Some LUNs were removed from the server and now LVM commands give error messages

Check with the command dmsetup the device that needs to be removed and then remove it. I do it from bottom to top

root@linux:~# dmsetup ls | grep lv_sapmnt_exe
vgHP0ascs-lv_sapmnt_exe (253:21)
root@linux:~# dmsetup remove vgHP0ascs-lv_sapmnt_exe

root@linux:~# dmsetup ls | grep lv_sapmnt
vgHP0ascs-lv_sapmnt_profile (253:18)
vgHP0ascs-lv_sapmnt_global (253:17)
vgHP0ascs-lv_sapmnt (253:20)
root@linux:~# dmsetup remove vgHP0ascs-lv_sapmnt

root@linux:~# dmsetup ls | grep lv_usrsapHP0
vgHP0ascs-lv_usrsapHP0 (253:19)
root@linux:~# dmsetup remove vgHP0ascs-lv_usrsapHP0

root@linux:~# dmsetup ls | grep lv_sapmnt_profile
vgHP0ascs-lv_sapmnt_profile (253:18)
root@linux:~# dmsetup remove vgHP0ascs-lv_sapmnt_profile

root@linux:~# dmsetup ls | grep lv_sapmnt_global
vgHP0ascs-lv_sapmnt_global (253:17)
root@linux:~# dmsetup remove vgHP0ascs-lv_sapmnt_global

root@linux:~# dmsetup ls | grep lv_NOVELL_RemoteLoader
vgHP0ascs-lv_NOVELL_RemoteLoader (253:16)
root@linux:~# dmsetup remove vgHP0ascs-lv_NOVELL_RemoteLoader

root@linux:~# dmsetup ls | grep lv_ASCS
vgHP0ascs-lv_ASCS (253:15)
root@linux:~# dmsetup remove vgHP0ascs-lv_ASCS

root@linux:~# dmsetup ls | grep 350002ac4f691374a
350002ac4f691374a (253:14)
root@linux:~# dmsetup remove 350002ac4f691374a

Then after issuing pvs, it won’t show error messages anymore
