Failure of the SMSPDSE or SMSPDSE1 address space

Symptoms

The deactivation of the SMSPDSE is indicated by an IGW007E message.

IGW007E SMS HAS BEEN DEACTIVATED DUE TO A FATAL ERROR RETURN CODE (IN 
HEX): return-code REASON CODE (IN HEX): reason-code {A DUMP HAS BEEN 
TAKEN|NO DUMP HAS BEEN TAKEN}

The deactivation of the SMSPDSE1 address space is indicated by an IGW077E message.

IGW077E SMSPDSE1 DEACTIVATED DUE TO A FATAL ERROR RETURN CODE: 
return-code REASON CODE: reason-code A RESTART OF SMSPDSE1 IS 
RECOMMENDED. TO RESTART ENTER: VARY SMS,PDSE1,RESTART

External symptoms include, but are not limited to, delays in job initialization and job termination, delays in job processing, and S30D abends.

How to investigate

The deactivation of the SMSPDSE is indicated by an IGW007E message.
The deactivation of the SMSPDSE1 is indicated by an IGW077E message.

These messages are issued as a highlighted operator action message that requires immediate attention. Both messages will remain on the console until recovery action is taken.

In the case of the deactivation of the SMSPDSE1 address space PDSE processing will be held or corralled until such point that the SMSPDSE1 address space is restarted. This corralling of PDSE activity will have an adverse affect on LPAR where the error occurred.

Recovery actions

Proceed to step 2 if the SMSPDSE address space was deactivated. Continue with this step if the SMSPDSE1 address space was deactivated. Attempt to restart the SMSPDSE1 address space by issuing the following command
```
VARY SMS,PDSE1,RESTART 
```
A restart of the SMSPDSE1 address space is almost always successful. Proceed to the next step in the event that the address space fails to restart.
Obtain a stand alone dump.
IPL the LPAR.
Open an incident with the service center and gather and transfer in for review the SADUMP and previously defined basic PDSE diagnostic data.

Actions to avoid recurrence

Enable the SMSPDSE1 address space when executing in a PDSESHARING(EXTENDED) environment.
Run with the SMSPDSE and SMSPDSE1 Monitor task enabled.
Automate the response to the IGW038A message.
