Actually, I've tried both paths: 1) adding a 2nd disk, 2) extending existing
disk.
In case of 2), the problem is that it does not boot up correctly.
Below is the procedures I've followed:
1. create backup of the disk.s10hw2: mount disk.s10hw2 & run 'ufsbackup'
2. create empty file of about 1GB size: 'dd if=/dev/zero of=new.img bs=1024
count=1000000' & mount new.img (to /dev/lofi/1) & run 'newfs /dev/lofi/1'
3. restore backup onto new image: run 'ufsrestore'
4. make new image bootable: 'dd if=bootblk of=/dev/lofi/1 bs=1b oseek=1
count=15 conv=sync'
The only difference from yours is procedure 4.
It's because 'installboot' refuses to work on loop devices (i.e. created by
lofiadm).
I see that the new image mounts & unmounts correctly within UltraSPARC
machine.
But I can't get it booted up correctly on both the M5 and the opensparc
tools.
Any suggestions?
