Hi
Thank you for reading my email.
I have some question about PR/SM and I would be very thankful for any
answer.
- System z PR/SM is implemented as hardware and it is capability of
IBM mainframe hardware.
-------------------------<unsnip>--------------------------------
So far, so good.
-----------------------<snip>-------------------------
- z/OS or z/VM are interfaces (command line or GUI ) that let us use
the above capability to define LPARs. but each of them can utilize
this capability to some extent.
-------------------------<unsnip>---------------------
NO. z/OS and z/VM are operating systems, each having the capability of
"reaching into" microcode to define/examine the I/O configuration by way
of a utility program. z/OS and z/VM are USERS of the LPAR, primarily
providing system, scheduling and other services to application programs.
Rather like Windoze on the PC.
---------------------------<snip>----------------------------
- PR/SM can let z/OS to install and run Linux (Linux for System Z) on
its LPAR,
---------------------------<unsnip>------------------------
The presence or absence of z/OS on any LPAR has no bearing on the
presence or absence of Linux for System Z on any other LPAR. Neither is
required to run the other and only one will run at any one time in any
one LPAR. If you have 4 LPARs defined and activated, you might easily
run z/OS in LPAR # 1, z/VM in LPAR # 2, z/VSE in LPAR # 3 and Linux for
System Z in LPAR # 4. And none of these LPARs need know anything about
the other three. As far as the operating system is concerned, each LPAR
might as well be a completely separate machine. Balancing the resource
utilization of the CEC between the various LPARs is strictly a PR/SM
function.
------------------------------<snip>-------------------------
Are the above assumptions correct?
------------------------------<unsnip>-------------------------
I hope I've given you a clearer understanding. If not, contact me
privately and I'll give you my phone number. I'm in Metropolitan
Chicago, Illinois, USA. Please don't take offense, but I have the
feeling that English isn't your first language,
