Haven't found this info anywhere, so I just add it FYI:
When installing additional OPAL-capable drives to the system simply follow for each drive the same full* procedure as for the 1st (using the same password).
After, all OPAL drives are unlocked when entering the password once at boot.
HTH
* you could omit the installation of the PBA boot image but it doesn't hurt and lets you unlock the drives in case your primary boot drive fails
