Disk sanitization can take time to complete. If disk sanitization is interrupted by user intervention or an unexpected event such as a power outage, Data ONTAP takes certain actions to prevent corrupted disks if necessary. You must restart sanitization from the beginning after the interruption has been resolved.
If the sanitization process is interrupted by power failure, system panic, or a user-invoked disk sanitize abort command, the disk sanitize command must be re-invoked and the process repeated from the beginning in order for the sanitization to take place.
If the formatting phase of disk sanitization is interrupted, Data ONTAP attempts to reformat any disks that were corrupted by the interruption. After a system reboot and once every hour, Data ONTAP checks for any sanitization target disk that did not complete the formatting phase of its sanitization. If such a disk is found, Data ONTAP attempts to reformat that disk, and writes a message to the console informing you that a corrupted disk has been found and will be reformatted. After the disk is reformatted, it is returned to the hot spare pool. You can then rerun the disk sanitize command on that disk.
