Overview

This article will guide the administrator into mounting an iSCSI Target from the Synology DiskStation onto a Linux computer. Please make sure that an iSCSI Target has been created on the DiskStation and is ready for use. This article was created with a Fedora 13, and a Synology DiskStation DS508 with DSM 3.0-1354. Please consult with the Linux Distribution website for more specific instructions for each specific version of Linux.

Adding iSCSI Storage to a Linux Computer

Step 1: Install the iSCSI Initiator Software [root@Synology-FedoraVM /]# yum install iscsi-initiator-utils Loaded plugins: presto, refresh-packagekit Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package iscsi-initiator-utils.i686 0:6.2.0.872-7.fc13 set to be installed --> Finished Dependency Resolution ... Installed: iscsi-initiator-utils.i686 0:6.2.0.872-7.fc13 Complete!

Step 2: Make sure iscsi.conf 'node' parameter is set for Automatic [root@Synology-FedoraVM /]# vi /etc/iscsi/iscsid.conf [...] node.startup = automatic [...]

Step 3: Start Discovery Process [root@Synology-FedoraVM /]# iscsiadm -m discovery -t st -p 192.168.0.227 Starting iscsid: [ OK ] 192.168.0.227:3260,0 iqn.2010-10.synology-iscsi:newvirtualdisk.1 169.254.1.2:3260,0 iqn.2010-10.synology-iscsi:newvirtualdisk.1 [root@Synology-FedoraVM /]# iscsiadm -m node 169.254.1.2:3260,0 iqn.2010-10.synology-iscsi:newvirtualdisk.1 192.168.0.227:3260,0 iqn.2010-10.synology-iscsi:newvirtualdisk.1

Step 4: Log onto a iSCSI Target [root@Synology-FedoraVM /]# iscsiadm -m node --targetname "iqn.2010-10.synology- iscsi:newvirtualdisk.1" --portal "192.168.0.227:3260" --login Logging in to [iface: default, target: iqn.2010-10.synology-iscsi:newvirtualdis k.1, portal: 192.168.0.227,3260] Login to [iface: default, target: iqn.2010-10.synology-iscsi:newvirtualdisk.1, portal: 192.168.0.227,3260] successful.
