A disk group can become inconsistent if a disk fails, or if the ASM metadata is corrupted. For example, the message may appear after an abrupt system outage, a failed disk rebalance operation, or a hardware error that left a disk in a FORCING state. The ALTER DISKGROUP ... CHECK command often reveals “mismatched extent maps” or “stale partner relationships.”
