ALERT

Description

This message occurs when file system analytics fails to turn off. This can cause incorrect file system analytics results.

Corrective Action

Use the "volume show -dsid <dsid>" command to find the volume on which file system analytics failed to turn off, and then use the "volume analytics off" command to attempt to turn off file system analytics. If problems persist or further assistance is needed, contact NetApp technical support.

Syslog Message

File system analytics failed to turn off on the volume with DSID "%lu". Error: %d. Context: %s.

Severity

ALERT

Description

This message occurs when a volume fails to recover the File System Analytics state after failing to start the initialization scanner. As a consequence, File System Analytics information might be unavailable or might not accurately reflect the volume's content.

Corrective Action

Use the "volume analytics off" command to disable File System Analytics on the volume, and then use the "volume analytics on" command to enable File System Analytics. If problems persist or further assistance is needed, contact NetApp technical support.

Syslog Message
