iSCSI Configuration Full Raiders (iSCSI Target/initiator)

1.Target-side configuration

The target side is the disk array or other host with disk. The Iscsitarget tool maps disk space to the network, and the initiator side can find and use the disk.

Note that a target host can map multiple target to a network, that is, multiple block devices can be mapped to the network.

1) package

You can download the latest version from http://sourceforge.net/projects/iscsitarget/files/.

2) Compile and install

/etc/initiators.allow controls initiator access to target.

/etc/initiators.deny controls initiator access to target.

/etc/iet/targets.allow controls the access rights of different target.

3) Configure/etc/ietd.conf

Target iqn.2001-04.com.example:storage.disk2.sys1.xyz

Lun 0 Path=/dev/sda1,type=fileio

Alias Lun0

General Description:

Target IQN.2001-04.COM.EXAMPLE:STORAGE.DISK2.SYS1.XYZ represents the name of the iSCSI Target, which should be unique within the same subnet, and the standard naming method is:

"Target" + Target name (format: iqn.yyyy-mm.<reversed domain Name>[:identifier])

Lun 0 PATH=/DEV/SDA1 indicates that the block device number is 0 and the mapped disk is/dev/sda1.

The Type in this configuration is set to "FileIO", and I am primarily used to store and share a disk.

It can also be set to: "File" or "LVM", as needed.

In addition, there are many other parameters can be set, specific reference:
