IBM XIV - Creating a Mirroring Definition

v SYNC_MIRROR_DOES_NOT_USE_SCHEDULE
Definition of Synchronous Mirror does not require a Schedule object to be
specified.
v VOLUME_BELONGS_TO_MIRRORED_CONS_GROUP
Volume mirror is part of Consistency Group mirror.
v INTERVAL_SHOULD_BE_SHORTER_THAN_RPO
Schedule interval must me shorter than the RPO.
The newly defined schedule has to be shorter than the RPO.
Creating a Mirroring Definition
Creates remote mirroring coupling.
