       scsi-spin - spin up and down a SCSI device

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

       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.

       -u, --up
              spin up device.

       -d, --down
              spin down device.

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

       -f, --force
              force spinning up/down the device even if it 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

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

   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.
