- How does asynchronous mirroring differ from synchronous mirroring?
The Asynchronous Mirroring feature differs from the Synchronous Mirroring feature in one essential way: it captures the state of the source volume at a particular point in time and copies just the data that has changed since the last image capture. - Synchronous mirroring - Why don’t I see all my volumes?
When you are selecting a primary volume for a mirrored pair, a list shows all the eligible volumes. - Synchronous mirroring - Why don’t I see all the volumes on the remote storage array?
When you are selecting a secondary volume on the remote storage array, a list shows all the eligible volumes for that mirrored pair. - Synchronous mirroring - What do I need to know before creating a mirrored pair?
You configure mirrored pairs in the SAN Manager interface, and then manage the pairs in System Manager. - What impact does synchronization priority have on synchronization rates?
The synchronization priority defines how much processing time is allocated for synchronization activities relative to system performance. - Why is it recommended to use a manual synchronization policy?
Manual resynchronization is recommended because it lets you manage the resynchronization process in a way that provides the best opportunity for recovering data.
