Issue/Introduction

The NetMaster region issues a D M=CPU command during the initialization phase. What is the reason that command is issued?

Environment

Release : 12.2

Component : CA NetMaster Network Management for TCP/IP

Resolution

The reason NetMaster does this is to try to ascertain the CSS and MIF information for the Local system, which is then used for correlating information required by Netmaster OSA monitoring. PTF RO98166 introduced this behaviour.

Basically, without this information, monitoring of OSA SNMP based attributes fails when running under LPARs defined with LCSS IDs (Logical Channel Subsystem ID) not equal to zero.   

The pair of values (LCSS ID + MIF ID) represents an LPAR which is then used in SNMP requests to determine the appropriate OSA values.

Additional Information

If NetMaster is not authorized to issue this command, CA Top Secret returns the following messages:
D M=CPU
