NAME
tgtd - The SCSI Target Daemon SYNOPSIS
tgtd tgtd [-C --control-port <INTEGER>] [-d --debug <INTEGER>] [-f --foregound] [-h --help] [--iscsi <...>] DESCRIPTION
Tgtd is a SCSI Target daemon. It can be used to provide SCSI target service to a network. The most common service is iSCSI but other services are also supported. DEVICE TYPES
Tgtd provides support for both emulated and passthrough of real devices. Tgtd can emulate the following types of devices: disk : Normal disk device. Emulates a SCSI harddisk. tape : Tape device. Emulates a SCSI tape drive. cd : CD device. Emulates a SCSI DVD burner. changer : Media changer. Emulate the changer device for a virtual tape library or DVD jukebox. OPTIONS
-d --debug <INTEGER> Set to non-zero value to activate additional debugging messages to be logged. -f --foreground Run the daemon in the foreground. -h --help Print help text to the screen. -C --control-port <INTEGER> This comamnd is used to specify the control port to use for this instance of tgtd. This allows to run multiple instances of TGTD on a host. TGTADM has a matching argument to control which instance to connect to. --iscsi <...> ISCSI specific options. See the ISCSI section below for options specific to this frontend. ISCSI OPTIONS
These parameters apply only to the iSCSI frontend. portal=<ip-address[:port]> This option is used to bind tgtd to a specific ip-address/portal and/or port. By default tgtd will bind to port 3260 on the wildcard address. The ip-address part (before the ":") can be missing to designate the wildcard address with a none-default port. Example: to bind tgtd to a specific address and port tgtd --iscsi portal=192.0.2.1:3260 Example: to bind tgtd to any address but a none-default port tgtd --iscsi portal=:3251 SEE ALSO
