ORA-15080 on ASM rebalance operation

Noticed an error ORA-59035 on re-balance operation and ASM re-balance operation got stuck

Solution

Work around is to disable the hard check on ASM instance and start re-balance operation and post re-balance set back hard check to true

alter diskgroup RECOC1 set attribute 'hard_check.enabled' = 'FALSE';

ALTER DISKGROUP RECOC1 REBALANCE POWER 32;

After rebalance completion re-enable the hard check

alter diskgroup RECOC1 set attribute 'hard_check.enabled' = 'TRUE';
