PARAMETERS

       handle	       an open handle returned from HBA_OpenAdapter(3HBAAPI)

       binding
		       HBA_GetFcpPersistentBinding()

			   a buffer to store the binding entries in.  The binding->NumberOfEntries member must	indicate  the  maximum	number	of
			   entries  that fit within the buffer. On completion, the binding->NumberOfEntries member will indicate the actual number
			   of binding entries for the HBA.  This value can be greater than the number of entries the buffer can store.

		       HBA_GetPersistentBindingV2()

			   a pointer to a HBA_FCPBINDING2 structure. The NumberOfEntries member will be the maximum number of entries returned.

		       HBA_SetPersistentBindingV2()

			   a pointer to a HBA_FCPBINDING2 structure. The NumberOfEntries member will be the number of bindings	requested  in  the
			   structure.

		       HBA_RemovePersistentBinding()

			   a  pointer  to a HBA_FCPBINDING2 structure.	The structure will contain all the bindings to be removed. The NumberOfEn-
			   tries member will be the number of bindings being requested to be removed in the structure.

       hbaPortWWN
		       HBA_GetPersistentBindingV2()

			   The Port WWN of the local HBA through which persistent bindings will be retrieved.

		       HBA_SetPersistentBindingV2()

			   The Port WWN of the local HBA through which persistent bindings will be set.

		       HBA_RemovePersistentBinding()
		       HBA_RemoveAllPersistentBindings()

			   The Port WWN of the local HBA through which persistent bindings will be removed.

DESCRIPTION

       The HBA_GetFcpPersistentBinding() function retrieves the set of mappings between FCP LUNs and SCSI LUNs that are  reestablished	upon  ini-
       tialization  or	reboot. The means of establishing the persistent bindings is vendor-specific and accomplished outside the scope of the HBA
       API.

       The HBA_GetPersistentBindingV2() function retrieves the set of persistent bindings between FCP LUNs and SCSI LUNs  for  the  specified  HBA
       Port  that are reestablished upon initialization or reboot. The means of establishing the persistent bindings is vendor-specific and accom-
       plished outside the scope of the HBA API. The binding information can contain bindings to Logical Unit Unique Device Identifiers.

       The HBA_SetPersistentBindingV2() function sets additional persistent bindings between FCP LUNs and SCSI LUNs for the specified HBA Port. It
       can  also accept bindings to Logical Unit Unique Device Identifiers. Bindings already set will remain set.  An error occurs if a request is
       made to bind to an OS SCSI ID which has already been bound. Persistent bindings will not affect Target Mappings until the OS,  HBA,  and/or
       Fabric has been reinitialized. Before then, the effects are not specified.

       The HBA_RemovePersistentBinding() function removes one or more persistent bindings. The persistent binding will only be removed if both the
       OS SCSI LUN and the SCSI Lun match a binding specifed in the arguments. Persistent bindings removed will not affect Target  Mappings  until
       the OS, HBA, and/or Fabric has been reinitialized. Before then, the effects are not specified.

       The HBA_RemoveAllPersistentBindings() function removes all persistent bindings. Persistent bindings removed will not affect Target Mappings
       until the OS, HBA, and/or Fabric has been reinitialized. Before then, the effects are not specified.

RETURN VALUES

       The HBA_GetFcpPersistentBinding() function returns the following values:

       HBA_STATUS_OK

	   The HBA was able to retrieve information.

       HBA_STATUS_ERROR_MORE_DATA

	   A a larger buffer is required.  The value of binding->NumberOfEntries after the call indicates the total number of  entries	available.
	   The caller should reallocate a larger buffer to accomodate the indicated number of entries and reissue the routine.

       HBA_STATUS_ERROR_NOT_SUPPORTED

	   The HBA handle specified by handle does not support persistent binding.

       In  the	event  that other error codes are returned, the value of binding->NumberOfEntries after the call should be checked, and if greater
       than the value before the call, a larger buffer should be allocated for a retry of the routine.

       The HBA_GetPersistentBindingV2() function returns the following values:

       HBA_STATUS_OK

	   The HBA was able to retrieve information.

       HBA_STATUS_ERROR_MORE_DATA

	   A a larger buffer is required.  The value of binding->NumberOfEntries after the call indicates the total number of  entries	available.
	   The caller should reallocate a larger buffer to accomodate the indicated number of entries and reissue the routine.

       HBA_STATUS_ERROR_ILLEGAL_WWN

	   The Port WWN hbaPortWWN is not a WWN contained by the HBA referenced by handle.

       HBA_STATUS_ERROR_NOT_SUPPORTED

	   The HBA handle specified by handle does not support persistent binding.

       The value of binding remains unchanged. The structure it points to contains binding information. The number of entries returned is the min-
       imum between the number of entries specifed in the binding argument and the total number of bindings.

       The HBA_SetPersistentBindingV2() function returns the following values.

       HBA_STATUS_OK

	   The HBA was able to set bindings.

       HBA_STATUS_ERROR_ILLEGAL_WWN

	   The Port WWN hbaPortWWN is not a WWN contained by the HBA referenced by handle.

       HBA_STATUS_ERROR_NOT_SUPPORTED

	   The HBA handle specified by handle does not support persistent binding.

       The value of binding remains unchanged. The success or failure of each Persistent binding set is indicated in  the  Status  member  of  the
       HBA_FCPBINDINGENTRY2 structure.

       The HBA_RemovePersistentBinding() function returns the following values:

       HBA_STATUS_OK

	   The HBA was able to retrieve information.

       HBA_STATUS_ERROR_ILLEGAL_WWN

	   The Port WWN hbaPortWWN is not a WWN contained by the HBA referenced by handle.

       HBA_STATUS_ERROR_NOT_SUPPORTED

	   The HBA handle specified by handle does not support persistent binding.

       The  value  of  binding	remains  unchanged. The success or failure of each Persistent binding set is indicated in the Status member of the
       HBA_FCPBINDINGENTRY2 structure.

       The HBA_RemoveAllPersistentBindings() function returns the following values:

       HBA_STATUS_OK

	   The HBA was able to retrieve information.

       HBA_STATUS_ERROR_ILLEGAL_WWN

	   The Port WWN hbaPortWWN is not a WWN contained by the HBA referenced by handle.

       HBA_STATUS_ERROR_NOT_SUPPORTED

	   The HBA handle specified by handle does not support persistent binding.

BUGS

       The HBA_GetFcpTargetMapping(3HBAAPI) and HBA_GetFcpPersistentBinding() functions do not take a portindex to  define  to	which  port  of  a
       multi-ported  HBA  the  command should apply. The behavior on multi-ported HBAs is vendor-specific and could result in mappings or bindings
       for all ports being intermixed in the response buffer.  SNIA version 2 defines a HBA_GetFcpTargetMappingV2() that takes a Port  WWN  as	an
       argument. This fixes the bug with multi-ported HBAs in HBA_GetFcpTargetMapping().
