Thanks!

It works! I did as the following:
"""
sle15-c1-n1:~ # vgs
Reading VG vg1 without a lock.
VG #PV #LV #SN Attr VSize VFree
vg1 1 1 0 wz--ns 19.97g 18.72g
sle15-c1-n1:~ # vgchange --lock-type none vg1
Cannot access VG vg1 due to failed lock.
sle15-c1-n1:~ # vgchange --lock-type none --lockopt force vg1
Forcibly change VG lock type to none? [y/n]: y
Volume group "vg1" successfully changed
sle15-c1-n1:~ # vgchange --lock-type dlm vg1
Volume group "vg1" successfully changed
sle15-c1-n1:~ # vgs

Thanks,
