Disk Wipe Results

After all jobs have completed, a summary screen displays.

For a system with external arrays, the results screen is listed by Disk Array Name. To see more information on each LUN/Volume in the array, select a button in the Disk Array column.

For a system with internal storage, the results screen is listed by Node Name. To see more information on the devices wiped on a node, select a button in the Node Name column.

If any devices were unsuccessfully erased, they can be retried. By default, all failed jobs are selected to be retried. Clear the checkbox next to a LUN/Volume/Device to stop the retry. A successfully-erased device cannot be retried.
