PRTG Manual: Dell PowerVault MDi Logical Disk Sensor
The Dell PowerVault MDi Logical Disk sensor monitors a virtual disk on a Dell PowerVault system.
This sensor supports Dell PowerVault MD3000i, MD3420, MD3620i, MD3000f, MD3620f, or MD3820i, and might support other models.
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

- This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe.
- This sensor requires Dell Modular Disk Storage Manager on the probe system.
- This sensor requires the IP address of the storage area network (SAN) in the settings of the parent device.
- This sensor supports Dell PowerVault MD3000i, MD3420, MD3620i, MD3000f, MD3620f, or MD3820i, and might support other models.
- This sensor only supports IPv4.
You cannot add this sensor to the hosted probe of a PRTG Hosted Monitor instance. If you want to use this sensor, add it to a remote probe device.
Requirement |
Description |
---|---|
This sensor requires the installation of the Dell Modular Disk Storage Manager program. You must install it on the probe system (on every cluster node, if on a cluster probe). For details about setup, see section More below. Create this sensor on a device that has the IP address of the SAN configured in the IP Address/DNS Name field of the sensor settings. For more information, see the Knowledge Base: Where do I find the Dell PowerVault Modular Disk Storage Manager for use with my MDi SAN? |
Setting |
Description |
---|---|
Sensor Name |
Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets. If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include? |
Parent Tags |
The tags that the sensor inherits from its parent device, parent group, and parent probe. This setting is for your information only. You cannot change it. |
Tags |
Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited. It is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>). For performance reasons, it can take some minutes until you can filter for new tags that you added. The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
|
Priority |
Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority () to the highest priority (). |
Setting |
Description |
---|---|
Virtual Disk |
The name of the virtual disk that this sensor monitors. |
Result Handling |
Define what PRTG does with the sensor result:
In a cluster, PRTG stores the result in the PRTG data directory of the master node. |

Primary Channel |
Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed below the sensor's name. The available options depend on what channels are available for this sensor. You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab. |
Graph Type |
Define how different channels are shown for this sensor:
|
Stack Unit |
This setting is only visible if you select Stack channels on top of each other above. Select a unit from the list. All channels with this unit are stacked on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so. |
By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Inheritance of Settings.
For more information, see section Root Group Settings, section Scanning Interval.
Schedules, Dependencies, and Maintenance Window
You cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.
For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window (default).
For more information, see section Root Group Settings, section Access Rights.
Which channel units are available depends on the sensor type and the available parameters. If no configurable channels are available, this field shows No configurable channels.
For more information, see section Root Group Settings, section Channel Unit Configuration.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
