    Hi All,

     

    both primary and secondary APM MoMs got active after short outage of their shared disk.

     

    and as i dont have possibility to test/repeat this scenario right now and I would like to ask whether you can tell me

     

    1. how is it possible? = after the outage the primary started working as it had working before, however the secondary got the primary lock from some unknown reason for me

    2. when and how are the primary_em.lck and secondary_em.lck file created and deleted?

    3. should they contain any information, i.e pid (as they are empty)?

     

    thank you,

    stefan
