We use the automatic update of LLA by PDSMAN for linklist pds. Today we did a job using IEBCOPY to copy a pgm from a pds to another which is in the linklist. The LLA wasn't refreshed and we don't get the PDSMLLA message.
In your PDSMINIT file you have the following settings:
$LLA LIB=-LNKLST-
UPDATELLA=Y
NOTIFY=Y ----> This should produce the message when the update is completed
MONITORMSG=Y
LRDRUPDT=Y
It appears you have everything set correctly but the message is still not issued.
Issue the following command from the console. F PDSMAN,NEWRULES
This will refresh the rules and all should be good.
