Unfortunately, E-Series does not have a function to write all zeroes to a drive.
The drive initialization function on E-Series does not write all zeroes to the drive. Instead, the function removes the configuration information from a drive that has already been moved from one array to a new array.
You will not be able to initialize a drive in its native array.
The drive initialize function will only work on drives that meet all of the following criteria:
have been moved from one array to another array
have pre-existing volume configuration information
have been marked as FAILED or INCOMPATIBLE by the new array
If you need to write all zeroes to the drives, I can propose a workaround. You would have to create a RAID 0 volume group and volume and would have a host-side application write zeroes to the volume. Use RAID 0 so the array does not have to perform parity calculations. If you make several smaller volumes as opposed to one large volume, your application might be able to write to several volumes at once which would make the process faster. After your application finishes writing all zeroes to each volume, you can delete the volumes and volume groups.
