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.
