3-10 ServeRAID-MR10is SAS/SATA Controller Characteristics
3.4.3 Archiving Keys
You can securely archive the Security Keys from the controller(s) to a file
in a repository location (typically not in the array) of your choice for
storage, backup, and so on. IBM recommends that you archive your
Security Keys for any array that is operating with a single controller.
3.4.4 Virtual Disk Migration
Drive migration is the transfer of a set of physical drives in an existing
configuration from one controller to another. The drives must remain on
the same channel and must be reinstalled in the same order as in the
original configuration.
An encrypted volume group can be migrated from one array to another.
If a secured configuration is moved to a controller that does not support
encryption, the configuration is locked and foreign, and it cannot be
imported.
Note: Drive roaming and drive migration cannot be supported at
the same time.
To migrate encrypted volume groups, perform the following steps:
Step 1. Generate a Security Key on the destination controller. If a
Security Key already exists, this step is not necessary.
Step 2. Move the drives to the destination array.
Step 3. Enter the Security Key string of the migrated drives.
Step 4. Import the configuration.
Note: For the procedures used to import a foreign configuration,
refer to the
ServeRAID-MR Software User’s Guide .
3.4.5 Modifying the Keys
You can regenerate the Security Key for an array without making the
data inaccessible. Through the Host SW Client, you can perform a
password-protected operation to regenerate the Security Key. These
operations are an option when you think the security of the array is under
threat because the Security Key might have been compromised.
