When a wait state occurs, the Program Status Word (PSW) is displayed at
the operator's console in the following format: xxyyyyyyzzzzzwww xxyyyyyy is the left half of the program status word. This half may be

The system is waiting for OOyyyyyy System wait caused by an error condition.
zzzzzwww is the right half of the program status word. The wait state
code is found in the right half of the PSi when the CPU is in
the wait state. The wait state code, www, indicates the error
condition. Wait 001 002 The machine check handler Probable hardware error.

found an unrecoverable failure. 003 A system failure occurred before a valid warm start was performed. 004 This wait state code is loaded by D8KD8P when a console, or an
output device is not operational, or when a console or output
device produces an inexplicable error status. Probable hardware
error. 005 D8KCPI could not find an operational primary or alternate console. Probable hardware error. 006 This is a normal wait when a system shutdown is completed. 007 A program check, a machine check, or a permanent I/O error was
found by the checkpoint program. 008 Checkpoint and system shutdown are complete. If the system is
running under an alternate console, error messages DftKCKP910I, DMKCKP911W, DMKCKP960I, and D8KCKP961I are not displayed. 009 An error condition occurred that prevents a warm start.
If the system is running under an alternate console, error
messages DMKCKP910I and DMKCKP911i are not displayed. OOA A machine check occurred while DftKSAV was attempting to save or
restore a page image copy of the nucleus on a SYSRES device. Probable hardware error. OOB A machine check occurred before initialization was complete. OOC An attempt was made to IPL from a disk that did not contain a
system. Thus, the wait state code OOC entered on disk by the
Format/Allocate program is encountered. OOD The machine size defined during system generation is greater than
the real machine size, or a hardware error has occurred which
inhibits V8/310 from using the required storage. 1-404 IBM V8/310 System Logic and Problem Determination--Volu.e 1

OOF Hardware errors are being received on paging device(s).
The wait state that causes this code is preceded by message DMKPAG415E CONTINUOUS PAGING ERRORS DASDxxx 010 The SYSRES device, on which DMKSAV is attempting to write a page
image copy of the nucleus, is not mounted or not ready. 011 An unrecoverable error, other than a machine check, occurred while DMKSAV attempted to write a page image cOFY of the nucleus on the SYSRES device. 012 The normal wait state code loaded by when it has completed
