the appropriate security key must also be imported to the new storage array.
Otherwise, the data on the security enabled physical disks that were moved is
inaccessible.
For more information on validating the security key, see the PowerVault
Modular Disk Storage Manager online help topics.
Unlocking Secure Physical Disks
You can export a security-enabled disk group to move the associated physical
disks to a different storage array. After you install those physical disks in the
new storage array, you must unlock the physical disks before data can be read
from or written to the physical disks. To unlock the physical disks, you must
supply the security key from the original storage array. The security key on the
new storage array is different and cannot unlock the physical disks.
You must supply the security key from a security key file that was saved on the
original storage array. You must provide the pass phrase that was used to
encrypt the security key file to extract the security key from this file.

online help topics.
Erasing Secure Physical Disks
In the AMW, when you select a security enabled physical disk that is not part
of a disk group, the Secure Erase menu item is enabled on the Physical Disk
menu. You can use the secure erase procedure to re-provision a physical disk.
You can use the Secure Erase option if you want to remove all of the data on
the physical disk and reset the physical disk security attributes.
CAUTION: Possible loss of data access – The Secure Erase option removes all of
the data that is currently on the physical disk. This action cannot be undone.
Before you complete this option, ensure that the physical disk that you have
selected is the correct physical disk. You cannot recover any of the data that is
currently on the physical disk.
After you complete the secure erase procedure, the physical disk is available
for use in another disk group or in another storage array. For more information
on the secure erase procedure, see the PowerVault Modular Disk Storage
Manager online help topics.
