ISG022E

Explanation
An error caused this system to disrupt the global
resource serialization ring. All active global resource serialization
systems, including this system, become inactive global resource serialization
systems.
In the message text: sysname
The name system that disrupted the global resource serialization
ring.
COMMUNICATION FAILURE
A channel-to-channel (CTC) device failed. Preceding message ISG046E
identifies the CTC.
SOFTWARE FAILURE
There is a logic problem in this system's global resource serialization
processing. Preceding message ISG021I or ISG046E identifies the error.

System action
Message ISG022E or ISG023E appears on each of
the systems that became inactive global resource serialization systems
as a result of this error.  An inactive global resource serialization
system suspends any task that attempts to obtain or release global
resources.
The system writes an SVC dump and a logrec data set
error record.

Operator response
Consult the system programmer and the operators
on the other global resource serialization systems before taking
any recovery action. See the operator response to message ISG023E.
If COMMUNICATION
FAILURE appears in the message text, find the device associated
with the problem by doing one of the following: Look for preceding message ISG046E to identify the failing CTC.
Enter the DISPLAY U command for the device associated with the
problem. If you have not identified the failing device, enter the
DISPLAY U command for a number of devices. Pick the starting device
number for the command from the device numbers in the configuration
path chart.

System programmer response
Help the operators on global resource
serialization systems decide how to rebuild the global resource serialization
ring.  See the explanation for message ISG023E.
If this system
does not become an active global resource serialization system when
the global resource serialization ring is rebuilt, ask the operator
on one of the active global resource serialization systems to purge
this system by entering the VARY GRS(sysname),PURGE
command, where sysname is the name of this system.
Then correct the error and reIPL this system.
If the program
is not in error, and the error recurs, search problem reporting databases
for a fix for the problem. If no fix exists, contact the IBM® Support Center.
