Performing Secure Erase of Data on Storage Disks
With this release, you can securely erase data from storage devices. Running the
secure erase tool deletes the data on the storage disk permanently.
You may want to consolidate storage disks between appliances. For example, you can
use X7-2 disks on X6-2 models, and may want to consolidate all X6-2 disks on one
system, and use all new X7-2 storage disks on another system. In such cases, use
secure erase to erase headers from disks before re-imaging the disks, since the
storage disks across the appliances may have different partition ratios.
Note:
Running the secure erase tool removes data from storage disks
permanently. If you have any data on the disk, then take a backup of your
storage disk before running the secure erase tool.
Follow the steps to run the secure erase tool:
