After a successful clone of my OS-disk in 75 minutes with CloneZilla I tried to do the same with Ghost 4 Linux (G4L). I used the latest version 0.30 and used similar option to clone the disk/partition: source hdb1 -> sda1. Sda1 was again attached via USB using my usb/IDE adapter.
G4L managed to clone the disk in less than 15 minutes for 20GB. So almost 4 times faster than CloneZilla.
Booting with the new cloned disk did not give any problems.

Import existing array to new server
After a POC (Proof of Concept) with openSolaris on an old Dell GX270 with a zfs pool "daw" I wanted to know how to link that existing pool to my new Config based on M4N78-PRO setup:
admin@dawbckup:~# zpool import daw
cannot import 'daw': pool may be in use from other system, it was last accessed by dawbkup (hostid: 0xc9e4de) on Wed May 6 16:02:36 2009
use '-f' to import anyway
admin@dawbckup:~# zpool import -f daw
cannot share 'daw/backup': iscsitgtd failed request to share
zfs set shareiscsi=on daw/backup
admin@dawbckup:/etc# iscsitadm list target -v
Target: daw/backup
iSCSI Name: iqn.1986-03.com.sun:02:aa46a269-bef7-4432-9ed2-9890738fc784
Alias: daw/backup
Connections: 0
---
Voila here it is back again. Now I can mount it again in windows and we're back in business.

Clonezilla to make Backup OpenSolaris Bootdisk
I wanted to check if it was possible to clone my bootdisk with Opensolaris.
I used the latest version: clonezilla-live-1.2.2-14.iso
Booted with the clonezilla CD and chose the option "device to device clone"
My OpenSolaris bootdisk partition was recognized as hdb1.
I connected the new disk using my IDE to USB adapter and this disk was called sda1
Clonezilla asked If I wanted to replace the bootsector on the target (=yes)
After giving the final approval it went off and my 20GB partition took about 75 minutes.
Replacing the original bootdisk in the server with this cloned copy booted up fine!
Hurray for Clonezilla

Add ISCSI package
After the update to the latest version:
admin@dawbckup:/etc# uname -a
SunOS dawbckup 5.11 snv_111a i86pc i386 i86pc
You have to select from the Category "Storage" the package "storage-nas"
Without it I could not run the command: iscsitadm list target -v
admin@dawbckup:/etc# uname -a
SunOS dawbckup 5.11 snv_111a i86pc i386 i86pc

Without it I could not run the command: iscsitadm list target -v
update to the latest OpenSolaris (save Boot Environment)
Before you update make a backup of your BE:
#save BOOT Environment
beadm create (type the name for this backup here)
Add dev to the package manager environment to get the latest updates:
http://pkg.opensolaris.org/dev
run package manager from the menu and choose update all (555 packages in my case)
If you get an error that it cannot install them, you probably forgot to check the radiobutton to set dev as Preferred Repository
Update to specific build:
So, can anybody advise how the system can be upgraded to chosen dev version?
Ok, here is the procedure:
Starting from OpenSolaris 2009.06 (snv_111b) active BE.
1) beadm create snv_111b-dev
2) beadm activate snv_111b-dev
3) reboot
4) pkg set-authority -O http://pkg.opensolaris.org/dev opensolaris.org
5) pkg install SUNWipkg
6) pkg list 'entire*'
7) beadm create snv_118
8) beadm mount snv_118 /mnt
9) pkg -R /mnt refresh
10) pkg -R /mnt install entire@0.5.11-0.118
11) bootadm update-archive -R /mnt
12) beadm umount snv_118
13) beadm activate snv_118
14) reboot
Now you have a snv_118 development environment.
You need a jump-off BE that has a lower build then the one you want to install.

Set Static IP on OpenSolaris
ifconfig nfo0 plumb (do a ifconfig -a to see if it is nfo0 or anything else)
ifconfig nfo0 10.0.0.3 netmasks 255.255.255.0 up (I decided to give it 10.0.0.3)
echo "10.0.0.138" > /etc/defaultrouter (My router IP)
echo "10.0.0.0 255.255.255.0" > /etc/netmasks
dawbckup:/etc# cp nsswitch.conf nsswitch.conf.original
dawbckup:/etc# cp nsswitch.dns nsswitch.conf
Remove the file if present: /etc/dhcp.nfo0
edit /etc/hosts
add 10.0.0.3 dawbckup
vi /etc/defaultrouter
(add '10.0.0.138' on its own line)
vi /etc/hostname.nfo0
(add dawbckup)
everything should be okay when you'll reboot,
=========== reset config =====
In contemporary (Solaris 8/Solaris 9) days, "sys-unconfig" is the correct answer
==============================
step 1 select NIC nfo0
step 2. setup nameservers
edit /etc/resolv.conf
domain qstudio.nl (to get rid of the FQDN message)
nameserver 195.121.1.34 (Use DNS from your Internet Provider)
nameserver 195.121.1.66
step 3.Switch to using the DNS servers...
dawbckup:/etc# cp nsswitch.conf nsswitch.conf.original
dawbckup:/etc# cp nsswitch.dns nsswitch.conf
dawbckup:/etc# svcadm restart svc:/network/dns/client:default
Step 4: Switch to a static IP
gedit /etc/nwam/llp
change the 'nfo0 dhcp' to 'nfo0 static 10.0.0.3/24'
svcadm restart svc:/network/physical:nwam
step5.
edit /etc/hosts
add 10.0.0.3 dawbckup
vi /etc/defaultrouter
(add '10.0.0.138' on its own line)
(Hmmm, I realise I used two ways to edit/change files, one time using vi and started with "echo" Whichever you prefer)
step 6 (I did not need to do step 6, but it was mentioned by a user)
# pfexec svcadm enable svc:/network/physical:default
# pfexec svcadm restart network/routing-setup
ifconfig nfo0 10.0.0.3 netmasks 255.255.255.0 up (I decided to give it 10.0.0.3)

Asus M4N78-Pro works with OpenSolaris 2008.11
I run opensolaris on my new asus board. Had some difficulty with the Gigabit driver not being recognized but used the latest driver from the website mentioned by the device driver utility (http://homepage2.nifty.com/mrym3/taiyodo/eng/)
I first tried to set this MCP78S (Geforce 8200 Ethernet) as a nge0 device but had trouble with the reverse bug with the MAC address.
I then decided to set it up as nfo0 with the nfo-2.6.3.tar.gz.
Installation following the readme provided with the tar file went OK and revealed itself as pci10de,760.

OpenSolaris - slow boot fix
If you've installed opensolaris 11/08 and unhappily found it's slow as mud to boot..
# edit /rpool/boot/grub/menu.lst
# look for the lines like.. below and remove them..
splashimage /boot/solaris.xpm
foreground d25f00
background 115d93
# next find the kernel line and change from
--kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS,console=graphics
++kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS
My boot time went from longer than 5 minutes to under 30 seconds. and you get to see the svc errors :)

After this I downloaded the Iscsi Initiator for windows XP and used the instructions from Microsoft. At the end the volume is shown when you go to My computer -> Manage -> Disk management. You now can create partitions add drive letters and format just like a regular disk within Windows.
