scsi_start
SCSI_START(8) SG3_UTILS SCSI_START(8)
NAME
scsi_start - start one or more SCSI disks
SYNOPSIS
scsi_start [--help] [--verbose] [--wait] DEVICE [DEVICE]*
DESCRIPTION
This bash shell script calls the sg_start utility on each given DEVICE. The purpose is to spin up (start) each given DEVICE.
OPTIONS
Arguments to long options are mandatory for short options as well.
-h, --help
print out the usage message then exit.
-v, --verbose
increase level or verbosity.
-w, --wait
wait for the spin up (start) on each given DEVICE to complete. The default action is to do each start in immediate mode.
NOTES
If a large number of disks are spun up at the same time (i.e. without the --wait option) then the power supply may be overloaded.
EXIT STATUS
The exit status of this script is 0 when it is successful. Otherwise the exit status is that of the last sg_start utility called. See the
sg3_utils(8) man page.
