We are using OSA Express 3. Two OSAs on different chpids and on differen t NIC addresses. We separated the two OSA because we want the primary OSA to be used only for production traffic and the secondary OSA for Netbacku p backup traffic only. However when we perform the Netbackup backup of files, the primary OSA slows down or stalls until the backup traffic completes on the secondary OSA. I heard that there may be a bug that is causing one OSA disabled while th e other OSA is enabled and active? Possibly with OSA Express 3 and TCP Layer 2? I searched the IBM knowledge base and could not find a match or locate a fix. I am holding off on opening a issue with IBM for now, but will soon if I can't find anyone having or have run into the same issue. Any help would be appreciated. Thanks, Steve.

Best practice: shutdown the z/VM guest servers and even the z/VM system (since presumably it is being moved, too) during the backup. FDR can copy directly from disk to disk (presuming that the architecture is the same). Saves tape mounts and downtime. FDR has the capability to re-label the from volume when the copy has completed.

To reply to the David Juarez's post, and clarify Dave Jones' reply, Dave Jones' reply is correct. It just leaves off the dynamic memory change up to the mstor (16G in the example) available via the CP DEFINE STORage command. That dynamic change is gone the moment that userid is logged off, unless it has been matched by Dave's suggestion to update the user directory entry, presuming that a permanent change is desirable (not always the case). We've had instances in which more memory was required for a big app (read: Websphere, or Omegamon/XE) installation, but not needed after the software was installed. Permanently increasing the memory in such instances would be a bad thing, causing extra real z/VM paging and I/O.

How can we control how much CPU is used by each zLinux guest?
What controls can be put in place to manage zLinux guests running under z/VM 5.3, so they do not saturate CPU and memory? Does the USER MSTOR parm really limit the zLinux guest to the amount coded? Thanks. David T. Juárez IT Specialist
Cost accounting for Linux guest running under z/VM
We are in the process of getting ready to add production Linux guest and we need to know how you are charging back the customer for running Linux under z/VM. We currently charge a fixed fee per month for small, medium and large based on the size of the individual server's memory, cpu, and network connections. Any ideas would be greatly appreciated. Thanks. David Juárez Department of Veterans Affairs IT Specialist - z/OS and z/VM Systems Programmer 512-326-6116
Linux guest not seeing mini disk
We are running z/VM 5.3 with Red Hat Linux 5. We have created a new guest and defined in the user directory some mini disks as follows: USER LIN0003 KK 2G 2G G INCLUDE LNXDFLT OPTION APPLMON MDISK 100 3390 0001 3338 VM7DBF MR MDISK 691 3390 0001 200 VM7DC0 MR MDISK 692 3390 0251 3038 VM7DC0 MR MDISK 693 3390 3289 3338 VM7DC0 MR MDISK 694 3390 6627 3389 VM7DC0 MR When we logon to the linux guest and issue #CP Q V DASD we get the following output and everything looks good.

Is there some definition in Red Hat Linux 5 we need to make? Thanks in advance for any help. David T. Juárez IT Specialist
Oracle 10g mini disk set up on z/VM 5.3 with Red Hat Linux 4.6 and above
On page 21 in the PDF Using Oracle Solutions on Linux for System Z which can be found at http://www.redbooks.ibm.com/abstracts/sg247573.html it is not clear to me if minidisks 191, 201-204, 301-302 are all needed for Oracle's use or just a few of them. What are Oracle 10g's minidisk requirements when running under z/VM 5.3 and Red Hat Linux 4.6 and above? Thanks in advance.

creating an alternate z/VM res and spool pack
We just unloaded z/VM 5.3 and would like to create an alternate RES and spool pack. Current names are 530RES and 530SPL. Does someone have simple procedures to create alternate res and alternate spool volumes so we can IPL off the alternates and leave the original res and spool untouched. The Guide for Automated Installation and Service shows how to backup the Res and saved system and segments but the SPXTAPE utility implies you want to restore to the current spool volume not an alternate. Also is anyone using symbolics in system config and/or the user directory like we do in z/OS parmlib? Thanks. David T. Juárez Department of Veterans Affairs IT Specialist
Re: creating an alternate z/VM res and spool pack
Franz your procedures worked! We are now IPLed off a different Res pack, spool and page pack. Thank you very much for your help.

I have done it several times with this procedure in user maint 1. attach new volumes to maint 2. copy all 530res, (if mod 3 530w01,530w02), 530pag and 530spl to new volumes with DDR. You can of course also restore them from a backup. 3. CPFMTXA device-of-530res 530rs1 LABEL (530rs1 is the new label of the new 530res disk), analog for all other volumes 4. Q MDISK 191 LOC This shows the location of the maint 191 on 530res. 5. DEF MDISK 111 startcyl-of-step4 size-of-step-4 530rs1 (The MAINT user must have OPTION DEVMAINT in user direct when using this command.) AC 111 T X USER DIRECT T C /530RES/530RS1/** (or whatever new label you have set in step3), analog for all other volumes save the changes DIRECTXA USER DIRECT T (The DIRECTORY statement in the new USER DIRECT must point also to the new res. Because it is not the active res it is only updated on disk, not made online) 6. Q MDISK CF1 LOC 7. DEF MDISK 111 startcyl-of-step6 size-of-step-6 530rs1 AC 111 T X SYSTEM CONFIG T C /530RES/530RS1/** (or whatever new label you have set in step3), analog for all other volumes eventually changes of the consoles, but this can also be overwritten with the standalone loader eventually changes of user_volume_include list etc. This depends if you want to start the new vm in 2nd level or lpar. In 2nd level the system sees only the volumes which you define to the user, in lpar it sees all the volumes it is allowed to by iocds. save the changes 8. ready to take IPL. You must do a FORCE start at first IPL Hope this helps. kind regards Franz Josef Pohlen Juarez, David T. schrieb: We just unloaded z/VM 5.3 and would like to create an alternate RES and spool pack.
