Dell Storage Manager 2020 R1 Administrator's Guide

Moving a Volume Based on a Recommendation

If the volume movement recommendation was triggered by a threshold definition that monitors volume latency, automatically move the volume by creating a Live Volume or Live Migration. If the recommendation was triggered by a threshold definition that monitors Storage Center front-end IO, Storage Center controller CPU usage, or the percentage of storage used for a Storage Center, move the volume(s) manually.

1. Click the Threshold Alerts view.
2. Click the Alerts tab.
3. In the Current Threshold Alerts pane, locate the threshold alert that contains the volume movement recommendation. Alerts that contain recommendations display Yes in the Recommend column.
4. Right-click the threshold alert, then select Recommend Storage Center. The Recommend Storage Center dialog box opens.
   • If the recommendation was triggered by a threshold definition that monitors volume latency, the dialog box displays a Storage Center recommendation and allows you to move the volume by creating a Live Volume or Live Migration. If Dell Storage Manager identified a possible reason for the increased volume latency, the reason is displayed in the Recommend Reason field
   • If the recommendation was triggered by a threshold definition that monitors Storage Center front-end IO, Storage Center controller CPU usage, or the percentage of storage used for a Storage Center, the dialog box displays a recommended Storage Center without suggesting specific volumes to move.

     To act on the recommendation, record the Storage Center names displayed in the Current Storage Center and Recommended Storage Center fields.
