-- Initiator-address abbreviation -- I

Targetname:

Iqn. yyyy-Mm. <reversed. Domain Name> [: identifier]

Example: iqn.2014-10.com. zzc. Nokia: Test

Create target: tgtadm -- LLD iSCSI -- Mode target -- op new -- targetname iqn.2014-10.com. zzc. Nokia: Test -- TID 1

View: tgtadm -- LLD iSCSI -- Mode target -- op show

Create logicalunit: tgtadm -- LLD iSCSI -- Mode logicalunit -- op new -- TID 1 -- Lun 1 -- backing-store/dev/SDB

Create IP-based authentication: tgtadm -- LLD iscis -- Mode target -- op bind -- TID 1 -- initiator-Address 192.168.1.0/24

Client configuration: 1. Install iSCSI-initiator-utils Yum-y install iSCSI-initiator-utils.

Start Service: Service iSCSI start

Discovery: find out whether a service has target output and what target is output

Node: manages the association between a target and a root target.

Session: session management

Iface: Interface Management

For example, the target: iscsiadm-M discovery-D 2-T St-P 192.168.1.100

Log on to a target iscis-M node-T iqn.2014-10.com. zzc. Nokia: Test-P 192.168.1.100-l
