How to take 18gig and push it to 30gig 1

[Sirmarsh]

Hello all.
I'm new to a Sys-Admin role, so forgive me. Here is my situation thou. I have a 18gig drive that runs Solaris 8. This drive is old and needs to be upgraded. I have 3 new 222r's in that are 30gig drives. My questions is. What is the best way(step-by-step doc) on take the information/files from the 18gig and placing them onto a 30gig drive? This is going to be my main producton web server. I have a few days to get this done, but dont have a clue as how to get it done. Any help would be greatly welcomed.

Thanks
sirmarsh

I had to do something similar a while back. The system I had was mirrored. If your system isn't mirrored just miss out those steps. A cut and paste into a separate document is advisable.

1 Break the mirrors.

# metadetach –f d1 d12
# metadetach –f d2 d22
# metadetach –f d3 d32
# metadetach –f d4 d42
# metadetach –f d5 d52

1.1 Replaces current Disk 2

1.1.1 If the disks are hot swappable

Take the current disk 2 out the slot.

Insert the new 36GB disk in the slot.

Run devfsadm –c disk

1.1.2 If not

Shutdown system

Take the current disk 2 out the slot.

Insert the new 36GB disk in the slot.

Reboot

Run devfsadm –c disk

1.2 format the new disk

Use format to create the partitions wanted on the target drive. New numbers are approximate.

1.2.3 Create the Database State Replicas
# metadb –a –c 3 –f /dev/dsk/c0t1d0s7
1.2.4 Create submirrors and initial one-way mirrors
# metaclear d12
# metainit –f d12 1 1 c0t1d0s0
# metainit d10 –m d12
# metaroot d1
# lockfs –fa #locks currently mounted file systems i.e. the one with the data

# metaclear d22
# metainit –f d22 1 1 c0t1d0s1
# metainit d20 –m d22

# metaclear d32
# metainit –f d32 1 1 c0t1d0s3
# metainit d30 –m d32

# metaclear d42
# metainit –f d42 1 1 c0t1d0s4
# metainit d40 –m d42

# metaclear d52
# metainit –f d52 1 1 c0t1d0s5
# metainit d50 –m d52

# newfs /dev/md/rdsk/d10
# 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.

Thank you for your input. I will go home and build a test bed for this, and try it out. Again, thanks for the quick reply sir.


Thanks,
