iSCSI Network storage configuration under Linux

The main functionality of ISCSI is the encapsulation and reliable transmission of large amounts of data between host systems (initiator initiator) and storage devices (target targets) on TCP/IP networks. You need to install target on the server of Linux, and the client will install Inititor.

The configuration process is as follows:

Test IP as 192.168.157.144 on the host

[email protected] ~]# Yum install iscsi-initiator-utils.i386

[email protected] ~]# Yum install scsi-target-utils.i386

Start target when installation is complete

Target's configuration file is only/etc/tgt/targets.conf

in the SRV under iSCSI directory to build an IMG file to use as iSCSI Network file sharing
