How to Automate actions!

It could be scripted, what's the actual requirement? Do you just want to a a new server to a large number of existing pools?

yes!

I'm no bash scripting expert but how about something like this (which I'm sure could be greatly improved but will still save you lots of time);

!/bin/bash

NEWMEMBERIP=1.1.1.1
NEWMEMBERNAME=testnode
NEWMEMBERPORT=8080

tmsh create ltm node $NEWMEMBERNAME address $NEWMEMBERIP
tmsh modify ltm pool pool1name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}
tmsh modify ltm pool pool2name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}
tmsh modify ltm pool pool3name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}
tmsh modify ltm pool pool4name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}
tmsh modify ltm pool pool5name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}
tmsh modify ltm pool pool6name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}
tmsh modify ltm pool pool7name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}
tmsh modify ltm pool pool8name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}
tmsh modify ltm pool pool9name members add \{ $NEWMEMBERNAME:$NEWMEMBERPORT \}

exit 0
