Initiating A Manual Rekey Session - Brocade Communications Systems StoreFabric SN6500B Administrator's Manual

Initiating a manual rekey session

You can initiate a rekeying session manually at your own convenience. All encryption engines in a
given HA cluster, DEK cluster, or encryption group must be online for this operation to succeed. The
manual rekeying feature is useful when the key is compromised and you want to re-encrypt existing
data on the LUN before taking action on the compromised key.
CAUTION
Do not commit this operation if there are any changes pending for the container in which the
rekey was started. If you attempt to do this, the system displays a warning stating that the
encryption engine is busy and a forced commit is required for the changes to take effect. A forced
commit in this situation will halt any rekey that is in-progress (in any container) and corrupt any
LUN that is running rekey at the time. There is no recovery for this type of failure.
1. Log in to the group leader as Admin or FabricAdmin.
2. Do LUN discovery by issuing the cryptocfg
3. Ensure that all encryption engines in the HA cluster, DEK cluster, or encryption group are online
4. Enter the cryptocfg
5. Check the status of the rekeying session.
