AFD managed devices does not match

ASMCMD-9512: failed to update AFD disk string in Oracle Local Repository.

$ asmcmd afd_dsset '/dev/xvdd*'
AFD managed disk '/dev/xvdc1' is not part of '/dev/xvdd*'
AFD managed devices does not match '/dev/xvdd*'
ASMCMD-9512: failed to update AFD disk string in Oracle Local Repository.

Cause
Trying to overwrite ASM_DISKSTRING parameter with the value which does not discovers ASM known disks on OS

Solution
Modify the command to include all ASM known disk strings. Find out the current ASM_DISKSTRING parameter value and include it in your command while overwriting the ASM_DISKSTRING value using afd_dsset command

$ asmcmd afd_dsget
AFD discovery string: /dev/xvc

$ asmcmd afd_dsset '/dev/xvc*','/dev/xvdd*'

$asmcmd afd_dsget
AFD discovery string: /dev/xvc,/dev/xvdd*
