Default AIX paramaters

I understand the values for configuration settings like:

MAX_XFER_SIZE

NUM_CMD_ELEMS

QUEUE_DEPTH

Are set by loading the EMC ODM.

The defaults are not documented in the EMC documentation. If performing a health check on an AIX environment connected to VMAX, how do I confirm that the settings are right (have not been altered fro default)?

Can I reload the same ODM version over an existing one to set any of the above valued back to default?
