[!!] Summary: Adding 2.1G system disk

You may recall my request for feedback on replacing a 1.05GB system disk with a 2.1GB
device.

Following responses from various people, I've just completed what I believe to be a
successful upgrade.

I had a full complement of SCSI devices, but elected to temporarily replace an
existing drive (sd1) with my new disk whilst files were transferred from sd0.

Having moved files/directories I knew I'd need from sd1, I modified /etc/fstab to
exclude sd1, and shut the system down. I then installed the 2.1GB disk as sd1 and
rebooted. I used format to define the disk partitions and then newfs'd them. I then
mounted each new partition (using /part1a and /part1g mount points in /).

The file transfer from old disk to new was easy: (using sd0a as the example)
  cd /part1a
  dump 0f - /dev/rsd0a | restore rf -
The / and /usr partitions were moved across.

The only tricky part came in trying to install bootstrap information to the drive.
The normal installboot command goes something like:
  cd /usr/kvm/mdec
  installboot -vlt /boot bootsd /dev/rsd1a

This failed (since I was working across disks) and was corrected by:
  cd /part1g/kvm/mdec
  installboot -vlt /part1a/boot bootsd /dev/rsd1a

/etc/fstab was editied to reflect the new file systems.

I also took the opportunity to move the /home partition from /dev/sd0h onto another
disk, /dev/sd1c. Fortunately, I had an almost empty disk to use as a temporary
repository for the files off the /home partition.

All-in-all, a very successful afternoon's work.

BUT!! It would not have been so easy had it not been for the invaluable contributions
of the following people, particularly Ingolf Markhof. If I have missed anyone out, I
apologise....these are the messages I received directly.
