: A disk group may have been forced to dismount due to lost connectivity or multiple disk failures in a failure group. Disk Header Corruption

: The metadata (headers) on one or more ASM disks may be corrupted or in a "FORMER" or "PROVISIONED" status instead of "MEMBER". Voting File Issues

: If the ASM disk group hosts the Cluster Registry (OCR) or Voting Disks, a failure can cause node evictions or cluster instability. Storage Latency/I/O Timeouts The most frequent culprit
