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.
