Re: How to share files/disk between 2 LPARS
Lee, Maybe a stupid question, but have you compared the minidisk definitions on both Linuxes and checked if all the different layers say R/W ? From each Linux: # vmcp q v address # vmcp q md address location # cat cat /sys/devices/css*/*/0.0.address/readonly Also, I hope your planning to use a shared directory and at least xlink protection between your z/VM systems for the shared volumes.

The way it always happens to me is having two systems running that can both see each other's disks. It seems the volumes other than the IPL volume are referenced by labels (volsers), not real device numbers (rdevs). So I believe the system with the higher rdevs starts spooling and paging to another system's volumes. There are a few ways to avoid this: 1) Use Offline_at_IPL in SYSTEM CONFIG to prevent each system from seeing the other systems' disks. 2) Relabel the W01, W02 (No W01 and W02 volumes if using 3390-9s), SPL and PAG volumes at install time, at the start of the INSTDVD EXEC, for example. 3) Relabel all 5 volumes (3 for 3390-9s) immediately after install. #1 and #2 have the side effect of having mutiple volumes with the default label of the res pack (540RES for example). If a z/OS system can also see these volumes, the sysadmins get upset because it slows down a z/OS IPL. If that isn't a problem, #2 is probably the easiest. #3 can be tricky, so it is documented in the Virtualization Cookbooks (http://www.redbooks.ibm.com/abstracts/sg247493.html for SLES or http://www.redbooks.ibm.com/abstracts/sg247492.html for RHEL), section 4.11 Hope this helps.

Re: Multipathing for ECKD devices

Re: 2nd level zVM
You need to restore the share segment from the old system to the new. The spxtape command will backup and restore DCSS and save system. Question, on your IPL volume, do you have spool space allocated. In the old days I use to have two vm sysyem to manage. This was one of things I need to do when make the 2nd system the same as the 1st. - Original Message - From: Chan Kok Leong [c...@chankle.net] Sent: 10/09/2009 04:17 PM ZE8 To: LINUX-390@VM.MARIST.EDU Subject: Re: 2nd level zVM Yes, I had tried following the procedure described in the pdf but it does seems incomplete (deliberate?).

0605 as an octal number is 389. So 389/100 = 3 when truncated.

Re: Math Error
Some examples from other OS implementations, which show (even within a
vendor) differing results. Is AIX right or is SLES 10 right? I'm not
sure.
SuSE (or probably the level of Korn Shell) changed (I think) between
SLES 9 and SLES 10. AIX and Solaris seem to be acting as a human
expects.

WIth good reason: they're astonishingly insecure. If they're on the same physical machine as your MVS machine then you may not care, since there's no physical wire to be sniffed between them. As far as I know they do still exist in modern distros and you should be able to install them.

For this to work, you must have OpenSSH on the mainframe side. And establish
SSH keys between Unix System Services and the Linux machine. If you Google ssh
keys you'll find lots of sites on how to do that.
