NAME

       tk_scsiformat - low level format an scsi disk device with a nice user interface

SYNOPSIS

       tk_scsiformat [device]

DESCRIPTION

       Low  level formats the SCSI device identified by the scsi disk or generic scsi device node device.  You must be root to perform this opera-
       tion. When you do not specify a device, tk_scsiformat gives you a list to select a disk device from.

       tk_scsiformat is a Tcl/Tk user interface to scsiformat(8).

       You should read that manual page for the general operation of scsiformat.  All common X11 and Tcl/Tk options apply.

       By the nature of graphical user interfaces, there should not be much to explain here. All entry	fields	refer  directly  to  scsiformat(8)
       options.

       In  addition  to those, you are able to save your selections to be used as defaults for this device next time in a file /usr/lib/scsi/scsi-
       format.defs.*  by pressing the <Save Defaults> button. This is intended and very handy for formatting of removable medias.  Note,  however,
       that  tk_scsiformat is not as clever as scsiformat(8) (or even tries to be) to find if multiple ways to refer to the same scsi device (disk
       device, generic device).

       Furthermore, you can select (or enter freely) a command to automatically make a file system on the newly formatted disk.

       While formatting a nice completion bar is drawn. Alas, I could not really implement querying progress from a target device yet.

       The /usr/lib/scsi/tworands binary is used to calculate two random integers which is not supported by plain Tcl/Tk.

BUGS

       When not specifying a device to format, tk_scsiformat will prepare a list of disk devices to choose from. Alas, if a blocking format opera-
       tion is running on one of them, tk_scsiformat will block in a non interruptible disk wait sleep.

       Old status files in /tmp will confuse tk_scsiformat.  However, they are removed after 48 hours.

       Restrictions  of the SCSI_IOCTL_SEND_COMMAND ioctl(2) call for the sd(4) device make it impossible to issue a FORMAT_UNIT command with more
       than 4096 bytes of arguments. This could be avoided by using the proper generic scsi device /dev/sg* instead, at least where the kernel	is
       compiled to support it. Most of the time this is not needed though and thus I'm myself to lazy to do it.

NAME

       scsi-spin - spin up and down a SCSI device

SYNOPSIS

       scsi-spin [-options...] [device]

DESCRIPTION

       scsi-spin let the user to manually spin up and down a SCSI device.

       This  command is particularly useful if you've got noisy (or hot) drives in a machine that you rarely need to access.  This is not the same
       as the kernel patch that's floating around that will automatically spin down the drive after some time.	scsi-spin  is  completely  manual,
       and spinning down a drive that's in use, especially the one containing the scsi-spin binary, is probably a really bad idea.

       To  avoid running in trouble with such cases, scsi-spin verifies that the device to work on is not currently in use by scanning the mounted
       file system description file for a partition living on it and issue an error if this the case.

OPTIONS

       -u, --up
	      spin up device.

       -d, --down
	      spin down device.

       -e, --loej
	      load or eject medium from drive (use along with -u or -d )

       -w, --wait=[n]
	      wait up to n seconds for the spin up/down command to complete. Default is to return immediately after the command was  sent  to  the
	      device.  Either repeat -w n times or set n to define the time to wait before to report a timeout.

       -l, --lock
	      prevent removal of medium from device.

       -L, --unlock
	      allow removal of medium from device.

       -I, --oldioctl
	      use  legacy  ioctl  interface  instead  of SG_IO to dialog with device (could not be supported on all platforms).  -e and -w are not
	      allowed with this option.

       -v, --verbose=[n]
	      verbose mode. Either repeat -v or set n accordingly to increase verbosity. 1 is verbose, 2 is debug (dump SCSI  commands	and  Sense
	      buffer).

       -f, --force
	      force spinning up/down the device even if it is in use.

       -n, --noact
	      do nothing but check if the device is in use.

       -p, --proc
	      use /proc/mounts instead of /etc/mtab to determine if the device is in use or not.

       device the  device  is  any  name  in the filesystem which points to a SCSI block device (sd, scd) or generic SCSI device (sg). See section
	      below.

SCSI devices naming convention
   Old kernel naming convention
       It is typically /dev/sd[a-z] , /dev/scd[0-9]* or /dev/sg[0-9]*.

   scsidev naming convention
       It is typically /dev/scsi/s[rdg]h[0-9]*-e????c?i?l?  or /dev/scsi/<aliasname>.

   devfs naming convention
       It  is  typically  /dev/scsi/host[0-9]/bus[0-9]/target[0-9]/lun[0-9]/disc   (same   for	 cd   and   generic   devices)	 or   short   name
       /dev/sd/c[0-9]b[0-9]t[0-9]u[0-9] when devfsd "new compatibility entries" naming scheme is enabled.
