Hi. We are in process of decommissioning one of our NetApp environment. I have found KB
https://docs.netapp.com/us-en/e-series-santricity/sm-hardware/erase-drive.html

Question: What exactly does that erasure ? Is it simply delete data or zeroing the drives ?

it deletes the data and makes sure that data cannot be read in any way. Also to begin erase process,the drives should be unassigned from the configuration. so technically, it erases the data and zeros the drives

#

You can use the Erase option to prepare an unassigned drive for removal from the system. This procedure permanently removes data, ensuring that the data cannot be read again.
Before you begin

The drive must be in an Unassigned state.

#

in essence the process does zero drives because as a result of erasing drives the drives can be reused

When the Erase operation completes, the drives are available for use in another volume group or disk pool, or in another storage array.

Thanks. However, when I am trying to erase one last drive I am getting: "The requested operation cannot be completed as it contains all of the drives in the system and can lead to a loss of the overall system configuration. Please retry the operation with a smaller subset of the requested set of drives. (API 914)". Can it some

#

Why it could lead to a loss of system config ? Shouldn't be that on Controllers ? Is there a way to erase that last drive ?

This issue might need attention of NetApp Tech support.
