How to clone enter harddisk on Sun Sparc20?

Hi mates,

well before posting my problem, i really searched hi and low for some ideas, but sad to say none of them worked, including dd command.

My problem is that i have 2 harddisk, 1 in use and 1 for spare. The one im using got crashed and now im using my spare harddisk with all the engraver and rip software in it.

I would like to clone the good harddisk to this new harddisk that i got. Just in case another crash happens.

The only thing i can share is that i have a SunSparcstation 20. please refer to the attach for the system. And by the way i don't have a CD rom installed.

anyhelp would do. and please if you need other info please do let me know.

What OS release are you using ? How did you boot the SS20 ?

/dev/sda?? on solaris ? pls check

1. Make sure the source and destination disk have the same disk geometry
2. Become superuser
3. Create /reconfigure file on the sys so that the system will recognize the clone disk to be added when it reboots. # touch /reconfigure
4. Shut down the system. # init 0
5. Attach the new hard disk to Secondary IDE and set cable select
6. Boot the system. ok boot
7. Use the “dd” command to copy the master disk to the new hard drive.
# dd if=/dev/rdsk/master-harddisk of=/dev/rdsk/new-harddisk bs=blocksize
8. Wait for the hard disk to clone finish, and check the new file system.
# fsck /dev/rdsk/new-harddisk
9. Mount the new-harddisk’s root file system
#mount /dev/dsk/new-harddisk /mnt

10. Edit the new-harddisk /etc/vfstab to reference to the correct device name using VI
Changing all instance of new-harddisk to master-harddisk

11. Unmount the new-harddisk.
#umount /mnt
12. Shut down the system # init 0
13. Remove the master hard disk , replace with the new-hard drive

I would suggest having the source disk filesystems being mounted read-only here, or at least being in a quiet single user mode.
