Someone has suggested to use jumpstart, but this was not my case: I just had to move 1 machine filesystem
on a new one (SparcClassic -> Sparc5).
good suggestions have been:
- check for '/etc/path_to_inst'
in fact this file is HW dependent and should be updated by 'drvconfig' command.
But if you boot from cdrom and run 'drvconfig -r <root_partition>' the command
pretends to update '/etc/path_to_inst' and fails because /etc is mounted on cdrom
(read-only filesystem). So I've done a copy of '/tmp/root/etc/path_to_inst' that seems
to be a good one. Furthermore (on Solaris 2.3 only?) drvconfig seems to have some
problem about <root_partition> specification; so the suggested sequence is:
mount /dev/dsk/c0t0d0s0 /a (disk root partition)
cd /a
drvconfig -r devices (drvconfig -r /a/devices doesn't work!)
- run 'disks' and 'tapes' (-r <root_partition>)
devlinks adds /dev entries for miscellaneous devices and pseudo-devices only so
the command 'disk' is needed to create /dev/dsk and /dev/rdsk entries.
disks -r /a
tapes -r /a
devlinks -r /a
halt
boot -rs
This are the results cloning machine with different HW but same architecture (sun4m). As suggested
I will never try to do un upgrade between different platforms (sun4m -> sun4u). There are too many stuffs
(/usr/kvm among them) that are platform-dependent.
