z/VM: CP Commands and Utilities Reference - z/VM - IBM

The data displayed by this command represents the system at a single,
self-consistent instant. (The system is locked briefly so that no changes occur while
the data is being gathered.)
Response 1:
userid ttnn aa bbb ssssssss/tttttttt userid2...
(as many as 2 users per line)
userid1
userid2
each identifies a virtual machine.
tt is a code for the VMDTYPE, if other than the user. It can be:
v MP for virtual MP. Each virtual CPU defined for a user shows up separately
with the same user ID and a type of MP. Each is a separately dispatchable
unit.
v Blank if the VMDBK is any other type.
nn is the virtual CPU number of this VMDBK for virtual MP guests, or is blank if not
for virtual MP guests.
aa is the current list status of the user:
Status List the User Is On
Q0 The dispatch list and exempt from eligible list delays
Q1 The dispatch list and entered as an E1 user
Q2 The dispatch list and entered as an E2 user
Q3 The dispatch list and entered as an E3 user
E1 The E1 eligible list
E2 The E2 eligible list
E3 The E3 eligible list
L0 The limit list and exempt from eligible list delays.
L1 The limit list and the user entered the dispatch list as an E1 user.
L2 The limit list and the user entered the dispatch list as an E2 user.
L3 The limit list and the user entered the dispatch list as an E3 user.
Note: Users who have been defined as QUICKDSP are in Q0 status whenever
they are in the dispatch list. Other users may show up briefly as Q0 if
they really belong in the eligible list, but must make brief appearances in
the dispatch list (for example, to finish with and release a lock).These
users could also appear in the L0 status.
bbb
is one of the following status indicators:
Rnn
indicates that the user is the current RUNUSER on the specified real
processor, where nn is the processor ID (in hexadecimal).
PG
INDICATE QUEUES
indicates that the user is in page wait; the user’s virtual machine is not
executing because CP is trying to bring in a page from a paging device.
IO indicates that the user is in I/O wait. The user’s virtual machine is not
runable and has I/O either queued by CP or already in progress.
Note: When a user performs I/O through a synchronous DIAGNOSE
instruction (as when running CMS), userid shows up as I/O, not as
EX, while the instruction waits for the I/O.
