    Hi Yusuf

     

    UMP is not included in HA failover out of box currently although there are some custom solutions available  .Only UMP load balancing is supported out of box when you have multiple UMP setup.

     

    Below Tec note will provide more info on the setup on using HA probe for UIM failover.

    Hi Frankin,

     

    I haven't configured UMP HA. Only UIM HA is configured and as per that whenever my Primary UIM will go down the secondary has to come up and all the other service should start automatically.

     

    In my case all the things are ok even UMP is loading after fail-over of UIM but i am unable to login into that, it is not accepting the credential.

    Hi Yusuf

     

    Are you using LDAP?  If os you need to check your HA hubs settings. You need to configure this hub to have a connection to ldap.

    If you have the HA hub configured as ldap proxy then it will be forwarding the ldap requests to the primary hub which will of course fail as the Primary hub is down

     

    Hope this helps

    Hi All,

     

    Thanks for your answer.

     

    Still having some queries can you please give me your suggestion on them:

     

    1) Do i need a separate UMP Server to run UMP_faiolover script. If yes then what would be the  prerequisite ?

    2) where i need to add this script and will it be able to communicate with both server UIM primary and seconday ?

    Hi Team,

     

    Thanks for your updates....

     

     

    I did the same i deployed that script in NAS of secondary UIM server but still i am unale to load UMP.

     

    When we checked the raw config. of UMP Wasp probe still all the probe were pointing to primary HUB because of that it couldn't load.

     

    After fail-over all the UIM primary probes have to point to secondary UIM server hen only UMP will load but it is not happening.

     

    Please me know how the same can be done.

    Hi,

    Do you see the alarms generated by the script in your console on the secondary node?

    If not, see all comments in: UMP failover

    Hi Team,

     

    Thanks for your updates....

     

     

    But Still UMP fail over is not happening.

     

    After Primary UIM down, probes are unable to point on secondary UIM.

     

    We are not getting any error related to script so unable to find the exact issue that where are we lagging and how to troubleshoot this.

     

     Is there any alternate way to check the same ? or where we can check the scripts related logs.

     

    If we would be able to check scripts logs, we can try to troubleshoot this issue on basis on logs.

     

     

    Please let me know suggestion.

     

    Regards
