iscsidinterface to kernel iSCSI driver


iscsid [-n] [-d lvl]


The iSCSI initiator runs as a kernel driver, and provides access to iSCSI targets running across a network using the iSCSI protocol, RFC 3270. The iscsid utility itself interfaces to the kernel iSCSI driver, and also communicates, using isns(3), with the iSCSI name service running on other hosts to locate services and iSCSI instances. In normal operation, iscsid is a standard daemon, and will detach from the controlling terminal using daemon(3) and then loops, reading requests, processing them, and sending responses. Communication takes place over a Unix domain socket. iscsid exits on receiving a terminate message, (no response to one that is sent to the kernel), or when an error occurs reading from or writing to the socket.

The -d flag increases the debug level to lvl. Any level above 0 causes iscsid to remain in the foreground, and increases the amount of debug output. The -n flag makes the daemon single-threaded.

It is envisaged that user-level communication take place with iscsid using the iscsictl(8) utility, rather than directly over its communication socket. An example of setting up the in-kernel iSCSI initiator is shown in iscsictl(8).

iscsid requires scsibus(4) and sd(4) compiled in the kernel to load the iscsi kernel module.


The iscsid utility appeared in NetBSD 6.0.
