6 PREFER, TOOLS, Specify a preferred path for DSA disks. ! 9         The PREFER command specifies a preferred path for 7      DSA disks. This includes RA-series disks and disks :      accessed through the MSCP server. If a preferred path9      is specified for a disk, the MSCP disk class drivers 8      (DUDRIVER and DSDRIVER) use the path as their first9      attempt to locate the disk and bring it on line as a <      result of a DCL command MOUNT or failover of an already:      mounted disk. In addition, you can initiate failover 8      of a mounted disk in order to force the disk to the:      preferred path, or to use load-balancing information -      for disks accessed through MSCP servers. 
