Hi,
Using Solaris 2.9 with a SVM controlled boot disk I am trying to clone a
boot disk from one E250 to an identical E250. The drives are identical.
I do the following on the "source E250"
prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t8d0s2
dd if=/dev/rdsk/c0t0d0s2 of=/dev/rdsk/c0t8d0s2 bs=1024k
fsck slices on c0t8d0
Then I remove the disk in slot 1 from the source E250 and put it in slot 0
of the target E250.
I boot it up and the boot loads Solaris and then panics because it cannot
mount root fs. I have looked at tons of websites and they all say the dd
should work. I have tried to open a case with Sun support and they say that
dd cloning is not supported by Sun. I have successfully done this ~200
times with Solaris 2.8 and disk suite controlled boot disk. The only think
I can think of is that SVM somehow uses a SCSI "WWN" to reference the boot
partition...
Any ideas would be greatly appreciated.
- Win
