Fix the underlying hardware, multipathing (MADP, PowerPath), or permission issues at the OS level. Once the OS sees the disk again, online it in ASM: ALTER DISKGROUP ONLINE DISK ; Use code with caution. Scenario B: Disk Space Exhaustion (Corrupted or Full)

Fix: Clear out old UCS files or decrease the log storage period in your logging profile. Use df -h in the CLI to verify space. 3. ASM Policy Synchronization

If the alert persists in Enterprise Manager or Oracle Cloud Infrastructure (OCI) console dashboards despite resolving the root cause, manually clear or acknowledge the alert tracking history to reset the baseline monitor.

While less frequent, the term appears in other specialized software. For instance, the product suite uses an "ASMInst agent" that may have health check monitoring limitations, resulting in failure messages. In such cases, the solution is to adjust the agent's configuration.

When this alert surfaces in your alert log or monitoring dashboard (like Enterprise Manager), it means ASM has identified a specific issue that could potentially impact the availability or performance of your storage layer. Use df -h in the CLI to verify space

SELECT group_number, disk_number, mode_status, header_status, name FROM v$asm_disk; Use code with caution. Look for disks with a MODE_STATUS of OFFLINE .

If you're a database administrator or a system administrator working with Oracle databases, you're likely familiar with the Automatic Storage Management (ASM) system.

Oracle provides the asmcmd utility to query the health status of disk groups directly. Log in as the Grid Infrastructure OS user (typically grid ) and execute: asmcmd chkdg -g Use code with caution.

⚠️ : While effective for many metadata and consistency issues, this command may not resolve all types of failures. Always review the report from Step 3 to ensure the repair is appropriate. Backing up critical data before running a repair operation is a sound practice.

SUCCESS: ALTER DISKGROUP... followed by immediate GMON dumping or failure notes.
