VM user and Virtual machine / guest os are indeed one and the same LOGOFF, that's like pulling the plug out, not an orderly shutdown. So better stop your Linuxes with the appropriate Linux command and then enter LOGOFF.
At the other hand: modern Linuxes register themselves to receive shutdown signals from CP, what means that if the LPAR gets stopped, of when you issue CP SHUTDOWN, or when one uses FORCE, these Linuxes will shutdown themselves and CP gives them some to do that. This time can be defined in SYSTEM CONFIG (on MAINT CF1) or by a CP SET command; by default, the time is 0 and FORCE or SHUTDOWN won't give Linuxes any time to stop. To find out the details, use QUERY SIGNALS or QUERY SIGNAL SHUTDOWN (or something like it, my memory isn't that good anymore to remember all details of relatively new commands). HELP CPQUERY MENU is a start to find the details online. -- Kris Buelens, IBM Belgium, VM customer support 2007/10/20, GnanaShekar Subramani <[EMAIL PROTECTED]>: > > Hi, > > Thanks a lot for your help. > I am now able to enter the CP commands. > > After logging in as a VM user if I log off (LOGOFF command), I guess the > virtual machine / guest os is getting shutdown. > > I guess the VM user and Virtual machine / guest os are one and the same. > > I was also able to bring up the virtual machine / guest os using the IPL > commands.
