Depending on the setup of the priority group activation, lowing the priority of a pool member could cause the LTM to add members from another priority group. Example, say your pool is setup with the config below. If you move node3 from priority-group 10 to priority-group 5, because there are now only 2 active members in the priority-group 10 the LTM will include all members from priority-group 5.
If you are looking to move the traffic off a pool member for maintained, the fastest way is to “Force Office” the pool member, which is only accessible from the pool member page. "Local Traffic...Pools......Members Tab..." Select Force Offline...Click Update. Forcing offline the pool member allows only active connections to that pool member. If you “Disable” a pool member from the pools member tab, this allows persistence and active connection to continue to that disabled pool member. "Local Traffic......Members" Select Pool members you want to disable...Click Update.
Example config:
ltm pool priorty-group {
members {
node1:http {
address 10.0.0.1
priority-group 10
session monitor-enabled
state down
}
node2:http {
address 10.0.0.2
priority-group 10
session monitor-enabled
state down
}
node3:http {
address 10.0.0.3
priority-group 10
session monitor-enabled
state down
}
node4:http {
address 10.0.0.4
priority-group 5
session monitor-enabled
state down
}
node5:http {
address 10.0.0.5
priority-group 5
session monitor-enabled
state down
}
node6:http {
address 10.0.0.6
priority-group 5
session monitor-enabled
state down
}
}
min-active-members 3
monitor http
}

- ERLomboy_27803Jan 22, 2016NimbostratusHi Kroestel, Thanks for your feedback! It seems it's better to force the member offline that lowering priority? do you agree? We have 4 nodes in the pool and the minimum number of members is set to 1? Is it possible that the reason it's not draining the connections is because of stale/idle connections?
