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. If Presence Services is installed before adding the second virtual hard disk, then you must manually move the alternate attachment store to the second virtual hard disk so that the second hard disk has no interaction with other Breeze sub-systems.
