When are data encryption keys needed
After you setup the encryption environment, you will need data encryption keys to perform the following operations:
Adding drives
A Free key is needed for each drive to allocate a DEK key.
Replacing drives
A Free key is needed for each drive to change a DEK key.
Adding or replacing disk adapters
Six Free keys are needed for each disk adapter to create four CEK keys and two keys to register CEK keys.
Updating CEK keys
For VSP G200, VSP G400, G600, and VSP F400, F600: Two Free keys for each disk board (Four Free keys per storage system) are needed to change CEK keys.
For VSP G800 and VSP F800:
Two Free keys for each disk board (16 free keys per storage system) are needed to change CEK keys.
For VSP G1000:
Four Free keys for each disk adapter (32 Free keys per storage system) are needed to change CEK keys.
If a problem occurs during an operation, extra keys might be needed to recover from the problem.
