An administrator receives an error on an XtremIO array while performing snapshot refreshes to a production volume. What is a potential cause for this issue?

ARefresh of the production volume is not supported

BVolume was not unmapped on the XtremIO cluster

COnly snapshot-to-snapshot refresh is supported

DVolume was not unmounted on the host

Show Suggested Answer

Suggested Answer: D

The workflow for refreshing XtremIO Snapshots, containing Oracle Database files, consists of the following five simple steps:

1. Shut down the database instances with files in the target Snapshot Set.

2. Dismount the ASM disk group (or file systems) involved.

3. Refresh the Snapshot via XtremIO GUI (or CLI or RESTful API).

4. Mount the ASM disk groups (or file system) involved.

5. Start the database instances.

This entire workflow is measured in seconds (not minutes).
