ISCSI - Server and Client Side

iSCSI is an Internet Protocol (IP)-based storage networking standard for linking data storage facilities. By carrying SCSI commands over IP networks, iSCSI is used to facilitate data transfers over intranets and to manage storage over long distances. iSCSI can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet, and can enable location-independent data storage and retrieval.

Steps

1) Create LVM with name iscsi

2) Install package scsi-target-utils

vim /etc/tgt/target.conf

<target iqn.yyyy.mm.revers order name>

e.g.

<target iqn,2010-12.com.example.desktop4:iscsi>

backing-store /dev/vol1/iscsi

initiator-address 192.168.0.5  

initiator-address 192.168.0.6

initiator-address 192.168.0.7

<target>

3) Service tgtd restart

4) Chkconfig tgtd on

5) Tgtd-admin –s

This will create an iSCSI server; Check iSCSI Client side below

1) Yum install iscsi-initiator*

2) iscsiadm –m discovery –t st –p [IP of iscsi server]

3) isciadmin –m node –T iqn.string -l -> For Login the iscsi

4) Check for new HDD in using fdisk -l and do partition using Fdisk.
