# newfs /dev/md/rdsk/d30
# newfs /dev/md/rdsk/d40
# newfs /dev/md/rdsk/d50
1.2.5 Copy Data
Make directories for the new partitions on the source drive. (not needed for swap and backup)
# mkdir /newroot
# mkdir /newvar
# mkdir /newopt
# mkdir /newmulti
Mount each of the new filesystems from the source drive (not needed for swap and backup)
# mount /dev/md/dsk/d1 /newroot
# mount /dev/md/dsk/d3 /newvar
# mount /dev/md/dsk/d4 /newopt
# mount /dev/md/dsk/d5 /newmulti
Enter the following command for each of the filesystems to move:
# ufsdump 0f - /dev/rdsk/c0t0d0s0 | (cd /newroot;ufsrestore xf -)
# ufsdump 0f - /dev/rdsk/c0t0d0s3 | (cd /newvar;ufsrestore xf -)
# ufsdump 0f - /dev/rdsk/c0t0d0s4 | (cd /newopt;ufsrestore xf -)
# ufsdump 0f - /dev/rdsk/c0t0d0s5 | (cd /newmulti;ufsrestore xf -)
When each dump is complete answer ‘Y’ to the “set owner/mode for .?” and “Directories already exist, set modes anyway? (y/n)” questions.
1.2.6 Update /etc/vfstab and make bootable
Update /etc/vfstab on the newroot partition. NOTE: This is extremely important. Make sure you are on the target drive. Leave the source /etc/vfstab as is.
# cd /newroot
The target /etc/vfstab should look something like.
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
fd - /dev/fd fd - no -
/proc - /proc proc - no -
/dev/md/dsk/d10 /dev/md/rdsk/d10 / ufs 1 no -
/dev/md/dsk/d20 - - swap - no -
/dev/md/dsk/d30 /dev/md/rdsk/d30 /var ufs 1 no -
/dev/md/dsk/d40 /dev/md/rdsk/d40 /opt ufs 2 yes -
/dev/md/dsk/d50 /dev/md/rdsk/d50 /multi ufs 2 yes -
swap - /tmp tmpfs - yes -
1.2.7 Tidy up filesystem
Unmount each of the filesystems mounted:
# umount /newroot
# umount /newvar
# umount /newopt
# umount /newmulti
Run the installboot program to install the boot blocks on the target drive.
# cd /usr/platform/`uname -i`/lib/fs/ufs
# installboot bootblk /dev/md/rdsk/d10
1.2.8 Shutdown, set boot disk and reboot
Shutdown the system. /usr/sbin/shutdown -y -i0 -g0
From the ok prompt:
ok setenv boot-device disk1 (reassign the boot device from the source to the target)
ok reset (recycle the prom monitor)
As a confidence check we might want to boot from the new disk to check it works before continuing.
ok boot (boot from the target drive/new boot device)
1.3 Replace Current Disk 1
1.3.1 If the disks are hot swappable
Take the current disk 1 out the slot.
Insert the new 36GB disk in the slot.
Run devfsadm -v (or drvconfig and disks) to identify the new disk.
1.3.2 If not
Shutdown system
Take the current disk 1 out the slot.
Insert the new 36GB disk in the slot.
Reboot
Run devfsadm -v (or drvconfig and disks) to identify the new disk.
1.4 format the new disk
Use format to create the partitions wanted on the target drive.
