NAME


istgtcontrol - istgt iSCSI target command utility

SYNOPSIS


istgtcontrol [options] <command> [<file>]

DESCRIPTION


istgtcontrol is a command and control utility for istgt(1). It can be used to query and
change the status of a local or remote istgt instance.

istgtcontrol supports the commands denoted below to interact with the istgt instance. By
default it connects and authenticates to the iSCSI target portal specified in the
istgtcontrol.conf configuration file and uses CHAP credentials denoted there, if any.
Both can be overridden by using the respecitve command line arguments.

COMMANDS


istgtcontrol understands the following commands which can be forwarded to istgt:

noop Do not actually do anything, but test responsiveness of the portal and test CHAP
credentials only.

version
Retrieve the istgt version number providing the iSCSI portal istgtcontrol connected
to.

list List all, or the specified targets only, which shared by the portal.

load Load a new media to the specified unit. This command issues the same command as if
a drive tray had been closed on a SCSI device.

unload Unload a media from the specified unit. This command issues the same command as if
the drive tray had been opened from a SCSI device.

change file
Change the loaded media by the specified unit. This command is equivalent as if a
new media (for example a DVD-ROM or tape cartridge) had been inserted in the SCSI
drive. The "file" argument is interpreted as filename to be loaded.

reset Reset the specified LUN of the portal.

info Display all connections of the portal

OPTIONS

-h host
Override the target portal by the specified host name or IP address. This defaults
to "localhost" if no other host was specified in the configuration file.

"3261" if no other port was specified in the configuration file.

Specifies the target IQN which should be affected by the command given. There may
be a default given in the configuration file. The keyword "all" is accepted by some

media size.
