Defining paths for drives attached only to NAS file servers

If a tape drive must be accessed only by a NAS file server and not by the IBM Storage Protect server, only a single path between the tape drive and the NAS file server is required.

Complete the following steps:

1. Obtain the SCSI element addresses, worldwide name (WWN), and serial numbers for the drive to be connected to NAS file server.
   Restriction: If the SCSI drive is connected only to a NAS file server, the element address is not automatically detected, and you must supply it. If a library has more than one drive, you must specify an element address for each drive.
   To obtain a SCSI element address, go to the following device-support websites:

   • Supported devices for AIX® and Windows
   • Supported devices for Linux®

   Element number assignment and device WWN assignments are also available from tape-library device manufacturers.
2. Create drive definitions by specifying the element addresses identified in the preceding step. Specify the element address in the ELEMENT parameter of the DEFINE DRIVE command.
   For example, to define a drive NASDRIVE1 with the element address 82 for the library NASLIB, issue the following command:

   define drive naslib nasdrive1 element=82

   Attention: For a drive connected only to the NAS file server, do not specify ASNEEDED as the value for the CLEANFREQUENCY parameter of the DEFINE DRIVE command.
3. Obtain the device name, serial number, and WWN for the drive on the NAS device.
4. Using the information that is obtained in steps 1 and 3, map the NAS device name to the element address in the drive definition in the IBM Storage Protect server.
5. Define a path between the tape drive and the NAS file server.
   For example, to define a path between a NetApp file server and a tape drive with a device name of rst01, issue the following command:

   define path nasnode1 nasdrive1 srctype=datamover desttype=drive
    library=naslib device=rst0l
