Re: Update z/VM 5.3 to z/vm 5.4
thanks Kris, Iam review the manual for details. Thanks again...for the moment ATTE Victor Hugo BBVA CCR America 2009/8/24 Kris Buelens kris.buel...@gmail.com You install the new VM release, can be done under your existing VM. Then you take over your own stuff from your old VM and integrate it in the new VM. If you use VM only as host for guests (like Linux), most of this work is taking over the CP directory definitions of the guests. The installation manual should help you. It can be found here http://www.vm.ibm.com/progdir/ z/VM V5.4 Guide for Automated Installation and Service 2009/8/24 Victor Hugo Ochoa vhoa...@gmail.com I have a question…. What is the procedure to follow for update environments z/vm 5.3 to 5.4. Exists some manual or some RSU for this purpose? Thanks to all ATTE Victor Hugo Ochoa Avila -- Kris Buelens, IBM Belgium, VM customer support -- Victor Hugo Ochoa Avila z/OS z/VM systems programmer Mexico, City.
Re: IFCONFIG to -REMOVE a link
Thank you Miguel, That did it. Shimon, Stop the interface with IFCONFIG VSECM DOWN first. It turns out that IFCONFIG doesn't use the actual device status to decide whether an interface is UP or DOWN...it considers a device UP if it has usable routes (i.e. it can actually send traffic). We should probably change that :-) Regards, Miguel Delapaz z/VM Development

Re: DDR and CPFMTXA commands
This is in the beginning of the CP Utilities Chapter that might be of interest.. Privilege class: if applicable, identifies the users able to issue the utility or the implied privilege class because of privileged diagnose codes.

TCP/IP Hangs?
We notice fairly frequent occurrences of a momentary hang condition. We see the x-clock in the lower left corner of the terminal emulator screen.

Re: TCP/IP Hangs?
A network trace between your IP address and the TCPIP stack is an excellent place to start. Looking at the packet trace will tell you whic h end of the connection is causing the delay. It could be delays caused by conflicts between the TCPIP algorithms for Nagle and Delayed Acks (which can be intermitten based on the packets tha t need transmitting). Been there, debugged that. It could also be a problem on the PC if Windows is doing paging. Been there too.

Stand-alone IPL of a Virtual tape
We are starting to implement a virtual tape system in our VM system; they are planning to get rid of our silos. To us, it is a black box; the zOS guys say just mount these volumes on these tape devices; treat them like real cartridge on real 3490 drives and you're good to go. I've tested the volumes devices using RMSMASTR, VMTAPE, VMBACKUP, DDR and for the most part, they work well. My question is: Recovery process usually starts with a stand-alone program, like DSF or DDR. If we have to IPL a stand-alone program like DDR that happens to be in a virtual volume onto a bare LPAR, how is this done? Thanks for any info. Ismael
Re: Stand-alone IPL of a Virtual tape
Ismael, You can issue the mount command from another LPAR. If the other LPAR is z/VM, this can be a VMTAPE MOUNT or DFSMSRM MOUNT command. If you have only one z/VM LPAR, then you'll have to issue the mount from z/OS. I don't know the command for that. Another option is to have a small system on disk that can be used to recover your main system. Normally, you would maintain the small system as a guest of your main system, but you would configure it so that it can also be IPLed first level. If you have to recover your main system in its usual datacenter, just IPL the small system and start your restores. For disaster recovery, you could backup and restore the small system using full volume dumps from z/OS. Note that this works for restores, but not standalone dump. For standalone dump, you need to have another LPAR available to IPL the small system. If you IPL it in the LPAR that you want to dump, the IPL will destroy the data that you want to dump.
