sg_prevent
SG_PREVENT(8) SG3_UTILS SG_PREVENT(8)NAME
sg_prevent - send SCSI PREVENT ALLOW MEDIUM REMOVAL command
SYNOPSIS
sg_prevent [--allow] [--help] [--prevent=PC] [--verbose] [--version] DEVICE
DESCRIPTION
Sends a SCSI PREVENT ALLOW MEDIUM REMOVAL command to DEVICE. The default action of this utility is to prevent the removing or ejecting of
the medium from a drive. This is done by ignoring the SCSI START STOP UNIT command (see sg_start) and ignoring the eject button on the
drive when the user presses it. Drives that hold removable disks, tape cartridges or cd/dvd media typically implement this command. The
definition of the "prevent" codes for this command differ between disks and tapes (covered by SBC-3 and SSC-3) and cd/dvd drives (covered
by MMC-5). The "prevent codes" described here are from MMC-5.
OPTIONS
Arguments to long options are mandatory for short options as well.
-a, --allow
allow medium removal. This is equivalent to setting to '--prevent=2'. Cannot be used with --prevent=PC option (i.e. either use no
options (hence prevent removal), this option or --prevent=PC).
-h, --help
output the usage message then exit.
-p, --prevent=PC
where PC is a prevent code value. Defined values are: 0 allows removal, 1 prevents removal (default), 2 allows persistent removal
while 3 prevents persistent removal. "Persistent" in this context means that the initiator (port) that successfully uses code 3
blocks other initiators (ports) from allowing removal. A "persistent prevent" state can be cleared by the owner allowing persistent
removal (code 2) or a power cycle (or anything that resets the device (LU)) or some special commands (e.g. various service actions
of Persistent Reserve Out, see SPC-3).
-v, --verbose
increase the level of verbosity, (i.e. debug output).
-V, --version
print the version string and then exit.
EXIT STATUS
The exit status of sg_prevent is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
