I must be bored since I’m posting again.
A colleague asked me to change the failed value of a TCP probe today. It was no big deal, but, when I looked to see the status of the change, I noticed interesting stati of the RIPs.
switch#sh mod csm 7 probe name TCP80-PROBE detail probe type port interval retries failed open receive --------------------------------------------------------------------- TCP80-PROBE tcp 80 20 3 120 10 Description: Quick fail recovery recover = 3 real vserver serverfarm policy status ------------------------------------------------------------------------------ 192.168.1.45:80 VS01 FARM01 (default) ??? 192.168.1.44:80 VS01 FARM01 (default) ??? 192.168.1.43:80 VS01 FARM01 (default) ??? 192.168.1.42:80 VS01 FARM01 (default) ???
It seems that when a change is made to a probe, the CSM discards the state of the probe and starts over. If you catch it before the first probe is finished, you’ll get a status of “???”. I’m just picturing the CSM saying “Uhh…I…don’t…know”.
It quickly cleared back to “OPERABLE”, and my morning fun was gone. :(
