Usage: sg_start [--eject] [--fl=FL] [--help] [--immed] [--load] [--loej]
[--mod=PC_MOD] [--noflush] [--pc=PC] [--readonly]
[--start] [--stop] [--verbose] [--version] DEVICE
where:
--eject|-e stop unit then eject the medium
--fl=FL|-f FL format layer number (mmc5)
--help|-h print usage message then exit
--immed|-i device should return control after receiving cdb,
default action is to wait until action is complete
--load|-l load medium then start the unit
--loej|-L load or eject, corresponds to LOEJ bit in cdb;
load when START bit also set, else eject
--mod=PC_MOD|-m PC_MOD power condition modifier (def: 0) (sbc)
--noflush|-n no flush prior to operation that limits access (sbc)
--pc=PC|-p PC power condition: 0 (default) -> no power condition,
1 -> active, 2 -> idle, 3 -> standby, 5 -> sleep (mmc)
--readonly|-r open DEVICE read-only (def: read-write)
recommended if DEVICE is ATA disk
--start|-s start unit, corresponds to START bit in cdb,
default (START=1) if no other options given
--stop|-S stop unit (e.g. spin down disk)
--verbose|-v increase verbosity
--old|-O use old interface (use as first option)
--version|-V print version string then exit
Example: 'sg_start --stop /dev/sdb' stops unit
'sg_start --eject /dev/scd0' stops unit and ejects medium
Performs a SCSI START STOP UNIT command
Options (17)
| Option | Description | Source |
|---|
--fl, -f FL|-f | sets the format layer number for the disc to "jump" to (defined in MMC-5). | help + man |
--mod, -m PC_MOD|-m | where PC_MOD is the 'power condition modifier' value. | help + man |
--pc, -p PC|-p | power condition: 0 (default) -> no power condition, 1 -> active, 2 -> idle, 3 -> standby, 5 -> sleep (mmc) | help + man |
-e, --eject | stop the medium and eject it from the drive. (in the manual page but not in --help) | man |
-h, --help | print out the usage message then exit. (in the manual page but not in --help) | man |
-i, --immed | sets the IMM bit on the START STOP UNIT command so this utility will return immediately and not wait for the media to complete the requested action. (in the manual page but not in --help) | man |
-l, --load | load the medium in the drive and start it. (in the manual page but not in --help) | man |
-L, --loej | sets the LOEJ bit on the START STOP UNIT command. (in the manual page but not in --help) | man |
-n, --noflush | do not perform a flush to media (e.g. like SYNCHRONIZE CACHE does) before a variant of this utility that limits access to the media. (in the manual page but not in --help) | man |
-O, --old | Switch to older style options. (in the manual page but not in --help) | man |
-r, --readonly | open the DEVICE in read-only mode. (in the manual page but not in --help) | man |
-s, --start | start (spin-up) the DEVICE. (in the manual page but not in --help) | man |
-S, --stop | stop (spin-down) the DEVICE. (in the manual page but not in --help) | man |
-v, --verbose | increase the level of verbosity. (in the manual page but not in --help) | man |
-V, --version | print out version string then exit. (in the manual page but not in --help) | man |
--imm 0|1 | when the immediate bit is 1 then this utility returns immediately after the DEVICE has received the command. (in the manual page but not in --help) | man |
-N, --new | Switch to the newer style options. (in the manual page but not in --help) | man |
