ONTAP 9.14

to Japanese version

Fast zeroing of drives

On systems freshly installed with ONTAP 9.7 or later and systems reinitialized with ONTAP 9.7 or later, fast zeroing is used to zero drives.

With fast zeroing, drives are zeroed in seconds. This is done automatically before provisioning and greatly reduces the time it takes to initialize the system, create aggregates, or expand aggregates when spare drives are added.

Fast zeroing is supported on both SSDs and HDDs.

ONTAP 9.7 or later must be freshly installed or the system must be reinitialized.

If you need to manually zero a drive, you can use one of the following methods. In ONTAP 9.7 and later, manually zeroing a drive also takes only seconds.
