Configure Storage Server with iSCSI.
A storage on a network is called iSCSI Target, a Client which connects to iSCSI Target is called iSCSI Initiator.
This example is based on the environment below. +----------------------+ | +----------------------+ | [ iSCSI Target ] |10.0.0.30 | 10.0.0.31| [ iSCSI Initiator ] | | dlp.srv.world +----------+----------+ client.srv.world | | | | | +----------------------+ +----------------------+ |
| [1] | Install administration tools. |
|
root@dlp:~# apt-get -y install iscsitarget iscsitarget-dkms
|
| [2] | Configure iSCSI Target . For example, create a disk image under the [/iscsi_disks] directory and set it as a shared disk. |
|
# create a disk image root@dlp:~# mkdir /iscsi_disks root@dlp:~# dd if=/dev/zero of=/iscsi_disks/disk01.img count=0 bs=1 seek=80G
root@dlp:~#
vi /etc/default/iscsitarget # change ISCSITARGET_ENABLE= true
root@dlp:~#
vi /etc/iet/ietd.conf # add follows to the end # if you set some devices, add <target>***</target> and set the same way with follows # naming rule : [ iqn.yaer-month.domain:any name ] Target iqn.2015-05.world.srv:target00 # provided devicce as a iSCSI target Lun 0 Path=/iscsi_disks/disk01.img,Type=fileio # iSCSI Initiator's IP address you allow to connect initiator-address 10.0.0.31 # authentication info ( set anyone you like for "username", "password" ) incominguser username password
root@dlp:~#
