Thanks Kris for a quick answer, and also thanks to another for an off-line
reply. I do appreciate it.
However, I'm still not sure I have a solution. Let me describe the
problem a bit better. I'm trying to ascertain the location of resources
in the System z hierarchy - that is CECs have LPARs, and LPARs have
systems which may be Linux or z/VM, and z/VM systems have systems, which
may also be Linux or z/VM (I know there are a lot of other possibilities,
but these are the most interesting). I'd like to do as much of this as
possible on Linux rather than from z/VM, thus the request for CP commands,
not CMS (so I'm even more hesitant to use CPHOST which is a z/VM add-on).
I can get a lot of information from /proc/sysinfo. For example, on a third
level Linux, the following data are interesting:
# grep "LPAR Name:" /proc/sysinfo | awk '{print $3}'
LVM1
# grep "VM01 Name:" /proc/sysinfo | awk '{print $3}'
VM140
# grep "VM00 Name:" /proc/sysinfo | awk '{print $3}'
ZVMMAPLX
I know the system is running on the LPAR named "LVM1". Because there is a
VM01 entry, I can assume this is a second level z/VM running on the user
ID named "VM140". Also I know the third level Linux is running on the user
ID "ZVMMAPLX". I can also determine the CEC's machine type, model number
and serial number with other data in /proc/sysinfo.
So that tells almost the entire hierarchy *except* for the system
identifier of the first level z/VM system:
CECs
|
+-mach-type-X-model-num-Y-serial-num-Z
|
+-LPARs
|
+-LVM1
|
+first-level-zVMs
|
+-?????????
|
+-second-level-z/VMs
|
+-VM140
|
+-third-level-Linuxes
|
+-ZVMMAPLX
Neither /proc/sysinfo, DIAG 0, nor the STSIUSE EXEC seem to supply that.
Any other ideas other than CPHOST? (I could require this value as a
parameter, but it would be more convenient and reliable if it could be
ascertained.) Thanks in advance.

P.S. Typing out the hierarchy has shown to me that I may be mixing user
IDs with system identifiers - perhaps I *do* have the entire hierarchy in
that I know there is one z/VM running on the LPAR LVM1. However, we
usually remember z/VM systems by system identifier, not by LPAR name.
