Steps for diagnosing a coded disabled wait state

Obtain the disabled wait state code from the from the stand-alone dump, if obtained or the Hardware Management Console (HMC). The IPCS STATUS WORKSHEET report from a stand-alone dump often contains a corresponding wait state message. For example:

Find the wait state code using z/OS MVS System Codes. If there is no recommended action:
1. Look up the wait state code in the System completion code to module table in z/OS MVS System Codes.
2. Use the module name to identify the component using the Identifying modules, components, and products table in z/OS MVS Diagnosis: Reference.
Perform a search using the wait state code, reason code, module name and component identifier to look for a known problem. If you cannot find a match, report the problem to IBM®.

Table 1. Common disabled wait states . This table contains examples where possible for illustrative purposes.
Wait state code	Reason code	Explanation	More information:
X'01B'		This is a restartable wait state that is loaded when an active SLIP trap requests an action of WAIT. The conditions specified on the SLIP command are met. The system enters a wait state, as requested. Information about the environment when the slip trap matches is presented in message IEE844W. For example: Message IEE844W: IEE844W SLIP TRAP 0001 MATCHED. ACTION=WAIT TYPE=PER. PER INFO: 207F: 010FEED2 PSW: 440cc000 810FEED6 CR 3-4 80000001 00010001 GR 0-3 00000000 01DA9600 00000041 01F993B8 4-7: 01EA9600 00000000 010FEE80 00F8C000 8-B: 00FD6F80 010FDA8 00FCD680 9598947F C-F: 01F998E0 014E7040 01EA9140 0000000C AR 0-3: 00000000 00000000 00000000 00000000 4-7: 00000000 00000000 00000000 00000000 8-B: 00000000 00000000 00000000 00000000 C-F: 00000000 00000000 00000000 00000000 RESTART THE SYSTEM TO CONTINUE	The topic on SLIP problem data in the SLIP work area in z/OS MVS Diagnosis: Tools and Service Aids.
X'040'		The system ended a task during nucleus initialization program (NIP) processing.	Diagnosing an abend
X'064'	X'005'	Indicates that an ABEND was issued during NIP. To diagnose using a SADUMP, do a SYSTRACE ALL, max PF8 to the bottom of the output and do a 'F *SVC PREV' to locate the ABEND issued.
EXAMPLE: WAITX'064' RSNX'005' `00 0001 00000000 *SVCE D 040C1000 814E1EE2 00000010 84000000 84878000 10000201 00000000 0001 0001 BEC5A7BA2DAC255B 00800004 00400000`
X'064'	X'009'	A program check occurred during nucleus initialization program (NIP). Message IEA304W explains the wait state and entry code. If the message does not appear on the console, you can find the message in the wait state message area (WSMA). The WSMA is described in z/OS® MVS™ Data Areas in the z/OS Internet library. To diagnose using a stand-alone dump, format the LCCA by entering the CBFormat LCCA`x` command (where `x` is the CPU ID).	Diagnosing an abend
X'0A2'	X'004'	The operator entered the VARY XCF,sysname,OFFLINE command to remove the system from the sysplex.	Ask the operator or system programmer why the system was varied out of the sysplex before continuing with diagnosis.
	X'104'	I/O is prevented because a system is fenced.	Go to Diagnosing a system partitioned from a sysplex because of status update missing
	X'10C'	Cross-system coupling facility (XCF) or cross-system extended services (XES) encountered an unrecoverable error and stopped the system. The system also issues this wait state in response to an operator request to stop the system. For information about diagnosing sysplex problems see, z/OS MVS Diagnosis: Reference.
