Disk sanitization limitations

Disk sanitization cannot be used with all configurations, models and disk drives.

The disk sanitization process has the following limitations:

• It is not supported in takeover mode for systems in an active/active configuration. (If a storage system is disabled, it remains disabled during the disk sanitization process.)
• It cannot be carried out on disks that were failed due to readability or writability problems.
• It cannot be carried out on disks that belong to an SEC 17a-4-compliant SnapLock volume until the expiration periods on all files have expired--that is, all of the files have reached their retention dates.
• It does not perform its formatting phase on ATA drives.
• It cannot be carried out on more than one SCSI Enclosure Service (SES) drive at a time.
• For V-Series systems, it is supported only with native disk shelves (not with array LUNs).
• It is not supported on some older disks.

  To determine if disk sanitization is supported on a specified disk, run the storage show disk command. If the vendor for the disk in question is listed as NETAPP, disk sanitization is supported.
