# View device group details

A device group is a user-defined group that consists of devices that belong to a locally attached storage system. Control operations can be performed on the group as a whole, or on the individual device pairs in the group. By default, a device can belong to more than one device group.

## Steps

1. Select the storage system.
2. Select Data Protection > Device Groups.
3. Click the Device Groups tab to open the Device Group list view.
4. Select the device group and click to open the Details view.

   The following properties display, depending on the operating environment:

   - Name—User-defined device group name
   - Application ID—Indicates which application created the device group.
   - Group Valid—Indicates whether the device group is valid.
   - Device Group Create Time—Time the device group was created.
   - Device Group Modify Time—Time the device group was modified.
   - Array ID—Storage system serial number ID
   - Number of Volumes—Number of volumes
   - Number of Associate Gatekeepers—Number of gatekeeper devices in the device group
   - Number of STD Volumes in Group—Number of standard devices in the device group
   - Number of Locally-Associated BCVs—Number of local BCV devices associated with the device group
   - Number of Locally-Associated VDEVs—Number of virtual devices associated with the device group
   - Number of Locally-Associated TGTs—Number of local target volumes associated with the device group
   - Number of Remotely-Associated BCVs (STD SRDF)—Number of remote BCV devices associated with the device group
   - Number of Remotely-Associated BCVs (BCV SRDF)—Number of BCV devices which are associated with the device group, to be paired with remotely attached BCV devices
   - Number of Remotely-Associated RBCVs (RBCV SRDF)—Number of remote BCV devices associated with the device group
   - Number of Remotely-Associated VDEVs—Number of remote VDEV devices associated with the device group
   - Number of Remotely-Associated TGTs—Number of remote target devices associated with the device group
   - Number of Hop2 BCVs (Remotely-associated Hop2 BCV)—Number of BCVs on the second hop of the Cascaded SRDF configuration associated with the device group
   - Number of Hop2 VDEVs (Remotely-associated Hop2 VDEV)—Number of virtual devices on the second hop of the Cascaded SRDF configuration associated with the device group
   - Number of Hop2 TGTs (Remotely-associated Hop2 TGT)—Number of target devices on the second hop of the Cascaded SRDF configuration associated with the device group
   - Number of Composite Groups—Number of composite groups
   - Pacing Capable—Indicates if the device group allows write pacing capability.
   - Group-level Pacing State—Indicates if the device group is write pacing enabled or disabled.
   - Volume-level Pacing State—Indicates if the volumes in the device group are write pacing enabled or disabled.
   - Configured Group-level Exempt State—Indicates if group-level write pacing exemption capability is enabled or disabled.
   - Effective Group-level Exempt State—Indicates if effective group-level write pacing exemption capability is enabled or disabled.
   - Group Write Pacing Exempt Volumes—Indicates if the volumes in the device group have write pacing exemption capability enabled or disabled.

   Links are provided to views for objects that are contained in or associated with the device group. Each group link is followed the name of the group, or by a number, indicating the number of objects in the corresponding view. For example, clicking the number next to Number of Volumes opens the view listing the volumes that are contained in the device group.
