35 .Nd CAM Target Layer / iSCSI target daemon
39 .Op Fl f Ar config-file
44 daemon is responsible for managing the CAM Target Layer configuration,
45 accepting incoming iSCSI connections, performing authentication and
46 passing connections to the kernel part of the native iSCSI target.
50 daemon parses the configuration file.
51 If it encounters any errors,
54 It then compares the configuration with the kernel list of LUNs managed
57 instances, removes LUNs no longer existing in the configuration file,
58 and creates new LUNs as necessary.
59 After that it listens for the incoming iSCSI connections, performs
60 authentication, and, if successful, passes the connections to the kernel part
63 which handles it from that point.
65 When it receives a SIGHUP signal, the
67 reloads its configuration and applies the changes to the kernel.
68 Changes are applied in a way that avoids unnecessary disruptions;
69 for example removing one LUN does not affect other LUNs.
71 When exiting gracefully, the
73 daemon removes LUNs it managed and forcibly disconnects all the clients.
74 Otherwise - for example, when killed with SIGKILL - LUNs stay configured
75 and clients remain connected.
77 To perform administrative actions that apply to already connected
78 sessions, such as forcing termination, use
81 The following options are available:
82 .Bl -tag -width ".Fl P Ar pidfile"
83 .It Fl f Ar config-file
84 Specifies the name of the configuration file.
89 The daemon sends verbose debug output to standard error, and does not
90 put itself in the background.
91 The daemon will also not fork and will exit after processing one connection.
92 This option is only intended for debugging the target.
94 Use UCL configuration file format instead of the traditional non-UCL format.
