partition smkrollover

This command, with the -start option, moves the current primary SMK to the Rollover location, and generates a new Primary SMK.

If you just wanted to generate a fresh SMK, and no external SKS blobs are encrypted with the previous SMK, then you can issue the comand again with the -end option, and the task is finished.

If you are performing a rollover of an active SMK (as you might do, in compliance with your organization's key-rotation policy), then - immediately after partition smkrollover -start - you would insert and re-extract all SKS blobs that are encrypted by the old SMK. The HSM recognizes which SMK was used to encrypt a blob, and if it is the rollover SMK (or an SMK from a previous HSM generation, currently in the appropriate 'legacy' SMK location), it uses that SMK for the insertion. [Re-]extraction always uses the Primary SMK.

When all desired blobs have been re-extracted, the partition smkrollover -end command finishes the process.

CAUTION!   The partition smkrollover -end command deletes the SMK from the Rollover space of the current partition, leaving only the new SMK in the Primary space. If you have exported any SKS blobs using the old SMK, that you have not re-extracted with the new Primary SMK, then those blobs can never be inserted again, unless you have retained a backup of the old SMK.

Syntax

partition smkrollover [-start] [-end] [-force]

Argument Shortcut Description
-end -e End SMK rollover and delete the Rollover SMK.
-force -f Force the action without prompting for confirmation (useful when scripting commands).
-start -s Start SMK rollover, moving the pre-existing SMK to the Rollover space, and creating a new SMK in the Primary SMK space.

Example

lunacm:> partition smkrollover -start

        You are about to rollover the SMK.
        Are you sure you wish to continue?

        Type 'proceed' to continue, or 'quit' to quit now -> proceed

Command Result : No Error

Between issuing the -start and -end commands, insert and re-extract any SKS blobs that were encrypted/extracted with the old SMK, so that they are now encrypted with the new (Primary) SMK and stored externally. 

lunacm:> partition smkrollover -end

        You are about to rollover the SMK.
        Are you sure you wish to continue?

        Type 'proceed' to continue, or 'quit' to quit now -> proceed

Command Result : No Error
