A
reconfiguration display request (a DISPLAY M=CORE command or an internal
request) asked the system to display the status of selected cores.
When you issue the DISPLAY M=CORE command from a PR/SM partition,
the system displays the status for the logical cores. The system
information presented on the CPC SI line reflects any dynamic upgrades
that have been performed. The information presented on the CPC ND
and CPC ID lines remain unchanged across any such upgrades.
In
the message text:
- h
- Indicates whether the system is enabled for HIPERDISPATCH (Y)
or not (N).
- mm
- The maximum MT mode that can be supported by both the hardware
and this IPL of z/OS®.
- cn
- The MT mode for standard CP cores. This can be modified by using
the MT_CP_MODE parameter in the IEAOPTxx member. For more information,
see IEAOPTxx MT_CP_MODE in z/OS MVS Initialization and Tuning Reference.
- zin
- The MT mode for System z Integrated Information Processors. This
can be modified by using the MT_ZIIP_MODE parameter in the IEAOPTxx
member. For more information, see IEAOPTxx MT_ZIIP_MODE in z/OS MVS Initialization and Tuning Reference.
- cId
- The core identifier.
- wst
- The state of the core, with each letter representing a different
state:
- w
- When the core is being managed by WLM, this will be “W”,
otherwise it will be blank.
- s
- The status of the core, which can be one of the following:
- + indicates the core is online.
- - indicates the core is offline.
- / indicates the core is in a mixed state, because
the core is online but the threads currently online are unexpected
with the MT mode for this core type. This state can occur in certain
system abnormal conditions. You can generally get out of this state
by reconfiguring the core to its desired state. For more information,
see IEAOPTxx MT_xxxx_MODE in z/OS MVS Initialization and Tuning Reference.
- N indicates the core is neither online nor able to be configured
online.
- t
- The type of the core, which can be one of the following:
- (a blank) – the core is a standard CP.
- A – The core is a System z Application Assist Processor.
- I – The core is a System z Integrated Information Processor.
- tIdL
- The lowest CPU address of a thread that belongs to this core.
- tIdH
- The highest CPU address of a thread that belongs to this core.
- v
- The HIPERDISPATCH vertical-ness of the core:
- H – The core is classified as a vertical high core.
- M – The core is classified as a vertical medium core.
- L – The core is classified as a vertical low core.
- p
- Indicates whether the core is parked (P) or unparked (blank).
- xxxx
- The interrupt subclass mask for the core.
- t
- The state of each thread that belongs to this core. There are n visible
thread states, where n = (tIdH-tIdL)+1
and is OS and model dependent. The CPU ID for the first thread is tIdL.
The state can be one of the following:
- + indicates the thread is online due to the
current MT mode for this core type.
- - indicates the thread is offline due to the
current MT mode for this core type.
- N indicates the thread is offline and expected to be offline due
to the current MT mode for this core type. For more information, see
IEAOPTxx MT_xxxx_MODE in z/OS MVS Initialization and Tuning Reference.
- CPC ND = tttttt.nnn.mmm.pp.ssssssssss
- The central processing complex node descriptor, in EBCDIC, where:
- tttttt
- The type number.
- nnn
- The model number of the processor at the last IML/POR. Note that
if the processor is concurrently upgraded to a new model, this number
will not reflect the new model until the next processor IML/POR.
- mmm
- The manufacturer.
- pp
- The plant of manufacture.
- ssssssssssss
- The sequence number.
- dd
- The approximate percentage, in decimal, of the actual effectiveness
compared to the normal effectiveness of the CPC.
- Indicates that a reduction in the current capability of the central
processing complex (CPC) has been detected.
- CPC SI = text02
- Where text02 is:
tttt.nnnnnnnnnnnnnnnn.mmmmmmmmmmmmmmmm.pppp.ssssssssssssssss
Model: oooooooooooooooo
This
is the system information from the STSI instruction, in EBCDIC, where:- tttt
- The type number.
- nnnnnnnnnnnnnnnn
- The model-capacity identifier. Note that the model-capacity identifier
is updated after a concurrent upgrade.
- mmmmmmmmmmmmmmmm
- The manufacturer.
- pppp
- The plant of manufacture.
- ssssssssssssssss
- The sequence code.
- oooooooooooooooo
- The model number.
Note: If the core is concurrently upgraded to a new
model, the model number in field oooooooooooooooo will
reflect the new model without a core IML/POR.
Note: The "Model:"
line is displayed only if the model number oooooooooooooooo differs
from the model number/model-capacity identifier nnnnnnnnnnnnnnnn.
- CPC ID = ii
- The central processing complex node identifier, in binary.
- CPC NAME = cpc_name
- The central processing complex name, in EBCDIC.
- LP NAME = lp_na
- The logical partition name, in EBCDIC.
- LP ID = jj
- The logical partition identifier, in binary.
- CSS ID = cc
- The logical channel subsystem identifier, in binary.
- MIF ID = m
- The multiple image facility identifier, in binary. The MIF ID
appears only if you are running in LPAR mode.
