Parameters

data_mover_name (Required)
Specifies the name of the data mover.

HLAddress
Specifies either the new numerical IP address or the new domain name, which is used to access the NAS file server. This parameter is optional.

LLAddress
Specifies the new TCP port number to access the NAS file server for Network Data Management Protocol (NDMP) sessions. This parameter is optional.

WWN
Specifies the Fibre Channel world wide name of a new data mover. This parameter is optional. This should only be specified if the data mover became defective and was replaced with another data mover. The fibre channel world wide name can be updated to preserve the data mover and associated path definitions.

SERial
Serial number of new data mover. This parameter is optional. This should only be specified if the data mover became defective and was replaced with another data mover. The serial number can be updated to preserve the data mover and associated path definitions.

USERid
Specifies the user ID for a user that is authorized to initiate an NDMP session with the NAS file server. For example, enter the administrative ID for a Network Appliance file server. This parameter is optional.

PASsword
Specifies the new password for the user ID to log onto the NAS file server. This parameter is optional.

COPYThreads
Specifies the number of concurrent copy operations that the data mover can support. Please refer to the documentation for your device to obtain the maximum value. The number must be greater than 0.
Note:
This parameter is used to govern how many copy commands can run concurrently on a server at any one time. If other programs or servers will be using the extended copy capabilities of the data mover device, you may want to specify fewer than the maximum number of concurrent copy commands supported by the device for this parameter.

ONLine
Specifies whether the data mover is available for use. This parameter is optional.

Yes
Specifies that the data mover is available for use.

No
Specifies that the data mover is not available for use.

Attention: If a library is controlled using a path from a data mover to the library, and the data mover is offline, the server will not be able to access the library. If the server is halted and restarted while the data mover is offline, the library will not be initialized.

Note:
When the hardware is being maintained you can use the UPDATE DATAMOVER command to set the data mover off-line.
