http://techsupportpk.blogspot.com/2013/09/iscsistorage.html

This short tutorial will guide you how to add iSCSI storage under Oracle Solaris 11 and how to create partition of iSCSI disk.

Check iSCSI discovery status

root@psrserver:~# iscsiadm list discovery
Discovery:
        Static: disabled
        Send Targets: disabled
        iSNS: disabled

Enable iSCSI Static discovery

root@psrserver:~# iscsiadm modify discovery -s enable

root@psrserver:~# iscsiadm list discovery
Discovery:
        Static: enabled
        Send Targets: disabled
        iSNS: disabled

Add iSCSI targets

root@psrserver:~# iscsiadm add static-config \ iqn.2006-01.com.openfiler:tsn.9b2243435347,172.22.2.15

root@psrserver:~# devfsadm -C -i iscsi
