migration SO

[castro_2]

I have two vg's the vg00 with one disk the 4 GB and vg01 with one disk the 8 GB. The last disk is free and the vg00 is almost full. I want to use to create a SO because the other disk (4GB) I need to another system this is the reason that I don`t do a vgextend.
What is the best way to do it?
Thanks

What's an SO?

If I'm understanding this correctly, you want to take the 4GB vg00 disk out of the first system and use it in another? Use Ignite-UX to take a backup of your existing vg00, then restore it onto your 8GB disk, which will become your new vg00.

What about adding the 8GB as another mirror? Then reboot - using the 8gb disk, remove the 4GB from the mirror set, shutdown system, then pull the 4GB disk out.

You need to do something like this to mirror the root:

Mirrored the root lvols:

pvcreate -B /dev/rdsk/c3t6d0
vgextend /dev/vg00 /dev/dsk/c3t6d0
mkboot -l /dev/rdsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c3t6d0
/usr/sbin/lvlnboot -b /dev/vg00/lvol1
/usr/sbin/lvlnboot -s /dev/vg00/lvol2
/usr/sbin/lvlnboot -r /dev/vg00/lvol3
lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol5 /dev/dsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol6 /dev/dsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol7 /dev/dsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol8 /dev/dsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol9 /dev/dsk/c3t6d0
lvextend -m 1 /dev/vg00/lvol10 /dev/dsk/c3t6d0

Hi,

Apart from pete's suggestion, you can also use Mirror.
(if you have mirror unix software)
remove the vg01 (vgremove /dev/vg01)

#vgscan -a -v
#lvextend -m 1 /dev/vg00/lvolx /dev/dsk/cxtxdx
(where cxtxdx is the 8Gb disk)

repeat the above for all lvol's in vg00

set the boot path to 8GB disk, after booting you can remove the 4GB disk

Hi,

yes, break the mirror and set the boot path to 8gb disk

[castro_2]

How can unmirror the disk the 4 GB?
lvreduce -m /dev/vg00/lvXX
and the Boot Data.

Hi,

For example, if /dev/vg00/lvolx is on /dev/dsk/cxtxdx and you want to move it to /dev/dsk/cytydy,
you can do:

lvextend -m 1 /dev/vg00/lvolx /dev/dsk/cytydy

and then

lvreduce -m 0 /dev/vg00/lvolx /dev/dsk/cxtxdx

[castro_2]

and the lvlndisk -v only show one disk?
Thanks

[Ravi_8]

#lvlnboot -v

[castro_2]

yes, sorry lvlnboot -v only show me one disk o 2 disks

[Ravi_8]

Could you set the primary boot path to 8GB disk and boot?

[castro_2]

When I do the mirror the command lvlnboot -v show me 2 disks 4 GB and 8 GB, When I unmirror
Only want to show me the 8 GB, I do the command lvlnboot -v only show me 1 disk 8 GB .
Thanks

Ready to try the Ignite approach yet?

How you set the primary boot path to 8GB disk and boot?
Thanks

[James R. Ferguson]

Hi:

In answer to your question of how to set the primary boot path:

# setboot -p 10/0.6.0

...Use 'ioscan -kfnC disk' to relate the above path to the proper disk on you system.

See the man pages for 'setboot' for more information.

Regards!
