More from Mike MacIsaac, an IBM z/Vm and Linux on System z consultant working with the z/VM and Linux Lab-based services team in IBM Poughkeepsie, NY and currently working on an ITSO residency to update the Virtualization Cookbooks. This updated book will be called The Virtualization Cookbook for z/VM, RHEL and SLES, SG24-8147
Thought I'd blog a bit more on "The Virtualization Cookbook" residency. The first week we got a z/VM ESP system installed in a 2-node SSI cluster (see my blog post on that here). We defined an IDENTITY (aka an MCVM) named LNXADMIN with the system on one member being focused on RHEL and the other on SLES (addressing the distributions alphabetically). We got Linux systems installed and customized on the two IDENTITYs and also "golden images" installed on USERs (aka SCVMs). We're addressing the "clone vs. build" question with the answer "the customer is always right". That is, you can clone with scripts that may be Linux or z/VM-based or you can build (e.g. Kickstart and AutoYAST). We will address the existing open-source appliances (Web server, Samba server, LDAP server, Application Development server) and may add others.
Monday we got DirMaint, SMAPI and RACF enabled and customized. RACF was, let's say "challenging", but the steps in the existing book, (on http://www.vm.ibm.com/devpages/mikemac/CKB-VM62.PDF ) worked. Yes, near the end, for both members, you have to IPL from the RES volumes, but set the common volume 1 on the SAPL screen and still use extent 1.
Today starts work day 8 of 20 and we still have many items "on our plate" that we'll try to address (I had mentioned some of these earlier):
-) Multipathing of FCP/SCSI disks
-) z/VM HYPERPAV
-) AutoYast on SLES
-) Beef up Monitoring chapter including MONWRITE data
-) Address VIR2REAL EXEC
-) Kiwi on SLES
-) Beef up "z/VM Live Guest Relocation" chapter
-) Add section on z/VM "LOGON BY" for audit trails
-) Beef up RACF section
-) Add a section on the "Linux Terminal Server"
-) Add a CRON Service Virtual Machine for z/VM
-) Define command-specific z/VM privilege class
