asmcmd afd_scan finding some of the disks, but not all when using multiple paths

in Storage Management (ASM ACFS DNFS ODM) (MOSC) 3 commentsAnswered ✓

19.26.0.0c on RHEL 8 with Grid Infrastructure
Using a mix of local and multipath devices for two separate disk groups:
Diskgroup DATA: /dev/sdb
Diskgroup BACKUP: /dev/mapper/mpatha - /dev/mapper/mpathad

/etc/oracleafd.conf:
afd_diskstring='/dev/sd*,/dev/mapper/mpath*'
afd_dev_count=31

After partitioning all the devices and labelling them without any problems, if I reboot the server, the /dev/sdb1 shows up and some of the /dev/mapper/mpath devices show up, but not all after the reboot.

If I run "asmcmd afd_scan", nothing changes

If i run "asmcmd afd_scan '/dev/mapper/mpath*'", all the missing devices are found

Howdy, Stranger!
