Frequently asked questions...
- 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, System Manager displays a list of all the eligible volumes for that mirrored pair. Any volumes that are not eligible to be used do not display in that list. - 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, System Manager displays a list of all the eligible volumes for that mirrored pair. Any volumes that are not eligible to be used, do not display in that list. - Synchronous mirroring - What do I need to know before creating a mirrored pair?
Your storage array must contain at least one mirror consistency group. - 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. - Why do I see Not Available values displayed in the table?
The table lists Not Available values when the data located on the remote storage array is not available to be displayed. To display the remote storage array data, launch ThinkSystem System Manager from ThinkSystem SAN Manager .
