This article explains about adding the ISCSI target on Solaris node.Once you installed the openfiler,you have to provision LUN to specific target in order to access LUNS in operating system.Once its done,then we just need to add those targets in OS to see those disks.Here we will see, how to add the iscsi target in Solaris in details manner.

Assumption:Here i have already provision lun1 & lun2 to specific target iqn.2006-01.com.openfiler:tsn.58533bc21b9e.

bash-3.00# svcadm enable iscsitgt
bash-3.00# svcs -a |grep iscsitgt
online 22:47:20 svc:/system/iscsitgt:default

Add the static target using the above mentioned target number.

# iscsiadm add static-config iqn.2006-01.com.openfiler:tsn.58533bc21b9e
,192.168.2.7:3260

Note:openfiler and Solaris host should be in same network in order to access the shared storage.
Openfiler IP:192.168.2.7 Default port:3260
Target:iqn.2006-01.com.openfiler:tsn.58533bc21b9e

Verify the target number

># iscsiadm list static-config
Static Configuration Target: iqn.2006-01.com.openfiler:tsn.58533bc21b9e,192.168.2.7:3260

Enable the discovery:

# iscsiadm modify discovery -s enable

Scan the LUN in OS side.

# devfsadm -i iscsi -v

# echo |format

Now your shared storage setup is ready.You can add multiple target for same LUNS and that will act as alternative path for those LUNS.So that we can practice multi-pathing as well.
