolution?
I have been asked several times by our network people if there is a way to get Linux to stop using IPv6 DNS resolution. With multiple search domains, Linux will try all of them in IPv6 before it tries IPv4. Especially when considering the IBM WebSphere is excessive with its use of DNS lookup, this results in a huge amount of useless network traffic. We need to tell Linux to try IPv4 lookup before IPv6. Has anyone found a way to do this? Most of our Linux guests are currently SLES9 with a few SLES10. We will be migrating to SLE11 soon so a solution at any of these levels will get us headed in the right direction. I think that I recently saw a similar question asked either on this list or on some other forum. I cannot find this discussion. I would appreciate it if someone could point me to the previous discussion.
