Hi Sun system managers,
Thanks to Chin Fang, Mark Ashley, Casper Dik, Kelvin White, and Devendra Murmu.
The original question:
> I only have ONE Solaris 2.4 system which is an important data server, and I
> have many Solaris 2.5 and 2.6 systems. Since the Solaris 2.4 is a 1GB system
> disk with around 8 disks (RAID 5 disksuite 4.0), I want to replaced it with

> transfer everything from the 1GB system disk to 2GB disk except the boot blook,
> then the 1GB system disk got burned, at least I can smell it :(, by touching
> something with the IC/pin of one side of the disk !!!
> My question is can I connect the good 2GB disk (ie, has Solaris 2.4 in it
> except boot block) with one of my Solaris 2.5 (or 2.6) system , then install
> the Solaris 2.5/2.6 bootblock and it still work and boot up the Solaris 2.4
Casper sadi "The Solrais 2.5 and later bootblocks are not compatible with 2.4"
but Kelvin said "yes! installboot is ok to do this way!". Well, I didn't
dare to try to install a Solaris 2.5 bootblock to a 2.4 system, and here is
Since the 2GB disk already has the bootblock in /usr/lib/fs/ufs, I should
boot Solaris 2.5 CDROM, mount the 2GB disk (contains 2.4 system but without
bootblock) to /tmp/mnt and then:
/usr/sbin/installboot /tmp/mnt/usr/lib/fs/ufs/bootblk /dev/rdsk/c0t3d0s0
I haven't really tried the above because I was so urgent on that Sunday evening,
I just simply installed Solaris 2.4 into the other system (this system has
SunOS OS installed before), and mount the 2GB disk as a second disk, and
install the bootblock.
