NAME

hdio - SMD and IPI disk control operations
 

SYNOPSIS

#include <sys/hdio.h> 

DESCRIPTION

Note -

The SMC and IPI drivers have been discontinued. dkio(7I) 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 information from the hard disk.

HDKIOCSTYPE

The argument is a pointer to a hdk_type structure (described below). This ioctl() sets specific information 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 number 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 */
};
