Issue/Introduction

SSM is not executing a DOWN_UP action for a task. Mode is ACTIVE:

OPS7914T SSM AUDIT: STCTBL.SSMTASK2 UPDATED by xxxxxx STATESET DESIRED_STATE=UP
OPS3730I STCTBL.SSMTASK2 RESOURCE: CURRENT=DOWN DESIRED=UP MODE=ACTIVE PMD=ACTIVE RMD=ACTIVE AMD=ACTIVE

Cause

A possible cause is that a prerequisite task is not UP

Resolution

Go to the OPSVIEW panel 4.11.2 and check the "Message" field. The string "Mprereq" indicates there is at least one missing prerequisite:

SSM Resource Status----------- SSSS -- O P S V I E W -------- Exceptions exist

You can use the "P" line command to identify which is (are) the missing prerequisite(s).

From a console, if the SSMCNTL command rule is enabled, you can use the command SSM DISPLAY JOB=xxxxxx to identify the prerequisites.

For example:

SSM DISPLAY JOB=SSMTASK2                                    

OPSNOTIFY SSM Display for Job = SSMTASK2
