You can enable Drive Security for a pool or volume group to prevent unauthorized access to the data on the drives contained in the pool or volume group. Read and write access for the drives is only available through a controller that is configured with a security key.
If you want to use Drive Security, select a pool or volume group that is secure-capable. A pool or volume group can contain both secure-capable and non-secure-capable drives, but all drives must be secure-capable to use their encryption capabilities.
After enabling security, you can only remove it by deleting the pool or volume group, and then erasing the drives.
