PPDM Unity-sikkerhedskopieringer mislykkes, ABNA0026 kan ikke fuldføre SNAPSHOT_AND_SLICE-handling, overdreven snapshots

Unity NAS-sikkerhedskopieringer mislykkes med følgende fejl:

ABNA0026: Unable to complete the SNAPSHOT_AND_SLICE operation because the NAS Agent cannot create the snapshot for the share path unity_data01_smb.

Creation of the snapshot for the asset cannot be completed because an error occurred.

 To troubleshoot this issue: 
1) Check and address the vendor specific message for more details. 
2) Check the array to ensure that no errors occurred during snapshot creation. 
3) Check if the snapshot capability license is available and enabled. 
4) Manually clean up the snapshot if the snapshot capacity for the asset/file system has been exceeded. 
5) Make sure that backup user has all required privileges. 
6) Check if the filesystem has requisite available storage. 
7) Verify that the array can be reached over the proxy network. 
8) Check for the export path length. The characters that are allowed for path length should be within 255 characters.

Og for den detaljerede fejlmeddelelse:

NAS vProxy Engine Protection_ENGINE_FQDN is unable to perform SnapshotAndSlice operation for nasShare unity_data01_smb.

 NAS agent error code 'ABNA0026'. Snapshot creation failed for file system 'unity_data01_smb'. Reason: Rest response code 409 for url : https://UNITY_IP/api/types/snap/instances, error Code : 1903001780, error message : Unable to create the snapshot because the maximum number of snapshots already exists for the file system. (Error Code:0x716d80b4)

Hvis du forsøger at tage et manuelt snapshot på Unity-filsystemerne, vises denne fejlmeddelelse:

Unable to create the snapshot because the maximum number of snapshots already exists for the file system. (Error Code: 0x716d80b4)

Dette sker, fordi der er for mange snapshots til de samme filsystemer.

Fra Unity Unisphere, i Systemsoftware> og licenser >Systembegrænsninger, er der systemsnapshotbegrænsningen:

Dette viser snapshots-begrænsningen.

Du kan løse dette problem ved at reducere antallet af snapshots fra filsystemerne.

Hvis dette ikke kan gøres, foreslås det at åbne en serviceanmodning til Dell Unity Support for at diskutere og forstå, hvorfor mange snapshots præsenteres.
