query: Queries a database map.
reconcile: Reapplies the database drive mapping to the registry when the registry contents are damaged or dropped accidentally.

from_drive: The drive letter from which to map. This parameter is required for add and drop operations. If this parameter is not specified for a reconcile operation, db2drvmp reconciles the mapping for all drives.
to_drive: The drive letter to which to map. This parameter is required for add operations. It is not applicable to other operations.

Examples

To set up database drive mapping from F: to E: for NODE0, issue the following command:

   db2drvmp add 0 F E

To set up database drive mapping from E: to F: for NODE1, issue the following command:

   db2drvmp add 1 E F

Usage notes

Database drive mapping does not apply to table spaces, containers, or any other database storage objects.
Any setup of or change to the database drive mapping does not take effect immediately. To activate the database drive mapping, use the Microsoft Cluster Administrator tool to bring the DB2® resource offline, then online.
Using the TARGET_DRVMAP_DISK keyword in the DB2MSCS.CFG file will enable drive mapping to be done automatically.
