I know how to solve the problem.

If u have drive put back in to get ODM updated.
If not
U have to follow the following procedure.

#lqueryvg -p hdisk0 -At  Read original VGDA Area when original disk was
present hdisk1 from hdisk0.
#lspv

dd if=/dev/hdisk0 count=1 |od -x |grep 0000200<<<<This is the offset
address.

0000200 0000..............0000  this is the ID for new disk attached.

#odmget -q "name=hdisk0" CuDv >>/tmp/hdiskX.add
#odmget -a "-name=hdisk0" CuAt >>/tmp/hdiskX.add
NoW UPDATE odm TO ORIGINAL VALUE disk ID THAT U GOT WITH lqueryvg
#odmchange use this cmd.

now

reducevg vgname hdiskx
rmdev hdiskx

Look at ODM cmds very closely.If u have problem in understanding ??Good
luck.

U need to read ODM and VGDA.
