NAME
       scsimodes -  Determine the geometry and capacity of a SCSI disk drive

SYNOPSIS
       usretcscsimodes [ -C ] [-v] raw_disk_device

DESCRIPTION
       scsimodes  queries  the disk to determine its capacity and geometry. If
       you have trouble creating a filesystem on the disk, use this command to
       help you diagnose the problem.  With no command line options, scsimodes
       prints to standard output the drive's manufacturer and model,  and  the
       number of bytes per sector, sectors per track, tracks per cylinder, and
       other information relevant to formatting the disk.

       At the SCSI command level, scsimodes executes a READ CAPACITY  command,
       and  two	 MODE SENSE commands, one for page 3 (format device page), and
       one for page 4 (rigid disk geometry page) of the mode sense parameters.

OPTIONS
       -C     Report the storage capacity of the disk, in megabytes.

       -v     (Verbose mode)  Report detailed  information  about  the	disk's
	      geometry.	    It	is  unlikely  that you will need this level of
	      detail.

EXAMPLES
       To see the basic formatting information	for  your  root	 disk  device,
       become superuser and type:

       scsimodes /dev/rsd0a

       To determine how many megabytes of data this disk can store, type:

       scsimodes -C /dev/rsd0a

SEE ALSO
       sd(4), disktab(5), disk(8), mkfs(8)

DIAGNOSTICS
       scsimodes exits with status 0 after successful execution.  If it fails,
       it prints a diagnostic message, and exits with status 1.
