Hi, All, We recently installed RHEL 6.5 on z/VM 6.2 using the latest edition of Michael MacIsaac's "Virtualization Cookbook", which is written around z/VM 6.3 and RHEL 6.4.
We "cloned" a new Linux guest from our RHEL 6.5 "golden image", and one of our Linux admins noticed some "strange" messages in the clone's boot log: ===== Begin paste ===== part of the golden image configuration included a section on settings at boot time - see section 9.2.6 of the pdf. in looking at the boot log for ch2lqvpsx I see the following messages HCPDTV040E Device 0190 does not exist Error: non-zero CP response for command 'DET 190': #40 HCPDTV040E Device 0191 does not exist Error: non-zero CP response for command 'DET 191': #40 HCPDTV040E Device 019D does not exist Error: non-zero CP response for command 'DET 19D': #40 HCPDTV040E Device 019E does not exist Error: non-zero CP response for command 'DET 19E': #40 ===== End paste ===== The concern is over the HCPDTV040E messages for the MDISKs used at CMS logon time. The cited section of the "Cookbook" states: ===== Begin paste ===== In order for z/VM 6.3 to relocate guests between single system image (SSI) members, there must not be any links to CMS disks. The LNXDFLT PROFILE creates links to minidisks and assigns virtual device numbers 190, 191, 19D, and 19E. These addresses must be detached. The vmcp module is used to accomplish this. To do these two tasks, edit the /etc/rc.d/rc.local file, which is run at boot time: # cd /etc/rc.d # vi rc.local And add the following lines: #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local chshut halt vmcmd logoff chshut poff vmcmd logoff modprobe vmcp vmcp det 190 vmcp det 191 vmcp det 19d vmcp det 19e The z/VM virtual machine should now be logged off when you halt or power off Linux. ===== End paste ===== The appearance of the HCPDVT040E messages seems to suggest that the CMS disks are already detached when the rc.local script issues the vmcp det xxx commands. If true, can anybody say when (and by whom or what process) those disks are detached, apparently before rc.local runs? Is that "new" for RHEL 6.5?
