Dell EMC PowerVault MD 34XX/38XX Series Storage Arrays Administrator's Guide

Starting snapshot rollback

1. From the AMW, select the Storage & Copy Services tab.
2. Do one of the following:
   • Select a snapshot image of a base virtual disk and then select Copy Services > Snapshot Image > Rollback > Start.
   • Select a consistency group snapshot image, and then select Copy Services > Consistency Group Snapshot Image > Rollback > Start.
   Depending on your selection, either the Confirm Rollback Snapshot Image or the Confirm Rollback Snapshot Image window is displayed.
3. If you are starting the rollback operation from a consistency group snapshot image, select the member virtual disks from the member virtual disks table that you want to rollback; otherwise skip to step 4.
4. In the Rollback priority area, use the slider bar to set a priority for the rollback operation.
   • There are five priority rates available: lowest, low, medium, high, and highest.
   • If the priority is set at the lowest rate, I/O activity is prioritized and the rollback operation takes longer time to complete.
   • If the priority is set at the highest priority rate, the rollback operation is prioritized, but I/O activity for the storage array may be affected.
5. To confirm and start the rollback operation, type yes in the text box, and click Rollback.
   You can view the progress of the rollback operation in the Properties pane when you select the base virtual disk or the consistency group member virtual disk in the Logical pane.
