    What is the best practice for adding a downtime page for SDM 14.1?

     

    We are going to be upgrading Service Catalog soon, which requires us to quiesce Service Desk.  We would a downtime page to tell users the system is down, ETA for service restoration etc.

     

    SDM:

    14.1, Adv Availability

    F5 load balancer for user traffic on application servers

    IIS 8 running on port 80

    10+ application servers

     

    I was thinking of using the IIS URL rewrite module to redirect to a maintenance page, but wanted to see what the user groups think.  I would prefer to automate turning on/off the maint page which can be troublesome with the URL rewriter.

     

    Thanks,

    I would think using the F5 would be the best way since there is a procedure for adding a custom health monitor here:

    How to Configure the F5 Load Balancer for CA Service Desk Manager - CA Service Management - 14.1 - CA Technologies Docum… 

     

    Then a custom iRule could be created using HTTP::redirect to the Downtime page you create for this purpose.  When SDM comes out of quiesce, then the F5 would return to normal load balancing?

    HI J_W, Paul,

     

    Yes, we internally came to the same conclusion after I posted my question.  I am marking this as answered/correct.

     

    Thanks,

    To clarify, the Health Monitor provided by CA is used with the F5 to determine if a SDM application server should be marked as  up or down in the pool.  The F5 has a feature (not provided by CA) that if all hosts are marked down then redirect user to maintenance page.

     

    Thanks,
