scsi_start man page

scsi_start — start one or more SCSI disks


scsi_start [--help] [--verbose] [--wait] DEVICE [DEVICE]*


This bash shell script calls the sg_start utility on each given DEVICE. The purpose is to spin up (start) each given DEVICE.


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.


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.
