Re: HyperPAV and LVM striping
Tom, I agree 100% with you, in many cases, using LVM (with stripes) and PAV, we improve 100% of I/O capacity for a I/O intensive workload (eg. Oracle Database). One critical point in some cases, is that the LVM architecture is not fully supported by vendors (eg. Oracle RAC using LVM volumes in cluster filesystem based on ASM technology is not supported by RedHat, Oracle or SuSE). At this point, the best way is use only PAV technologies (HyperPAV, Dynamic PAV, Static PAV, etc..) with a large number of alias volumes and MDISK's on z/VM directory (to use a parallel access on these volumes). But, considering the I/O capacity and the facility to manage, I suggest the use of SCSI/FCP volumes, of course, if you want this option. Regards, Fernando 2012/10/10 Duerbusch, Tom duerbus...@stlouis-mo.gov Just speaking to LVM... Striping the data across multiple volumes (which in modern dasd is already stripped in the Raid array), would give you the best performance. Especially if you can strip across multiple DS8000 (or other dasd subsystems). But you can also use LVM as a pool of DASD, with no striping involved. In case 1, if you need to expand the LVM pool, it is a hassle. It might mean backing up, reformatting and reloading the data. In any case, it involves a knowledgeable person and most likely, downtime. In case 2, if you need to expand the LVM pool, you can just add disks to it on the fly (and even easier with VM). No downtime. I add dasd to my LVM pool in minutes. The trade off is normally (well isn't it always), performance vs man power. If you find you really don't need the BEST performance, then make the job easier. But then, I you know the requirements of your application. Tom Duerbusch THD Consulting On Tue, Oct 9, 2012 at 5:50 PM, Brad Hinson bhin...@redhat.com wrote: Hi folks, What are the best practices for HyperPAV and LVM striping? I assumed that if you have HyperPAV enabled, you don't need to stripe the data. Is this true, or if not, what is the best practice for optimum performance? I have lots of mod-9 ECKD with HyperPAV enabled, so I want to use LVM. So my two choices are standard LVM, or LVM striping. If I stripe across the disks I spread the I/O across the physical volumes, but my gut tells me I shouldn't have to do this, since HyperPAV is moving around aliases dynamically. For example, say I have 2 PVs and 4 HyperPAV aliases. If I send some heavy I/O through the Linux (device-mapper) block device, then I would assume: - #1, for the case with LVM striping enabled, LVM will spread the I/O to both PVs, and HyperPAV will assign 2 aliases to each PV since I'm banging on them both. - #2, for the case without LVM striping, HyperPAV will assign 4 aliases to the first PV since that's the only one in use. In either case, it seems I'm using all 4 aliases, so seems like I would get the same performance. Please correct me if I'm wrong. And if so, which of these configs is better? Lastly, is there a presentation or doc that talks about how to enable HyperPAV in Linux, or is bringing the HyperPAV aliases online enough to trigger the dasd driver to do the right thing?

The storage guy is saying that since the storage subsystem did not phone home, the disks are ok. thats a support question if ever I heard one. Contact SAP/IBM. (Which of course will lead to a question on maintenace levels of linux and sap.) Since we are having the problem right now, I contacted our SAP basis manager and requested that he contact SAP.

The kill did not work, so I did the shutdown command. I let it sit a few minutes. The normal shutdown sequence not complete. So I ended up doing a #cp logoff. were you alreday in shutdown?

Intel Chip Vulnerability
Hi Guys, Well, recently a vulnerability of Cache memory in Intel Chip was published. Sorry by off-topic message, but I think it is worth reading. Regards, Intel Chip Vulnerability Could Lead to Stealthy Rootkits By Brian Prince 2009-03-20 Security researchers have turned the spotlight on an Intel chip vulnerability that could allow hackers unauthorized access to system management mode code. The hack was disclosed recently by the efforts of two separate researchers, but was apparently first uncovered by Intel employees. Security researchers have released proof of concept exploit code for an Intel chip flaw that could be abused to compromise computer systems with stealthy rootkits. The attack takes advantage of an Intel CPU caching vulnerability that can be used to get unauthorized access to SMRAM, a protected region of system memory where the system management mode (SMM) code lives. Joanna Rutkowska and Rafal Wojtczuk of Invisible Things Lab released a paper with proof of concept code yesterday, while Loic Duflot, a research engineer for the French Central directorate for Information System Security, was slated to simultaneously make a presentation on the issue at the CanSecWest conference in Vancouver. Duflot and the researchers at Invisible Things Lab discovered the flaw separately - though apparently neither are the first to report its existence. According to the team at Invisible Things Lab, the flaw was actually found initially by Intel employees, who wrote about how this class of CPU caching vulnerability could be exploited back in 2005. The attack assumes the hacker has access to certain platform MSR registers. Technical details of the attack can be found here in the paper from Invisible Things Lab. Successful exploitation of the CPU cache poisoning allows hackers to read or write to SMRAM, which is otherwise protected. “The attack allows for privilege escalation from Ring 0 to the SMM on many recent motherboards with Intel CPUs,” Rutkowska, CEO of Invisible Things Lab, explained in a blog post. According to Invisible Things Lab, this marks the third attack on SMM memory they have found in the last 10 months affecting Intel-based systems. “Intel has informed us that they have been working on a solution to prevent caching attacks on SMM memory for quite a while and have also engaged with OEMs/BIOS vendors to implement certain new mechanisms that are supposed to prevent the attack,” according to the paper. “According to Intel, many new systems are protected against the attack. We have found out, however, that some of Intel's recent motherboards, like e.g. the popular DQ35, are still vulnerable to the attack.” In her blog, Rutkowska added that researchers should not be blamed for publishing information they find about a bug if vendors do not move quickly enough. If there is a bug somewhere and if it stays unpatched for enough time, it is almost guaranteed that various people will (re)discover and exploit it, sooner or later, she wrote.

Debian on System z
Hello Guys, Someone uses Debian on mainframe? I have something to go up automatically an interface OSA, in Debian. I changed /etc/network/interfaces and put the configuration of the new interface (hsi0). It also created the file /etc/sysconfig/hardware/config-ccw-0.0.0800 with the addresses of the device. When I give lsqeth command, the device appears, but no device name: Device name : - card_type : HiperSockets cdev0 : 0.0.0800 cdev1 : 0.0.0801 cdev2 : 0.0.0802 chpid : 00 online : 0 portname: no portname required portno : 0 route4 : no route6 : no checksumming: sw checksumming state : DOWN priority_queueing : always queue 2 fake_ll : 0 fake_broadcast : 0 buffer_count: 16 add_hhlen : 0 layer2 : 0 large_send : no I tried to search for something on the interface that already up automatically, but did not find anything significant. I wonder if anyone has solved this problem with Debian. I know I can put a clause in the pre-up /etc/network/interfaces and a script with echo 0.0.0800 /sys/ echo 1 x, but I would like to know if there is one less way to do this craft.

Re: Application Server for z/Linux
Use Jakarta Tomcat on http://tomcat.apache.org with IBM JVM on http://www-128.ibm.com/developerworks/java/jdk/linux/download.html Use Tomcat version 5.5.23 and IBM J2SE 5.0 SR4. First install IBM J2SE and later install TOMCAT. For Tomcat, download binary core distribution and deflate on /usr/local/tomcat. Declare and export JAVA_HOME, JAVA_BINDIR, JAVA_ROOT, CATALINA_HOME, CATALINA_BASE and CATALINA_TMPDIR variables. For more details see http://tomcat.apache.org/tomcat-5.5-doc/ It's work perfectly.

Re: LVM Stripes
Tanks Rob, You has all the reason. I wait to have helped. Fernando 2007/2/2, Rob van der Heij [EMAIL PROTECTED]: On 2/1/07, Fernando Gieseler [EMAIL PROTECTED] wrote: I have gotten up to 4000 IO/s in a SGBD Oracle 10G with a partition LVM with 128 Stripes in both the cases. With MD's and 3 partitions in 3390-3. High I/O rate is not by definition a good thing, considering that Linux can do anywhere between 4 KB and 800 KB in a single I/O. It might imply you break up your I/O's in 1 block per I/O (although with random read that may be your only option). With MDC by default doing track based cache, it would help you get the remaining 14 blocks out of MDC indeed. But doing more data per I/O would have given the same throughput with way less overhead in Linux and z/VM. If your 4000 is taken from Linux as 1K blocks per second then we're talking different numbers. That might translate to something like 100 SSCH's per second which would be less exciting for 3 FICON channels. And you're right. If you are happy with the configuration, there may not be a need to change it. But knowing whether that configuration would also make others happy is a different question.
