Removing a disk-based storage device

You can use the following procedure to remove a disk-based storage device that is no longer required.

When you remove a device, the backups stored on the device are not deleted. You can add the device to the same or different NetVault Server to use the backups. If you add the device to a different server, you must scan the device to use the backups stored on it.

To remove a disk-based storage device:
1
In the Navigation pane, click Manage Devices.
2
In the list of devices, locate the device and click the corresponding Manage Device icon .
3
On the RAS Device Management, click Remove. In the confirmation dialog box, click Remove again.
4
If NetVault fails to remove the device, select the Force Removal check box in the confirmation dialog, and click Remove.
 
* 
NOTE: You can use the Force Removal option to remove a device that is not in use. However, the device may still try to communicate with the NetVault Server.

Viewing disk device details

The Manage Devices page shows all the devices that have been added to the NetVault Server. The current status of the devices is depicted using the following light icons.

 
Table 90. Device status icons
Status Indicator
Description

Green light

Device is online and available for use.

Yellow light

Device is in use. NetVault is able to detect the device, but unable to access it for backup or restore jobs.

Red light

Device is currently offline. NetVault can detect the device but it cannot be accessed for backup or restore jobs.

Red cross

Device is unavailable (the SCSI cable is disconnected, the device is removed, or any other reason). NetVault cannot detect the device.

To view disk device details:
1
In the Navigation pane, click Manage Devices. Select Tree View.
2
To view the details of a particular device, click the corresponding device and then click Status.
3
The device status dialog box includes the following tabs.
DR Series systems and Data Domain systems:
•
Activity
•
Name: The name of the storage device. The name is derived from the container name and the DNS name or IP address of the device.
•
Status: The status of the device. AVAILABLE specifies that the device is available for backups and restores, while OFFLINE specifies that the device is unavailable and cannot be used for backups or restores.
•
Stream count: The number of elements or NetVault segments currently being sent to the DR Series system or Data Domain system.
•
Claims on device from this server: The number of Media Manager batch tasks using the DR Series system or Data Domain system. A batch task is associated with each backup, restore, scan, or load index stream connection to the device. A single job can have more than one claim on a device. For example, a single multi-channel Data Copy or Exchange backup can make multiple simultaneous claims on a device.
•
Send (MB/sec): The total megabytes per second (MBps) across all streams being sent out from the DR Series system or Data Domain system to NetVault (that is, when an NetVault restore job is being performed).
•
Receive (MB/sec): The total MBps across all streams being sent to the DR Series system (that is, when a NetVault backup job is being performed).
 
* 
NOTE: When you add a DR Series system to multiple NetVault Servers, the Activity tab will shows the accumulated transfer statistics for all servers.
•
Device
•
Name: The name of the storage device. The name is derived from the container name and the DNS name or IP address of the device.
•
Details: The DR OS version and the Client RDA API version.
- OR-

NetVault SmartDisk devices:
•
Activity
•
Name: The name of the storage device. The name is derived from the host name and IP address of the device.
•
Status: The status of the device. AVAILABLE specifies that the device is available for backups and restores, while OFFLINE specifies that the device is unavailable and cannot be used for backups or restores.
•
Stream count: The number of elements or NetVault segments currently being streamed to the NetVault SmartDisk.
•
Claims on device from this server: The number of Media Manager batch tasks using the NetVault SmartDisk device. A batch task is associated with each backup, restore, scan, or load index stream connection to the device. A single job can have more than one claim on a device. For example, a single multi-channel Data Copy or Exchange backup can make multiple simultaneous claims on a device.
•
Send (MB/sec): The total megabytes per second (MBps) across all streams being sent out from the NetVault SmartDisk device to NetVault (that is, when an NetVault restore job is being performed).
•

•
NONE: The status is unknown.
•
Staging space available: The total space available to the NetVault SmartDisk device across all configured Storage Volumes that do not deny Staging. It does not include the Garbage Collection Reserve or LRT.
