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

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.

Multiple threads are always confusing.
Hope this helps!
