Re: vswitch eth0 stops working after kernel upgrade
Our vm level is 4.4 but why is the VM level relevent. Is it common that certain linux functionality does not work under elder vm versions? Is there any known issues with vm4.4 vswitch and these kernels?

From the z/VM CP Programming Services book, return code 8 means message id found but message class or path ID invalid. What it indicates to me is some sort of error in netiucv, the iucv interrupt handler, or in memory management. When netiucv performs iucv_receive() it passes in the message id, path, and class that were pulled from the interrupt buffer when the message came in. With that design, it is supposed to be impossible to get RC=8. You should report this error to your Linux service provider. There have been a couple of patches to IUCV support since April 2004 stream was released. Is there other IUCV activity going on (e.g. vmlogrdr)? How many virtual CPUs? Of course, from a network perspective, it's time to dump IUCV and move to z/VM Guest LANs or the Virtual Switch.

Re: initctl issues while initrd hacking - SLES9 - S390X
Let me refine my question ... What controls the mounts that exist after you pivot_root it isn't done through the fstab - because it's not synced in my case. So what can it be? googlin' on Lior.

Re: How to place a file on the linux instance without networking.
Hi Dave, fir of all thanks for your swift reply.. The problem is that I can't transfer any files to my linux instance (no networking) so I can't compile the cmsfs util on my linux (although it looks like good practice putting it there proactively). I couldn't find any info on e2 is it commercial/opensource where''s the util page etc.. Ronald (thanks as well) suggested that I use cp link to add a shared disk to the broken machine mount it and copy the file the problem is - when I issue a a cp link command is that it gives me a ' no read password' error and does not let me link it. I understand that these is a method of disc based access control but where is it defined? regards Lior. On Mon, 27 Dec 2004 09:26:31 -0600, Dave Jones [EMAIL PROTECTED] wrote: Hi, Lior. I can think of a couple of ways you can get files transfered to a VM Linux guest that does not have networking connectivity enabled: 1) move the Linux files you want transferred to a CMS disk that the Linux image can access. Then you can use Rick Troth's way cool cmsfs Linux utility to read the files on the CMS disk and transfer then (either in binary or EBCDIC-ASCII mode) to the Linux file system. With this approach, you're basically pulling the needed files from CMS onto Linux; the Linux guest must be up and running. 2) there is a nifty new utility called E2 that provides a r/w interface to the Linux ext2fs file system from Rexx execs running under CMS. It was developed to address exactly this kind of problem with running Linux under VM. With the Linux guest quiesced, or better yet, logged off, a CMS user can link to the Linux minidisk in r/w mode and then use the E2 utility to read and write files directly into the Linux file system. Linux files can be moved, deleted, renamed, etc., as well. HTH. DJ Lior Kesos wrote: As my questions imply I'm a linux geek wallowing in the new for me mainframe space...

Where did cpint_load go? (in SLES9)
I have a set of scripts that I need to maintain that use cpint_load to load modules through a custom initrd. I'm porting these scripts to SLES9 and I suddently found out that cpint_load isn't distributed in the cpint package anymore? I'm not familiar with the design idea of why this was used in the first place - and the initial developer is long gone ... Was cpint_load just a temporary hack? Is there a subsitute in SLES9? Should I just write a workaround or is there something importent in the loading of cpint that cpint_load was in charge of doing? thanks in advance for any help offered regards Lior -- Peace Love and Penguins - Lior Kesos -- 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: Where did cpint_load go? (in SLES9)
Thanks (Ronald and Mark) for the swift answer... Because I'm working off a modified initrd I guess I'll manually do all the sanity check and the /dev magic or actually implement most of the script to the file-system and do a simple insmod cpint in the end... regards- Lior.

Checks /proc/devices to see what major device number it got assigned by the kernel 3. Creates the corresponding entries for that in /dev 4. Sets up a couple of symbolic links in /dev 5. Sets some owner and group names on the devices SUSE appears to have decided to hard-code the device number to 107 (which is normally used by the 3DFX graphics card, so not used on the mainframe), and has most likely put the needed device entries in /dev already. As a result, they don't include cpint_load and cpint_unload as part of their packages. As a first attempt at experimentation, you could try replacing the calls to cpint_load with insmod cpint and see what happens.
