scsi_cname, scsi_dname, scsi_mname, scsi_rname, scsi_sname - decode a SCSI name

char *scsi_cname(uchar_t cmd, char **cmdvec);

char *scsi_dname(int dtype);

char *scsi_rname(uchar_t reason);

char *scsi_sname(uchar_t sense_key);

illumos DDI specific (illumos DDI). cmd cmdvec dtype msg reason sense_key The scsi_cname() function decodes SCSI commands. cmdvec is a pointer to an array of strings. The first byte of the string is the command value, and the remainder is the name of the command.

The scsi_dname() function decodes the peripheral device type (for example, direct access or sequential access) in the inquiry data.

The scsi_mname() function decodes SCSI messages.

The scsi_rname() function decodes packet completion reasons.

The scsi_sname() function decodes SCSI sense keys.

These functions return a pointer to a string. If an argument is invalid, they return a string to that effect. These functions can be called from user, interrupt, or kernel context. Example 1 Decoding SCSI tape commands.

The scsi_cname() function decodes SCSI tape commands as follows:

static char *st_cmds[] = {
 "\e000test unit ready",
 "\e001rewind",
 "\e003request sense",
 "\e010read",
 "\e012write",
 "\e020write file mark",
 "\e021space",
 "\e022inquiry",
 "\e025mode select",
 "\e031erase tape",
 "\e032mode sense",
 "\e033load tape",
 NULL
 };
 ..
 cmn_err(CE_CONT, "st: cmd=%s", scsi_cname(cmd, st_cmds));
