I am cloning a Solaris Sun os 4 machine with two disks using dump and restore.
It had successfully created dump and dump file has been restored onto secondary disk successfully.

Boot block installed successfully. Now If I try to connect the secondary disk onto another machine it is not booting.

May I know the reason or anything required to be done?

If I try to connect the secondary disk onto another machine it is not booting.

First you need to reinstall the boot loader of the second machine onto the second disk that you want to boot off.

Secondly, you need to boot the second machine from a Solaris OS CD to find out the control ID, which might be different from the one in vfstab, then you need to change it.

At the OK prompt or boot from cd and check format to see the disks
Then mount the partition from the HD where /etc is and look at vfstab

As the comment in the other what is the HW for the original OS boot versus the one you are trying to boot?

Different systems have different drive assignments some have scsi1,3 some have 0,2 even though both might have two disk inserts...

I.e, older spare 20 had 1,3 while spare 5 ultra I think used the 0,1....


Solaris 4 is a rather old OS mid to late 90s.

Could you please be specific in asking hardware configurations?

What hardware info you needed? Hd or processor??

System info sun4m sun4c etc.
I think your issue is that your system is partitioned
/
/usr
And you only clone the / partition

Most commands are under /usr
The system boots because several essential commands are under /bin
Look at the boot disk partition table and make sure your new disk I partitioned in the same way, then clone each partition one at a time.

I think that should be my problem, so accordingly I should partition as that of original disk. I would do this operation and get back with the results.

I found only cd and pwd working after cloning.
But it seems there is no prtvtoc like command to copy entire partition table in sun box 4.
