hdio(4i)

Ioctls for a class of drivers or subsystems                           hdio(4I)



NAME
       hdio - SMD and IPI disk control operations

SYNOPSIS
       #include <sys/hdio.h>

DESCRIPTION
       Note -



         The  SMC  and IPI drivers have been discontinued. dkio(4I) is now the
         preferred method for retrieving disk information.



       The SMD and IPI disk drivers supplied with this release support  a  set
       of  ioctl(2) requests for diagnostics and bad sector information. Basic
       to these ioctl() requests are the definitions in <sys/hdio.h>.

IOCTLS
       HDKIOCGTYPE    The argument  is  a  pointer  to  a  hdk_type  structure
                      (described  below).  This ioctl() gets specific informa‐
                      tion from the hard disk.


       HDKIOCSTYPE    The argument  is  a  pointer  to  a  hdk_type  structure
                      (described  below).  This ioctl() sets specific informa‐
                      tion about the hard disk.


         /*
          * Used for drive info
          */
         struct hdk_type {
          ushort_t  hdkt_hsect;    /* hard sector count (read only) */
          ushort_t  hdkt_promrev;  /* prom revision (read only) */
          uchar_t   hdkt_drtype;   /* drive type (ctlr specific) */
          uchar_t   hdkt_drstat;   /* drive status (ctlr specific, ro) */
         };


       HDKIOCGBAD    The argument is  a  pointer  to  a  hdk_badmap  structure
                     (described  below).  This  ioctl() is used to get the bad
                     sector map from the disk.


       HDKIOCSBAD    The argument is  a  pointer  to  a  hdk_badmap  structure
                     (described  below).  This  ioctl() is used to set the bad
                     sector map on the disk.


         /*
          * Used for bad sector map
          */
         struct hdk_badmap {
              caddr_t   hdkb_bufaddr;  /* address of user's map buffer */
         };


       HDKIOCGDIAG    The argument  is  a  pointer  to  a  hdk_diag  structure
                      (described  below).  This  ioctl()  gets the most recent
                      command that failed along with the sector and error num‐
                      ber from the hard disk.


         /*
          * Used for disk diagnostics
          */
         struct hdk_diag {
          ushort_t hdkd_errcmd;  /* most recent command in error */
          daddr_t  hdkd_errsect; /* most recent sector in error */
          uchar_t  hdkd_errno;   /* most recent error number */
          uchar_t  hdkd_severe;  /* severity of most recent error */
         };
