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 Bourne 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. AUTHORS
