sdi_edt(D4I)                                            sdi_edt(D4I)


       NAME
             sdi_edt - internal EDT device definition structure

       SYNOPSIS
             #include <sys/sdi.h>
             #include <sys/ddi.h>

       DESCRIPTION
             The sdi_edt is an internal SDI structure that defines an entry
             to the Equipped Device Table (EDT) and describes a PDI device
             or controller.  The scsi_adr represents the SCSI address of
             the device.  The curdev field identifies the target driver
             that currently owns the device.  The device type returned from
             the SCSI inquiry command is saved in devtype, and the inquiry
             string is saved in the inquiry field.  The memaddr and
             ctlorder fields are meaningful for EDT entries that describe
             the controller.  The memaddr is the ROM BIOS address used by
             the controller.  The ctlorder specifies the boot order of the
             controller, and is set if the HBA specified boot order in the
             hba_idata.  The edt_ident is the inquiry data structure
             returned by the device from the inquiry command.

          Return Values
             None.

       USAGE
             When sdi_register is called, SDI allocates an sdi_edt
             structure for each SCSI device found during inquiries to the
             controller.  The EDT entries represent all PDI devices that
             are configured in the system.  The pdiconfig(1M) command uses
             the contents of the EDT to configure the system for kernel
             configuration, and the pdimkdev(1M) command uses the contents
             of the EDT to make the PDI device nodes.

          Structure Members
             The sdi_edt structure is defined as follows:

             struct sdi_edt {
                 struct sdi_edt  *hash_p;    /* next sdi_edt in hash list */
                 short           hba_no;     /* HBA/path id */
                 unsigned char   scsi_id;    /* SCSI id */
                 unsigned char   lun;        /* logical unit number */
                 struct owner    *curdrv;    /* pointer to current owner */
                 struct owner    *owner_list;/* chain of owners of this edt */
                 unsigned long   res1;       /* reserved */
                 int             pdtype;     /* SCSI physical device type */
