Error Code [13:245] and [30:378]

Hi ​@gogi100 ,
 

Auxiliary copy jobs are failing with the error "Media read operation failure" and "Operating System could not find the path specified", pointing to a  disk media path. Although the storage share is accessible via Windows Explorer and CMD, Commvault is unable to read from the specified path during job execution.

Could you please check the below and let us know. Thank You!

1. Verify Disk Library Path Configuration: Ensure that the mount path \\192.168.170.100\AMS_Backup\Commvault\9ITOLX_09.06.2022_10.40\CV_MAGNETIC\V_10282 is correctly defined in the disk library settings. Confirm that the correct MediaAgent is assigned and has access to the mount path.

2. Check Mount Path Status in CommCell Console: Go to Storage Resources > Libraries. Right-click the relevant disk library > Properties > Mount Paths tab.

Make sure the mount path is Online. If not, try to re-enable or re-add it.

3. Validate Permissions: Confirm that the MediaAgent service account has full read/write and NTFS permissions on the shared folder. Ensure any credentials used in Commvault for the UNC path are correct and active.

4. Confirm Path Consistency: If storage disks or paths changed, Commvault might be referencing an outdated path. Double-check that the path configured in Commvault exactly matches the restored structure on the storage.

5. Restart Commvault Services on MediaAgent: Restarting services on the MediaAgent can help resolve mount path state inconsistencies.

6. Review Logs and Event Viewer: Examine Windows Event Viewer for any system or disk errors. Review Commvault logs like CVMA.log and cvjobreplicatorods.log on the MediaAgent for deeper insights.

in the meantime I found that there is a problem between my tape drive and the storage library. on the server where the media agent is installed through which my tape drive accesses the storage \\192.168.170.100\AMS_Backup\Commvault\9ITOLX_09.06.2022_10.40\CV_MAGNETIC\ I can access it from windows explorer. I have a problem with the storage policy. I did Run Data Verification on my Hyper-V-sharepoint and SQL-server-plan. I ran Run Auxiliary Copy, I chose secondary copy and both copies went through but I got a message on one of the policies

I checked jobs 535761,535764,536839,536840,538304 in Job controller and they all completed successfully

I don't know what else to do.

now, in job controller i receive

my logs for this job, i attached on message

Hi ​@gogi100 ,
 

Below message indicates that while the backup jobs completed successfully on the source copy, they failed data verification. Because of this, the auxiliary copy process skipped these jobs and did not copy them to the secondary (tape) copy.

"Some jobs [535761, 535764, 536839, 536840, 538304] have been skipped on copy [SQL-server-plan/SQL_On_Tape] since data verification failed on these jobs on source copy."

Backup jobs may appear as “Completed”, but if the backup data becomes unreadable, missing, or corrupted, Commvault's data verification process will flag them as failed.

Jobs that fail verification are marked as "Bad" and are excluded from auxiliary copy to prevent copying incomplete or potentially corrupted data — this is an intentional safeguard to maintain data integrity.

- Check Data Verification Status : In commcell console -> Navigate to the storage policy copy for SQL-server-plan -> Locate the affected jobs and check the Data Verification Status column.
Jobs with a status of “Failed” are not eligible for auxiliary copy.

-  Identify the Cause of Failure : Common causes include Missing or deleted backup files, Inaccessible or offline mount paths, Disk issues or corruption, Permission errors

- Review the Job History or the Data Verification Job Summary Report for detailed error messages - Data Verification Job Summary Report Overview
- If the mount path or disk is now available and healthy, you may attempt to re-run data verification for these jobs on the Source copy from Storage Policy → Copy → View Jobs → Run Data Verification.
- If the verification still fails, the backup data is likely no longer usable.
- Run New Full Backups for the affected clients or subclients. to ensure data availability for future auxiliary copies.
- These new jobs will serve as valid recovery points for secondary copies.

Please review the Auxiliary Copy Troubleshooting. If still issue persist, would recommend opening a support case to investigate further. Thank You!!
