If you do not add a second virtual hard disk to the Avaya Breeze® platform cluster node before installing Presence Services, then, by default, the Presence Services software creates an alternate attachment store in the /var partition on the Avaya Breeze® platform server. Presence Services creates an alternate attachment store if a second hard disk is not found. You can verify if the alternate store exists by using the Avaya Breeze® platform or Presence Services server.
