Defining an LPAR on a z box to run LINUX
We are researching the possibility of putting up a LINUX LPAR on our z/890 for a Proof of Concept. We currently have 3 general purpose CP's turned on in the box. All 3 of the general purpose CP's are available for use to the 3 z/OS LPAR's we run on the machine, none of the CP's are dedicated. I know on the HMC's Activation Profile you can select the LPAR mode ESA/390 or LINUX (and a few other options as well). What I'd like to do is Build a 4th LPAR to be a LINUX LPAR, assign that LPAR just a single processor, it's own Devices via IOCP along with a chunk of memory. This LPAR would just be for me to play around with and learn on. Now my question is the following. Since all three of my General Purpose CP's are shared across LPAR's that are EAS/390 Mode LPARS, can I use one of those same three General Purpose CP's for this LINUX Mode LPAR? Or must all LPAR's assigned to a CP be defined as the same mode type? i.e. EAS/390 or LINUX. -Thanks Dave. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

Now my question is the following. Since all three of my General Purpose CP's are shared across LPAR's that are EAS/390 Mode LPARS, can I use one of those same three General Purpose CP's for this LINUX Mode LPAR? Or must all LPAR's assigned to a CP be defined as the same mode type? i.e. EAS/390 or LINUX. In your case, stick with standard engines (ESA/390) and define the LPAR just like your z/OS LPARs with shared processors. Also, define ONLY the devices that Linux will be allowed to use. If you share all devices, your Linux will a) take forever to IPL, and b) have unfettered access to all your data. Linux pays no attention to any z/OS security system or dataset protections. Your gun, your head. To save you enormous grief, ask IBM for a trial copy of z/VM. Linux in LPARs is a royal PITA, and you'll get much better ROI from running Linux in VM guests. It's also a lot safer if you're sharing hardware with another OS, eg z/OS. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

Re: Upgrading from SLES10 GA to SP1 in 9 Easy Steps
Mark, thanks for clarifying the procedure for SLES10 SP1 update without using a network installation server. I followed your steps and they work just fine. The only thing I would add is a step between 6 and 7 to make sure that zmd is running and is done starting otherwise this seems to cause some problems. I use top to see if it is done or issue 'rug sl' and look for anything that is 'pending'. I have two problems that I wonder if others have seen or not: 1-After all packages are updated to SP1, if I issue SPident, get a System is NOT up-to-date. It seems like it finds SLES10 + updates and expects SLES10 SP1 even though I am at the SP1 kernel level and the system login prompt says I am at SP1 and so does /etc/SuSE-release.

Re: Defining an LPAR on a z box to run LINUX
Dave, if you have spare PU on your z890, I would strongly recommend to get IFL for test purposes which can be free for 3 or 6 months. It is also possible to get trial contract for z/VM, which is a good idea. Are your CPs on full speed or not ? If you assign one capped CP which you share with production, it will be wy slower than IFL which is full speed. And slow response is not a good start for PoC. We have many customers running Linux on z890 happily, most of my customers run it on IFL with or without z/VM. Marian Gasparovic IBM Slovakia --- Rakoczy, Dave [EMAIL PROTECTED] wrote: Yes...

It seems like it finds SLES10 + updates and expects SLES10 SP1 even though I am at the SP1 kernel level and the system login prompt says I am at SP1 and so does /etc/SuSE-release. Anyone else sees this problem or is it just me! It is not just you! We get the same result. In our case it's a direct result of having installed Velocity's snmpd RPM for SLES10. I'm a little unhappy about the way this particular situation played out, as we apparently need Velocity's version of net-snmp for the updated MIBs, but SuSE have made it ever so slightly difficult to remove their version of it from SLES10 as it is required by hplip (the HP LaserJet drivers). In the end I just did a force install of Velocity's RPM over SuSE's. Perhaps there may have been a less rude method. The other package which causes us to not show a supported service pack in SPident is yast2-bootfloppy. This package exists in GA and is installed by default, and SPident expects to see an updated revision... but the actual package does not appear on my SP1 media. I don't know why. I think I'm going to solve the problem, now that I've identified it, by adding it to my list of packages to remove completely. I'm not sure what to do about the Velocity net-snmp issue. It would be nice, since I know nothing whatsoever about the issues, to have received an add-on (or adjunct) package from Velocity, containing new MIBs to simply add to SuSE's net-snmp package. SPident -vvv should show you which packages are preventing it from achieving nirvana in your particular environment. ok r. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

Re: Upgrading from SLES10 GA to SP1 in 9 Easy Steps
Ok, I have resolved my problem. I don't have any 3rd party software installed like you do Raymond but when I did a SPiden -vv it gave me a list of the packages it didn't like. Sure enough, when I look at the SP1 installation CDs, the level for these packages is a bit newer than what I have. Why the SP1 upgrade did not resolve these and why they don't show up when I do an Online Update in Yast is beyond me. I used Yast and did 'Software Management' to install the later version of the pacakges and now SPident reports correct results. Thanks for those how helped. Aria.

Anyone else sees this problem or is it just me! It is not just you! We get the same result. In our case it's a direct result of having installed Velocity's snmpd RPM for SLES10. I'm a little unhappy about the way this particular situation played out, as we apparently need Velocity's version of net-snmp for the updated MIBs, but SuSE have made it ever so slightly difficult to remove their version of it from SLES10 as it is required by hplip (the HP LaserJet drivers). In the end I just did a force install of Velocity's RPM over SuSE's. Perhaps there may have been a less rude method. The other package which causes us to not show a supported service pack in SPident is yast2-bootfloppy. This package exists in GA and is installed by default, and SPident expects to see an updated revision... but the actual package does not appear on my SP1 media. I don't know why. I think I'm going to solve the problem, now that I've identified it, by adding it to my list of packages to remove completely. I'm not sure what to do about the Velocity net-snmp issue. It would be nice, since I know nothing whatsoever about the issues, to have received an add-on (or adjunct) package from Velocity, containing new MIBs to simply add to SuSE's net-snmp package.
