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 . If there is no recommended action:
1. Look up the wait state code in the wait state code to module table in .
2. Use the module name to identify the component using the module identification table in .
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.

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.

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 the ABEND issued.

	X'009'	A program check occurred during NIP. Accompanying message IEA304W further explains this wait state and entry code. If the message does not display on the console, you can find the message in the wait state message area (WSMA). The WSMA is described in . To diagnose using a stand-alone dump, format the LCCA by entering the CBFormat LCCAx 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 has been prevented as a result of a system being 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 encountered a non-recoverable error and stopped the system. The system also issues this wait state in response to an operator request to stop the system. See for information about diagnosing sysplex problems.	Diagnosing an enabled or disabled wait state
