This should have removed the <name>p1 partition map previously created by kpartx -a.
server1:/# kpartx -d /dev/mapper/d-pdc.oa.c1
The kpartx command expects the base device as its argument (as you gave in the previous command). This should be "/dev/mapper/d-pdc.oa.c" (the '1' is the partition index and the 'p' is the separator).
failed to stat() /dev/mapper/d-pdc.oa.c1
The partition map has a 'p' separator - d-pdc.oa.cp1 - the correct command is:
kpartx -d /dev/mapper/d-pdc.oa.c
server1:/# lvs | grep oa pdc.oa.c d -wi-ao 37.00G
The LV is still showing as active and open here. You should be able to remove it with lvremove d/pdc.oa.c or shut it down with vgchange/lvchange after correctly removing the kpartx mapping.
If it still shows as open you may want to look at the output of "dmsetup ls --tree" to see if there are other device-mapper devices using it and make sure that it's not mounted anywhere.
