Dell recommends scheduling resource-intensive operations during specific time periods when no other system operations are being performed. This approach is called windowing, which requires scheduling a specific block of time (or “window”), each with a set starting and stopping point so that you can perform data ingests, replication, or space reclamation operations without interfering with the running of any other operation.
NOTE: The Cleaner Schedule page displays the current DR Series system time zone and current timestamp (using this format: US/Pacific, Fri Nov 2 15:15:10 2012). |
To schedule Cleaner operations on your system, complete the following:
1. |
2. |
3. |
Select (or modify) the Start Time and Stop Time setpoint values using the Hour and Minutes pull-down lists to create a Cleaner schedule. |
NOTE: You must set a corresponding Stop Time for every Start Time set in each Cleaner schedule you create. The DR Series system will not support any Cleaner schedule that does not contain a Start Time/Stop Time pair of setpoints (daily or weekly). |
4. |
Click Set Schedule for the system to accept your Cleaner schedule (or click Cancel to display the Cleaner Schedule page). |
NOTE: To reset all of the values in the current Cleaner schedule, click Reset in the Set Cleaner Schedule dialog. To selectively modify values in the current schedule, make your changes to the corresponding hours and minutes pull-down lists to represent the Start Time and Stop Time you wish to set, and click Set Schedule. |
The current Cleaner Status is represented in the Dashboard page in the System Information pane as one of the three following states:
• |
Pending—displayed when there is any scheduled window set and the current time is outside the scheduled window for the Cleaner operation. |
• |
Running—displayed when the Cleaner operation is running during a scheduled window. |
• |
Idle—displayed only if there is no Cleaner operation running during a scheduled window. |
NOTE: For more information about using the system cleaner, refer to the DR Series System Cleaner Best Practices white paper for your specific DR Series system at: dell.com/support/manuals. |
To display additional Cleaner statistics, you can use the DR Series system CLI stats --cleaner command to show the following categories of Cleaner statistics:
