Hope the VG having 2disks currently & you want to mirror the lvs in this vg with two new disks.


1. pvcreate newdisks
2. add new disks to existing vg with vgextend command.
3. mirror lvs using lvextend command
4. verify the mirroring using lvdisplay + vgdisply.

What is the exact command that I need to execute for create LVm with mirroring option. Please give me a example.

you could use lvexend -m 1 , but, before you try to mirror a volume, make sure you've got MirrorDisk installed on your system.

"Volume and want to create a Mirror Disk ( non bootable disk)"

Ok , I am sorry , if its not vg00, avoid above procedure.

==> Pvcreate /dev/rdsk/cxtxdx
==> vgextend vgxx disk
==> lvextend -m1 lv disk
