Need to move Oracle Software to another VG

[Gulam Mohiuddin]

I have two disks in our system one in vg00 and another in vg01.

I have installed Oracle9i software on vg01.
Now, I need to move Oracle9i from logical volume /dev/vg01/lvol01 in VG01 to VG00.

After that I need to remove VG01 or create vg01 on the same disk where is VG00.

Also, is it possible to move Volume groups to different disk?

# strings /etc/lvmtab
/dev/vg00
en0QAQ
/dev/dsk/c0t6d0
/dev/vg01
en0QAZ
/dev/dsk/c0t5d0

Thanks,

Gulam.

Before you start , back up the binaries to tape. Remove the tape so you can't accidently erase it.

Its usually not a great idea to have anything but the OS stuff in vg00. Thats just normal practice.

The general procedure would be:

vgexport -m /etc/lvmconf/vg01 -s /dev/vg01

vgreduce /dev/vg01 /dev/dsk/c0t5d0

create a new vg or extend vg00 to include disk /dev/dsk/c0t5d0.

Then:

vgexport -m /etc/lvmconf/vg00 -s /dev/vg00

vgimport -m /dev/lvmconf/vg00.map -s /dev/vg00

That should import all lvm structues.

Its important to have the backup in case you make a mistake.

Hi,

You should have enough space left on you "root" disk inside vg00

# lvcreate -L 8000 -n lvol9 /dev/vg00
change the size and the name if you like :-)
# newfs -F vxfs /dev/vg00/rlvol9
# mount /dev/vg00/lvol9 /mnt
# cd /orahome9i
# find . | cpio -pcmudv /mnt
# cd /
# umount /orahome9i
change the /etc/fstab to point /orahome9i to the new lvol.
# umount /mnt
# mount -a
vgexport vg01 and add the disk to vg00 with a vgextend.

Best regards,
Robert-Jan

1. mount temp mount point on new lv on vg00
mount /vg00/lvoracle /oramove
2. copy all files on /orahome9i
cp -r /orahome9i/* /oramove
3. unmount /orahome9i
umount /orahome9i
4. mount new /orahome9i on new lv on vg00:
mount /vg00/lvoracle /orahome9i
5. edit /etc/fstab to reflect the changes on filesystem.
