===> i will do the following :

1- dettach physical volume from vg
pvchange -a n /dev/dsk/c3t2d0

2- hot swap the disk

3- create a description file
#cat >> /tmp/idf << EOF
3
EFI 500MB
HPUX 100%
HPSP 400MB
EOF

4 use idisk to setup partitioning

idisk -wf /tmp/idf /dev/rdsk/c3t2d0

5- use mkboot to format newly efi partition

mkboot -e -l /dev/dsk/c3t2d0

6- change auto file contents

#cat >> /tmp/auto << EOF
boot vmunix -lq
EOF

#efi_cp -d /dev/rdsk/c3t2d0s1 /tmp/auto /efi/hpux/auto

7- restore LVM reserved areas

vgcfgrestore -n vg00 /dev/rdsk/c3t2d0s2

8- rettach the new disk

pvchange -a y /dev/dsk/c3t2d0s2

9- reactivate vg to attach pv

vgchange -a y vg00

10- force sync vg

vgsync vg00

lvlnboot -r
lvlnboot -v

The steps look fine.. just for step#1, you need to specify /dev/dsk/c3t2d0s2 instead of /dev/dsk/c3t2d0
