How to efficiently delete a node from LTM?

Hi Sergei,

if you have figured out the related pools you can use tmsh as well to delete a specific pool member:

tmsh modify ltm pool  members delete { : }

Combining this with the answer from Michael J you can use a one liner to parse all pools and create the syntax to modify all pools on your system. Just replace the value of node with the node´s name:

node="10.131.131.5"; tmsh list ltm pool one-line | grep -E "${node}:[[:alnum:]]" | \
sed -r 's/ltm pool ([^ ]+).*members.*('${node}':[[:alnum:]]+).*/tmsh modify ltm pool \1 members delete { \2 }/g'

By adding "bash -x" the output will be executed immediately. Please be very careful!:

node="10.131.131.5"; tmsh list ltm pool one-line | grep -E "${node}:[[:alnum:]]" | \
sed -r 's/ltm pool ([^ ]+).*members.*('${node}':[[:alnum:]]+).*/tmsh modify ltm pool \1 members delete { \2 }/g' | bash -x

As this only modifies the running configuration you need to save to startup configuration afterwards and config-sync:

tmsh save sys config  
tmsh run cm config-sync to-group 

The syntax above can be enhanced to support administrative partitions and routing domains. Please let me know, if this is an additional requirement.

Thanks, Stephan

PS: Of course I recommend a config backup before applying all kind of change ...
