How do I use ufsdump to clone a larger scsi disk from a smaller scsi disk?

How do I use ufsdump to clone a larger scsi disk from a smaller scsi disk? Here is what I need to accomplish.I have an E250 that my OS disk is 9GB and I want to install a 147GB disk (can't get 9GB disks easily).

At the moment I have 3 disks (1x9GB and 2x18GB) in the 6 slot raid system. I am going to change out all 3 disks for 147GB or 73GB disks. partitioning the 2 that don't have the OS on them will be easy enough. I am concerned about the proper nomenclature for ufsdump of the hard disk that has the root file system on it.

This disk also has swap, opt and usr.

The other two disks are mirrored and contain data.

I have the slides to install the new scsi hard disks into the 6 slot raid of the E250 so that they call all be in the raid at the same time.

Do I have to bootup on the Sol8 CDdisk1 as single user?

Should I partition the new scsi hard drives first with the new sizes?

What is the proper nomenclature for transfering 18GB hard drive to 73GB hard drive?

Thanks

best to boot single user with CDROM

then partition ( or slice up ) the new disk the way you like

just make sure there is enough space in the slice to hold all the old data

newfs the new slices

mount them up

mkdir /tmp/1

mount /dev/dsk/c0t0d0s0 /tmp/1

cd /tmp1

ufsdump 0f - / | ufsrestore rf -

repeat for each partition like /var, /usr, /export/home

then install the boot block

installboot /usr/platform/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0

You might need to update the disk path info

devfsadm -p /tmp/1/etc/path_to_inst -r /tmp/1

check your /tmp/1/etc/vfstab is correct for the new boot environemtn

touch /tmp/1/reconfigure

that should be it ... time to reboot
