Fast zeroing of drives

Beginning in ONTAP 9.4, you can automatically and quickly zeros drives (both SSDs and HDDs) before provisioning without experiencing long wait times..

For systems that are freshly installed with ONTAP 9.4 or later or systems that are reinitialized with ONTAP 9.4 or later, drive zeroing takes place automatically and is complete in seconds.

If you need to manually zero a drive, you can use one of the following methods:

The fast zeroing enhancement does not support systems upgraded from a release earlier than ONTAP 9.4.

If any node on the cluster contains an aggregate with fast-zeroed drives, then you cannot revert the cluster to ONTAP 9.2 or earlier.
