After SGLX install and LVM.conf settings, RHEL never booted.

I'm beginner of serviceguard on linux and I got LVM error while creationg cluster.
Could you give me some advice on what I should do with this isssue?

problem
After SGLX install and LVM.conf settings, RHEL never booted.
OS showed only / and swap partitions, failed e2fsck on the other OS internal partition(/var, /home...). I did e2fsck to the other partitions, but failed.
I could not find /var or /home device mapper file in /dev/mapper.

Following steps are my operations.

1. 2 nodes on Vmware Esxi, OS is RHEL6.9, SG is 12.20.00.
2 shared disks for data created into datastore (vmdk file)
1 disk for lock lun also created into same datastore (vmdk file)
2. I installed device-mapper-multipath.rpm
mpathconf --enable --user_friendly_names y
  /etc/init.d/multipathd start
-> RHEL detected 3disks and made
/etc/multipath/bindings
3.I created device-mappers following command.
kpartx -v -a /dev/sdX for 3 external disks
4.created PV for 1 disks
pvcreate /dev/mapper/mpathXp1 -> for data
pvcreate /dev/sdd1 -> for lock
5.created VG for 2 data disks
6.SGLX install
7.lvm configuration
added 2 line into /etc/lvm.conf
volume_list = [ "vg1", "vg2" ]
tags { hosttags = 1 }
8.OS reboot
-> OS could not recognize partitions except / and swap, so never booted.

My LVM operations destroyed device mapper data?
