asmfd candidate disks not being seen by the 19c GI installer

I am installing Oracle 19c (19.3.0.0) on RHEL 7.5.  I used asmfd to label my disks ($ORACLE_HOME/bin/asmcmd afd_label DATA01 /dev/sdb --init).  When running the installer I used the discovery path /dev/sd*, but because the disks are owned by root:disk (and permissions cannot be changed), none of the /dev/sd* disks are being discovered.  I unlabled DATA01 ($ORACLE_HOME/bin/asmcmd afd_unlabel /dev/sdb --init) and relabeled using /dev/mapper.  This changed the ownership of /dev/dm-37 to root:oinstall and it can be seen via OUI when using the discovery path of /dev/dm*, however, as the /dev/mapper and /dev/dem sym link is not identical between my 2 nodes,
