How to set up iSCSI virtualization

Hi,

I was starting to configure virtual iSCSI. But there is one problem. Please see my configuration steps:

- -

Reqirement

* iSCSI Target Machine (server side)

HW: Sparc

OS: Solaris 11

* iSCSI Initiator Machine (client side)

HW: Sparc

OS: Solaris 10

1. Configure iSCSI Target

* Enable iSCSI Services

# svcadm enable iscsitgt

# svcs -a | grep iscsi

disabled 21:20:36 svc:/network/iscsi_initiator:default

online 21:49:29 svc:/system/iscsitgt:default |

* Create ZFS storage

# mkfile 2g /usr/tmp/iscsitest.2g

# zpool create test /usr/tmp/iscsitest.2g

# zpool list

NAME SIZE USED AVAIL CAP HEALTH ALTROOT

test 1.98G 88K 1.98G 0% ONLINE -

* Create ZFS Volume

# zfs create -V 1gb test/vol

# zfs list

NAME USED AVAIL REFER MOUNTPOINT

test 1.00G 976M 24.5K /test

test/vol 22.5K 1.95G 22.5K

* Assign ZFS as Virtual iSCSI HD

# iscsitadm modify admin -d /test

# iscsitadm show admin

iscsitadm:

Base Directory: /test

CHAP Name: Not set

RADIUS Access: Not set

RADIUS Server: Not set

iSNS Access: Not set

Fast Write ACK: Not set

# zfs set shareiscsi=on test/vol

* Make sure iSCSI Target has been created

# iscsitadm list target -v

Target: test/vol

iSCSI Name: iqn.1986-03.com.sun:02:882dc508-86d5-47be-a7cc-92c931245fea

2. Configure iSCSI Initiator

* Enable iSCSI Services

# svcadm enable iscsi_initiator

# svcs -a | grep iscsi

enable 21:20:36 svc:/network/iscsi_initiator:default

iscsiadm list initiator-node

Initiator node name: iqn.1986-03.com.sun:01:e0000000783b.45b5b9dc

Actually I couldn't find c4t01000014... drive on Target machine.

What is the problem?

Thanks,

Is there any one that could help me?

I have seen the following error message during the iSCSI configuration:

Thanks,
