Netscaler 9.3 - How to Drain Service

disabling the "down state flush" checkbox should do the trick.

Thanks...

I have been doing a lot on research on this since I have to do this process next week. In 9.3 I have read that "Grace Full Shutdown" was included and if you select this and do not enter in a timeout value the service will one be disable after all existing connections are released...

Is this true

sorry,
i use Netscaler 10.x only. So i can't test "Gracefull Shutdown".
But it seems booth are the same.

Thanks i will be trying this tomorrow and let you know how i make out

Before I used the grace full shut down option I check the number of connection to the server is question and it had 12 connection with varying idle times.

Under Load Balance -> Services and cliced on disable  and select Grace full shut down and gave it a timeout period of 900 seconds.

I was surprise because once I clicked OK the service was listed as Out of service and there no more connection on the server.

Do I do this process correctly?

that's the way as explained here:
http://support.citrix.com/proddocs/topic/netscaler-load-balancing-93/ns-lb-clienttraffic-gracefulshutdown-tsk.html

check the cli-output and compare the resulting settings with the article ...

I will try it and let you know.

Is it possible the server was placed offline imminently because the connections were idle?

possible ...
i'll ask a CAG / Netscaler trainer next week. He should know the "old" CAG also.

Thanks it would be interesting to see what the trainer says

Thanks for check on this so the possible reason why all connection were dropped then is becuase they were idle????

this or a bug ...
