Bug ID 6880106: When the Logical Domains Manager (ldm) starts up, it initializes any cryptographic units that are present in the control domain for use in securing migration operations. If a cryptographic unit is added to the control domain at any point after ldm starts, those cryptographic units are not utilized for migration. This situation might negatively impact the time it takes for a migration operation to complete.
Workaround: Restart ldmd to force it to reinitialize its use of the cryptographic units in the primary domain. Run the following command:
# svcadm restart ldmd
