Mirroring to standby and iRule node/pool ability

Hi

 

 

I am unsure of a couple of aspects to do with iRules

 

 

- Are data group values mirrored to the standby?

 

- Are global variables/arrays mirrored to the standby?

 

- Are session sub-tables created in irules mirrored to the standby? [looks like yes, but just verifying]

 

- Can iRules add/remove and set ratios to node/pool members? [i think no, and need icontrol or external script]

 

 

Thanks

  • Hi

     

     

    No reply to my question yet, can someone verify the following answers that I have come up with myself?

     

     

     

    - Are data group values mirrored to the standby that are modified directly by irules?

     

    No. Would need to "sync config" to be mirrored.

     

     

     

    - Are global variables/arrays mirrored to the standby?

     

    No.

     

     

    - Are session sub-tables created in irules mirrored to the standby?

     

    Yes.

     

     

    - Can iRules add/remove and set ratios to node/pool members?

     

    No, this would require icontrol or external script. [Script would also need to 'sync' config? to have standby running same nodes/ratios]

  • Hi Anthony,

     

    These are all correct responses to your questions.

     

     

    To Further add to your last question

     

     

    - Can iRules add/remove and set ratios to node/pool members?

     

    There are 2 directories where the configsync will pick up files (http://support.f5.com/kb/en-us/solutions/public/8000/500/sol8522.html). Otherwise you have to manually copy the External Scripts to the standby LTM.
