Enabling and disabling NDMP devices

Procedure

1. Navigate to Home Data Protection NDMP Device List to display the NDMP Device List page.

   

   Item/Field	Description
   EVS:Device Name	Displays the EVS or EVSs allowed to use the device, and the ID of the device. This ID is generated by the system and cannot be changed. To configure your storage management application to work with an NDMP device, in the storage management application you must specify the device name of each autochanger/tape drive you want the application to use.
   WWN Node (LUN)	Displays the WWN (World Wide Name) and LUN ID of the Fibre Channel node.
   Manufacturer (Model)	Displays the manufacturer and model of the device, if detected.
   Serial Number	Serial number of the device.
   Allow Access	Displays if access is allowed to the device. If access is not allowed, then NDMP will not attempt to use the corresponding device. NoteAn NDMP device must be assigned to an EVS before access can be allowed to the device. If access is not allowed to a device, fill the checkbox next to the device, and click allow access. To deny access to a device, fill the checkbox next to the device, and click deny access. A request to deny access will be rejected if an NDMP client has opened the device. The backup application configuration should be changed to avoid use of the device before denying access.
   Status	Current status of the selected device.

2. To enable/disable access to devices:

   • Click deny access to disable access to a device, which prevents NDMP from attempting to use the device
     NoteWhile an NDMP server has the device open, a deny access request will be rejected. Therefore, the storage management application configuration should be changed to avoid use of the device before the current configuration process.
   • Click allow access to enable access to a device, which allows NDMP to use the device.
     NoteBefore using an NDMP device, you must first allow access to it, then it must be assigned to an EVS. NDMP Devices are assigned to an EVS using the NDMP Device Access Details page described in
   • Click forget to remove the selected device from the list (only available for devices that have been disconnected from the FC).
   • Click Refresh Status on the Device List page to discover any changes in the Fibre Channel connection; that is, to find any newly attached devices and discover whether any previously discovered devices that are no longer accessible. If new devices are plugged into the Fibre Channel, use Refresh to identify them.
