How to clone solaris 10 machine
I am pretty novice to solaris and I need to clone solaris 10 machine to a shared network path, and then take the image to duplicate to another machine.
I tried using dd but got stuck at the start,
dd if=/dev/rdsk/device-name of=/dev/rdsk/device-name bs=block-size
Here, how to identify which is the source device-name.
Because under dev/rdsk I found number of entires as below,

OK, you have one file system with your Solaris OS
c0t0d0s0
and another with everything under /export/home (user's home directories)
c0t0d0s7
Therefore, the source device would read: /dev/rdsk/c0t0d0s0
And if you want to copy home data, too: /dev/rdsk/c0t0d0s7
c0t0d0s0
and another with everything under /export/home (user's home directories)

Which FS type do you use for your filesystems?
mount | grep c0t0d0s
Depending on the FS type you can use diffenrent backup (and recover) methods like dumping a filesystem, creating a FLAR and so on ...

Have you ever used ufsdump?
I'd suggest to use ufsdump to backup you disk. You can even do it when running OS by using snapshop:
You can safely run ufsdump with snapshot on a live system and transfer the resulting dump (a file) onto another system
Create ufsdump from root filesystem with snapshot:
Transfer (copy) the dump file onto the other system and mount the new root filesystem under /mnt
Now, extract the (whole) dump into it:
If you are short with disk space, create a comressed dump instead:

Create ufsdump from root filesystem with snapshot:
# ufsdump 0f /var/tmp/root.dump `fssnap -F ufs -o raw,unlink,fs=/var/tmp/BS /`
You will have to make sure that /var/tmp is NOT in the filesystem you want to back up (e.g. your root filesystem). Otherwise, use another directory, like /export/home/BS. BS stands for "backing store".Transfer (copy) the dump file onto the other system and mount the new root filesystem under /mnt
Now, extract the (whole) dump into it:
# cd /mnt ; ufsrestore xf /tmp/root.dump
and install the boot block (change c0t0d0s0 to your root device): # installboot /usr/platform/`uname -m`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0
If you are short with disk space, create a comressed dump instead:
# ufsdump 0f - `fssnap -F ufs -o raw,unlink,fs=/var/tmp/BS /` | gzip -9 > /var/tmp/root.dump.gz
and extract (on the other system) with # cd /mnt ; gzcat /tmp/root.dump.gz | ufsrestore xf -

Thanks for your detailed answer Hanno.
I have not used usfdump anytime before.
Is backup/clone used interchangeably, because I wanted to clone the machine.
My Source file system has /var/tmp so I will have to use /export/home/BS. In this case is the following command correct?
# ufsdump 0f /var/tmp/root.dump `fssnap -F ufs -o raw,unlink,fs=/export/home /BS /`
But nothing is happening with this command.
Or should I need to use ufsdump 0f /var/tmp/root.dump `fssnap -F ufs -o raw,unlink,fs=/export/home /BS /dev/rdsk/c0t0d0s0???
Next you have asked me to transfer to the destination system so here my queries are,
1) What should be the configuration of the destination system, like does it have Solaris 10 running on it?
2) Where to copy file I mean which location in the destination machine?
If my directory is /export/home/BS how the rest of the command would change.
Please do the needful.

1. Make sure you use backticks and not single quotes. Maybe, you want to copy-and-paste the command.
2. My typo: it should read bs (for backing store) not fs.
The command
To understand better, yo may do it this way:
a) Create the snapshot:
fssnap -F ufs -o raw,unlink,bs=/export/home /BS /
b) Dump (backup) from the device that just got displayed (substitute 'x' with the correct number):
ufsdump 0f /var/tmp/root.dump /dev/fssnap/x
c) Dsiplay existing snapshot debvices:
fssnap -i
d) Delete the snapshot device:
fssnap -d /
or
fssnap /dev/fssnap/x

2. My typo: it should read bs (for backing store) not fs.
ufsdump 0f /var/tmp/root.dump `fssnap -F ufs -o raw,unlink,bs=/export/home/BS /`
Do not useufsdump ... /dev/rdsk/c0t0d0s0`
as you will be using the snapshot and not the disk device to read from.The command
fssnap -F ufs -o raw,unlink,bs=/export/home/BS /
creates a snapshot /device) from which will be read.To understand better, yo may do it this way:

fssnap throwing errors as device busy.
I ran this command in export/home folder, that time it showed me something like this

next time I ran this under root but it showing me the following error.
#fssnap -F ufs -o raw,unlink,bs=/export/home /BS /

Is the snapshot done? if so how to check?

No. This looks like you are saving the dump file onto the same filesystem you are reading from.
You need thre pieces:
1. the file system to back up /
2. the backing store (must not reside on 1.)
3. the dump file (must not reside on 1.)

You said you wanted to 'clone' -- which means you will put stuff on an new (usually blank) disk.

Thanks a ton, snapshot and dump got created under /export/home, I am worrying about the statement of yours on the same post,
Stmt:Transfer (copy) the dump file onto the other system and mount the new root filesystem under /mnt.
Ok fine I have a new disk or a new system which is usually blank.
Should I install Solaris 10 in that disk/new system and copy the dump only to follow your steps?
If so where to copy I literally mean which location in the new disk/new machine? Is it on the root or root/tmp where?
Second concern is how to mount the root filesystem? Is that Ok If I follow below steps to mount? Please answer all my resentments.
# newfs /dev/rdsk/c0t1d0s0
# fsck /dev/rdsk/c0t1d0s0
# mkdir /legacy
# mount /dev/dsk/c0t1d0s0 /legacy

Now, extract the (whole) dump into it:
What you wrote is fine, but fsck is not required.
As I wrote earlier (I will add a few more details here) you go into the (blank) root filesystem to restore your dump:
Don't forget to install the boot block:
Now you have a fresh copy of your root file system on c0t1d0s0 which is bootable.

This infers I should install Solaris 10 in the new system isn't it?
But if I install the new system with Solaris 10 it will be having some file system right, how should go about it?
Should I place dump file under root / or export/home in the new machine?
These above are my main points to ponder.

If you put the dump onto your second disk (as descibed in my prior post) you can put this disk in another system as first disk to boot from -> a clone (or copy) of your original system.
And that is what you wanted to acomplish, right?

This could also serve the requirement if there are two disks in the same machine. But what if there are two machines and each only one disk? What you said was right but right now my machine has only one disk and I will have to dump the file onto another machine.
How to proceed in this scenario?
How to proceed in this scenario?
a) The dump file can be written to any device you have (tape, disk, NFS-mounted diretory, SaMBa share, etc.)
b) If you have only a single drive target machine, you will have to boot that machine over network or from CD/DVD as you cannot create a new root filesystem on a "live" disk/filesystem

b) explains that you cannot overwrite a root filesystem when it's active!
It must be quiescent (unused)
It must be quiescent (unused)
1.) The steps (newfs, ufsrestore) have to be performed on the target machine
2.) You have to run (boot) an OS that has ufsrestore (any Solaris you may have)
3.) ufsrestore will recover all files from your full backup (ufsdump with level 0) to a (new and empty) filesystem
You can either copy (scp) the dump file or mount via NFS.
If you have an existing server you want to replace the root filesystem, you can
a) transfer (copy) the dumpfile to any place outside the root filesystem
b) Boot the system from another disk, network or CD/DVD
c) newfs the root filesystem and mount under /mnt
cd into /mnt and extract your dump using ufsrestore.
A side note:
You can easily examine the dump using
ufsrestore if /export/home/root.dump
Now, you can user commands like ls, pwd and cd to move around and look at backup contents. quit will leave. More can been learnt with "man ufsrestore"
2.) You have to run (boot) an OS that has ufsrestore (any Solaris you may have)
3.) ufsrestore will recover all files from your full backup (ufsdump with level 0) to a (new and empty) filesystem
You can either copy (scp) the dump file or mount via NFS.

This is under export/home
# ls -lh
total 16219376
-rw------- 1 root root 7.7G Oct 26 18:30 BS
drwx------ 2 root root 8.0K Oct 19 15:39 lost+found
-rw------- 1 root root 7.7G Oct 25 16:17 root.dump
If I SCP the dump file (root.dump) onto target machine why should I do b), because target machine is already running with Solaris 10. What does the disk, cd?DVD contains here?
What do u mean to say boot from CD/DVD when I have OS already installed in the target machine?
I will transfer the dump file to the target machine and start mounting it, will it not work?

Yes exactly How do I go with target machine configuration?
Before booting Should I need an empty machine without any OS?
If there is nothing in the machine How to transfer the dump file?
What I understand is
a) Get an empty machine (Target machine)with no OS
b) Boot an OS from CD/DVD
c) transfer the dump file
d) then perform ufsrestore and install boot
Is that correct?

I totally agree having another new drive instead of new target machine.
I bought a new hard drive.
I did connect this new drive, using format, fdisk and partition.
Now How to transfer the dump file onto this new drive (any command like cpio if so how)?
Literally how to switch between two drives?
Remember I have not mounted and created any files system because as per your steps I need to transfer (copy) the dump file onto another system and then mount the new fs, restore and the install boot.

I just posted an answer to your new question.

Thanks for the great response
There are much better ways to do this (like ufsdump, zfs send, etc.)
But if you insist ;-)
Which is your (root) disk?
Look which disk is used for which file systems
# df -hl
Now look for the devices that the filesystems /, /usr, /var, /opt, /export etc. are using
The osurce device should be someting like /dev/rdsk/c0t0d0s0
