You can fix this error in Oracle by following the below steps

Action: Check the ASM alert logs for more information. To correct disk access or failure issues either: a) restore access to the disks in the disk group and mount the disk group (via ASMCMD or SQL). or b) Issue a force mount to the disk group to offline missing disks and mount a normal or high redundancy disk group. To correct the ASM_DISKSTRING in the SPFILE and propagate the change to the GPnP profile, in sqlplus, issue the SQL command “ALTER SYSTEM SET ASM_DISKSTRING SCOPE=BOTH”
