Yes. You have to use:
vgremove vg01
pvcreate /dev/
vgcreate vg01 /dev/
lvcreate -L
mkfs -t ext3 /dev/vg01/
tune2fs -i 0 -m 0 -c0 /dev/vg01/
mount /path/mount/point

Does it have a mirror? If so, remove bad disk and put new disk. issue vgcfgrestore command on to new disk.
If vg01 is completly destroyed then use procedure in the 1st reply.

Re: how to transfer physical volume infomation on to new disk
VG01 is not dead, but I/O is giving error on vg01 which i found from syslog file.
Once i shutdown then it running fine for 2-3 days. I think may be some sectors were corrupted in particular LVM hence it want able to right on it and giving I/O error. Is there any way to find out which sector are bad and how to repair it.
Thanks

Re: how to transfer physical volume infomation on to new disk
how mandy PVs a member of the VG? Maybe it's only a faulty member of the VG. If you know which member disk a faulty, try pvmove. With pvmove you can move PEs to another PV. If only one disk is member of the VG, you can add a second PV and then use pvmove to move the PEs from the faulty PV.
Best regards,
Patrick
