VGREMOVE

[Arun Jain]

Hi All,

I have one server running HP-UX 11.11. Last one due to some testing purpose, one VG was created consisting 8 PV and 10 LV. total size of the VG is 1.7 TB.
now the testing is over and the same is to be removed. Post that one new VG and LV is to be created but this time the zie of the LV is 250 GB.
Please suggest, whether I should go for vgexport method or vgremove method.

In both the cases Plz provide the steps also.

Thanks & Regards :
Arun

Hi

It is better to run "vgexport" rather than removing all LV's,PV's and vgremove.

Do
#vgexport

Then,

CReate your new VG and LV

Hi Arun,
you can remove the LV and or you can export the VG.

vgchange -a e /dev/vg-name
lvremove /dev/vg-name/lvname

or
vgexport /dev/vg-name


Thanks & Regards

Hi Arun,

vgexport will remove the volume group with one step but without modifying the logical volume information found on the physical volumes.

vgexport OLDVG

Create new VG:
mkdir /dev/VGNAME
mknod /dev/VGNAME/group c 64 0x0?0000 (be careful about the minor no)
pvcreate -f /dev/rdsk/c?t?d?
(remove the old vg info from the disks)

vgcreate VGNAME /dev/dsk/c?t?d?
(choose the correct values for the PE size, etc).

vgchange -ay VGNAME
lvcreate -L 256000 /dev/VGNAME/lvolname
