 DESCRIPTION
      The vxddladm utility is an administrative interface to the dynamic
      array support facility of the Device Discovery Layer(DDL).  This
      utility lists the types of arrays supported, adds or removes array
      support from DDL, and allows dynamic addition of JBOD support for
      disks from different vendors.  It additionally lists supported JBODs,
      and allows addition or removal of JBOD support.  The vxddladm utility
      is also used to customize the set of array libraries that can
      participate in device discovery.

 KEYWORDS
      addjbod	Adds disks having the specified VID and PID in the JBOD
		category (DISKS).

      excludearray
		Excludes the specified array libraries from participating in
		device discovery. This does not remove the specified
		libraries from the system. As a result, vxddladm listsupport
		displays the corresponding disk arrays.

      includearray
		Includes the array libraries previously excluded by
		excludearray.  These can be used for device discovery
		operations.

      listexclude
		Lists information about the disk array libraries excluded
		from device discovery functionality.

      listjbod	Lists information about the types of disks supported in JBOD
		category (DISKS).

      listsupport
		Lists information about supported disk arrays.

      rmjbod	Removes disk with the specified VID and PID from the JBOD
		category (DISKS).  These disks are categorized as
		OTHER_DISKS and are not multipathed.

 ATTRIBUTES
      The attribute all selects all objects for an operation.

      Other attributes are specified using the format attribute=value.

      arrayname Name of the array on which the operation is performed.

      length	Size of the field containing unique disk serial number.

      libname	Name of the array library on which the operation has to be
		performed.

      offset	Offset on the page code.

      opcode	SCSI opcode.

      pagecode	Page code for SCSI command.

      pid	Product ID of the disk array.

      vid	Vendor ID of the disk array.

      Note: The value for vid and pid should be taken from the output of the
      vxddladm listsupport command. These values may be different from the
      actual vid and pid values of the disks within an array.
