NAME

       vparutil - get and set SCSI parameters for SCSI controllers from a virtual partition

SYNOPSIS

       dev_path

       dev_path

       dev_path scsi_id] scsi_rate]

DESCRIPTION

       The  command gets and sets SCSI parameters for SCSI controllers within a running virtual partition.  When setting the SCSI parameters using
       the option, the virtual partition which owns the specified SCSI controller must be in the down state.  If not, the command will	fail  with
       the appropriate error code.

       The  SCSI parameters for a given SCSI controller must first be set (from the firmware BCH prompt or using the option) before the parameters
       can be retrieved using the option.

       The command is allowed on Itanium(R)-based platforms for compatibility.	No action is taken for the command.

   Options
       recognizes the following command-line options:

       Deletes an entry for the specified SCSI controller at
	     dev_path from the SCSI table.

       Gets the SCSI parameters for the specified SCSI controller at
	     dev_path.

       Sets the SCSI parameters for the specified SCSI controller at
	     dev_path.

   Operands
       recognizes the following command-line operands:

       dev_path        The device path of the SCSI controller.

       id	       The SCSI ID for the specified controller (defaults to 7).

       rate	       The SCSI rate for the specified controller.  This parameter can have one of two values: for the corresponding fast wide and
		       ultra wide SCSI interfaces.

   Note
       For managing SCSI controllers, use corresponding SCSI utilities.  For further information refer to

SECURITY RESTRICTIONS

       This command is restricted to processes owned by superuser.

       When  virtual  partition  flexible administrative capability is enabled, only a Designated-Admin vPar can set SCSI parameters for SCSI con-
       trollers.

EXAMPLES

       Set the SCSI ID for controller at 0/0/2/0 to 3 with the fast wide rate:

RETURN VALUE

       Successful.
       Invalid SCSI controller specification.
       Invalid SCSI ID.
       Could not communicate with virtual partition monitor.
       Virtual partition which owns SCSI controller is not in down state.
       Internal firmware call failed.
       Other error.

scsi_address(9S)                                            Data Structures for Drivers                                           scsi_address(9S)

NAME

       scsi_address - SCSI address structure

SYNOPSIS

       #include <sys/scsi/scsi.h>

INTERFACE LEVEL

       Solaris architecture specific (Solaris DDI)

DESCRIPTION

       A scsi_address structure defines the addressing components for a SCSI target device. The address of the target device is separated into two
       components: target number and logical unit number. The two addressing components are used to uniquely identify any  type  of  SCSI  device;
       however, most devices can be addressed with the target component of the address.

       In  the case where only the target component is used to address the device, the logical unit should be set to  0. If the SCSI target device
       supports logical units, then the HBA must interpret the logical units field of the data structure.

       The pkt_address member of a scsi_pkt(9S) is initialized by scsi_init_pkt(9F).

STRUCTURE MEMBERS

       scsi_hba_tran_t   *a_hba_tran;  /* Transport vectors for the SCSI bus */
       ushort_t          a_target;     /* SCSI target id */
       uchar_t           a_lun;        /* SCSI logical unit */

       a_hba_tran is a pointer to the controlling HBA's transport vector structure. The SCSA interface uses  this  field  to  pass  any  transport
       requests from the SCSI target device drivers to the HBA driver.

       a_target is the target component of the SCSI address.

       a_lun is the logical unit component of the SCSI address. The logical unit is used to further distinguish a SCSI target device that supports
       multiple logical units from one that does not. The makecom(9F) family of functions use the a_lun field to set the logical unit field in the
       SCSI CDB, for compatibility with SCSI-1.
