Delete Persistence records for a node in LTM

In v11, you can use the show command in tmsh to find the records, ensuring they're the correct ones, then change 'show' to 'delete':

show ltm persistence persist-records node-addr 1.2.3.4

Then:

delete ltm persistence persist-records node-addr 1.2.3.4

If you delete members from the pool, surviving members will be chosen for load balancing even if there is persistence to the DOWN members.
