The same way it is done on Red Hat for Intel. The LVM FAQ list is available by googling "LVM FAQ RHEL". > 1. LVM on windows is using Drives & partitions to create LVM , so when it > comes to Z/OS .. LVM is a generic acronym. The Linux implementation is completely different than the Windows implementation. Also, please don't confuse the System z processor with z/OS. Linux and z/OS are separate operating systems that run on the System z hardware. There is no interdependency between the two other than they can share the same hardware. And yes, there are a lot of IBM people who don't understand the difference either. > what is used generally by various users > > Z/VM minidisk as Linux Drives , which is then used to create LVM and fstab > entries in Linux are Z/VM minidisk That is the only version that Linux can support directly. > or we use MVS - ZFS datasets , formatted and used as Drives on Linux To do this, Linux must access them via a network file system, such as NFS.

They're separate systems, and you must treat them that way. There are ways to allow Linux to get identity and authorization information from z/OS (ie, LDAP), but Linux must get that information via a method it understands (usually over the network). If you want security in Linux, you must use Linux-based methods. > is there any Z/VM , Z/LINUX , Z/OS - Z/Linux tutorial information Getting Started with Linux on System z (available for download from www.vm.ibm.com) is pretty good. Also a new IBM redbook is in process on installing and getting started is in the works (there are older copies available from www.redbooks.ibm.com). Beyond that, the most important message is "once the Linux system is started up, *there is no difference in operations and management from Intel Linux*." It's Linux. There are minor differences in device names, but that's it. If you need to do it on Linux, you do it the same way you do it on Linux anywhere else. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
