I have a Solaris 10 machine, with that I have created a back up dump file in export/home. Now I have connected another hard drive to the same machine for restore. I have used Ufsdump to create dump file.

What are the next steps once I connect another empty hard drive?
Do I need to configure or mount or what needs to be done so that I copy the dump file into this hard drive and ufsrestore?

In the following, let's assume your boot disk is c0t0d0 and the new (second) disk is c0t1d0
a) Add the new disk (assumed you did boot with "reconfigure" already)
    Either partition the disk for filesystems using "format" program
    or (if the disk is the same as your original disk) copy the vtoc
    prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t1d0s2

Open in new window

   This defines how the filesystems on the disk will be laid out
b) Create the desired filesystem(s) on you disk with newfs, e.g.
     newfs -f ufs /dev/rdsk/c0t1d0s0

Open in new window

c) mount the new filesystem (let's use /mnt here):
    mount /dev/dsk/c0t1d0s2 /mnt

Open in new window

d) Go into mount pount and extract ufsdump
    cd /mnt
    ufsrectore xf /export/home/dump-file

Open in new window

the first volume is 1 -- if you have only a single volume, it's always 1

The output for ufsrestore is as below,

# ufsrestore xf /export/home/root.dump
Warning: ./lost+found: File exists
You have not read any volumes yet.
Unless you know which volume your files are on you should start with last volume and work towards the first.
Specify the next volume #:

if you put in
  1
and press return it should start extracting the files.

create a reconfigure file on the new root fs:
touch /mnt/reconfigure

Open in new window

shut down, put the new disk into target machine and reboot.
Note: This works only if the machines are not too much different from each other!

Thanks a ton Hanno, I got it working with similar hardware configuration.
You have been a constant support in getting this done. I am grateful to you.

Under what hardware differences this would work?
If there are differences in hardware what to use to clone?

This particular task I did as a mock drill, which was just a raw machine with some files. But if it were to be a full fledged machine with various application running on it then, will the applications work after cloning in target machine by this procedure?

The problem arises when the hardware is very much different which may create problems with certain drivers upon booting the new machine.
Once the machine is up and runnind all applications will work fine.

What is the alternate command for fssnap in Solaris sun OS 4.1.3? Or In the procedure from the two posts what that could change for 4.1.3? I have asked this in another post you can reply there if you wish to.
