EVA6100 - Drive device file name changed

Its HP-UX 11.31. Server's hba card get faulty. after replacing it, the server has detected the storage vdisks as different device file name, resulting in failure of vg activation.

 

Older device file names are /dev/dsk/c4t0d5 and /dev/dsk/c9t0d4, which are physically no more.

New device file names are /dev/dsk/c9t0d2 and /dev/dsk/c9t0d3

 

Below are the steps/information which I have taken collected. Now need to recover my VG.

 

# vgexport -p -s -m /tmp/VG99.map /dev/VG99

# vgexport /dev/VG99

# mkdir -m 755 /dev/VG99

# mknod /dev/VG99/group c 64 0x010000

# vgimport -s -m /tmp/VG99.map /dev/VG99
Couldn't access the list of physical volumes for volume group "/dev/VG99".

 

VGSCAN:
vgscan: Couldn't access the list of physical volumes for volume group "/dev/VG99".
Physical Volume "/dev/dsk/c9t0d2" is not part of a Volume Group
Physical Volume "/dev/dsk/c9t0d3" is not part of a Volume Group

 

# strings /etc/lvmconf/VG99.conf
CONFIG01
/dev/VG99
/dev/rdsk/c4t0d5
/dev/rdsk/c9t0d4
LVMREC01
LVMREC01
VGDA0001
VGSA0001P
#

 

Can we change the LUNs from HP-UX, because from storage the vdisk is same as before?

Zoning and presentation is OK.
Also checked the new disk with diskinfo and it is showing the correct values.
