1 Introduction

Technology is beautiful, isn’t it! Here’s a guide to create an iSCSI share between Solaris and Debian. Be careful with performance as this remains iSCSI - I don’t recommend it for production environments unless you know what you’re doing.

In this setup, Solaris will be our server and Debian our client.

2 Installation

2.1 Solaris

Let’s verify that we have the required packages:

  $ pkginfo | grep iscsi
system      SUNWiscsir                       Sun iSCSI Device Driver (root)
system      SUNWiscsitgtr                    Sun iSCSI Target (Root)
system      SUNWiscsitgtu                    Sun iSCSI Target (Usr)
system      SUNWiscsiu                       Sun iSCSI Management Utilities (usr)

2.2 Debian

Let’s install Open iSCSI:

  apt-get install open-iscsi

3 Configuration

3.1 Solaris

Activate the iSCSI target service:

  svcadm enable iscsitgt

Now, let’s configure iSCSI discovery:

  iscsiadm modify discovery –sendtargets enable
iscsiadm add discovery-address <ip_solaris>

Create ZFS volumes to export:

  zfs create tank/xen
zfs set shareiscsi=on tank/xen

Volume1 will inherit properties from tank/xen and will be shared automatically:

  zfs create -s -V 10g tank/xen/volume1

Then verify that everything is working:

  iscsiadm list target
Target: iqn.1986-03.com.sun:02:6bc5ce3d-eb83-4055-fe67-d1fd9a7eb7b7
        Alias: tank/xen/volume1
        TPGT: 1
        ISID: 4000002a0000
        Connections: 1

3.2 Debian

Log into the target:

  iscsiadm -m discovery -t st -p <ip_solaris>
<ip_solaris>:3260,1 iqn.1986-03.com.sun:02:6bc5ce3d-eb83-4055-fe67-d1fd9a7eb7b7
debian-test# iscsiadm  -m node -l -T "iqn.1986-03.com.sun:02:6bc5ce3d-eb83-4055-fe67-d1fd9a7eb7b7?
