Introduction-------------iSCSI Enterprise Target is for building an iSCSI storage system onLinux. It is aimed at developing an iSCSI target satisfying enterpriserequirements.We borrow code from an Ardis iSCSI target (with respect to the GPL).Installation-------------The iSCSI target requires a host running the Linux operating systemwith a kernel version of 2.6.13 or newer. You need to enable "Cryptographic API" under "Cryptographic options" in the kernel config. You also need to enable "CRC32c CRC algorithm" if you use header or data digests. They are the kernel options, CONFIG_CRYPTO and CONFIG_CRYPTO_CRC32C,respectively.The iSCSI target consists of kernel modules and a daemon. Thecompilation of the kernel modules require the path to above kernelsources:	make KERNELSRC=<kernel-src>The path can also be set by editing the main Makefile. If KERNELSRC is omitted,make program will try to locate the kernel sources for current running kernel.Be sure to check whether it finds the right kernel sources.This will build the modules, the daemon, and the control tool. To install both, use:	make KERNELSRC=<kernel-src> installThe kernel modules will be install in the module directory of thekernel. The daemon and the control tool will be installed as ietd andietadm under /usr/sbin. The boot script will be installed asiscsi-targt under /etc/init.d.If you use Linux distribution that does not have /etc/init.d, theboot script will not be installed. So you need to install it to anappropriate directory manually.Configuration-------------The daemon is configured via the configuration file /etc/ietd.conf.See the man page and the example file for the current syntax.The ietadm utility is for managing IET software dynamically. You canchange the configurations of running targets. See the help message.The access control based on initiator address and target name patternsis configured via two configuration files (/etc/initiators.allow and/etc/initiators.deny). These files work like tcpd files(/etc/hosts.allow and /etc/hosts.deny). This feature enables you tohide a particular targets from some initiators. See the example filesfor the supported expressions. You can change the configurationdynamically. The modifications to the files become effectiveimmediately.Starting-------------The target is not started automatically. So execute:	/etc/init.d/iscsi-target startNote that you must edit the configuration file before starting thetarget.Stopping-------------Execute:	/etc/init.d/iscsi-target stop
