> Background Suspend / Resume Support

> MegaRAID provides a background Suspend or Resume Support feature that enhances the functionality where in the background operations running on a physical drive or a virtual drive can be suspended for some time, and resumed later using the Resume option.

> The background operations, including consistency-check, rebuild, replace, and background initialization are supported by an abort operation. If any operation is stopped before completion, it is considered to be aborted. An aborted operation cannot be resumed from the place where it was stopped.

> A suspended operation can be resumed later by using the Resume option, and the suspended operation resumes from the point where the operation was suspended last.

> To perform a suspend and resume operation, go to the Group Show Progress dialog, and perform the tasks mentioned below. You also can select Show Progress from the Manage menu, or select the More info link under the Background Operations portlet on the dashboard.

> The Group Show Progress dialog appears, as shown in the following figure. If Patrol Read is running, the Group Show Progress Patrol Read dialog appears.
