daemon is responsible for managing the CAM Target Layer configuration,
accepting incoming iSCSI connections, performing authentication and
passing connections to the kernel part of the native iSCSI target.
Upon startup, the
daemon parses the configuration file and exits, if it encounters any errors.
Then it compares the configuration with the kernel list of LUNs managed
by previously running
instances, removes LUNs no longer existing in the configuration file,
and creates new LUNs as necessary.
After that it listens for the incoming iSCSI connections, performs
authentication, and, if successful, passes the connections to the kernel part
of CTL iSCSI target, which handles it from that point.
When it receives a SIGHUP signal, the
reloads its configuration and applies the changes to the kernel.
Changes are applied in a way that avoids unnecessary disruptions;
for example removing one LUN does not affect other LUNs.
When exiting gracefully, the
daemon removes LUNs it managed and forcibly disconnects all the clients.
Otherwise - for example, when killed with SIGKILL - LUNs stay configured
and clients remain connected.
To perform administrative actions that apply to already connected
sessions, such as forcing termination, use
The following options are available:
Specifies the name of the configuration file.
The default is
The server sends verbose debug output to standard error, and does not
put itself in the background.
The server will also not fork and will exit after processing one connection.
This option is only intended for debugging the target.
