Defining paths for drives attached to a NAS file server and to the IBM Storage Protect server

If a tape drive must be accessed by a network-attached storage (NAS) file server and the IBM Storage Protect server, you must create two paths. One path exists between the tape drive and the NAS file server. The other path exists between the tape drive and the IBM Storage Protect server.

Complete the following steps:

1. If the drive is not defined for the IBM Storage Protect server, create the drive definition.
   For example, to define a drive NASDRIVE1 for a library NASLIB, issue the following command:

   define drive naslib nasdrive1 element=autodetect

   Remember: If the drive is attached to the IBM Storage Protect server, the element address is automatically detected.
2. Map the NAS drive name to the corresponding drive definition on the IBM Storage Protect server:
   • On the IBM Storage Protect server, issue the QUERY DRIVE FORMAT=DETAILED command to obtain the worldwide name (WWN) and serial number for the drive that will be connected to the NAS file server.
   • On the NAS device, obtain the tape device name, serial number, and WWN for the drive.
   If the WWN or serial number matches, a drive on a NAS file server is the same as the drive on the IBM Storage Protect server.
3. Using the drive name, define a path to the drive from the NAS file server and a path to the drive from the IBM Storage Protect server.
   • For example, to define a path between a tape drive with a device name of rst01 and a NetApp file server, issue the following command:

     define path nasnode1 nasdrive1 srctype=datamover desttype=drive
       library=naslib device=rst01

   • To define a path between the tape drive and the IBM Storage Protect server, issue the following command:
     

     define path server1 nasdrive1 srctype=server desttype=drive
      library=naslib device=/dev/rmt0

     

     define path server1 nasdrive1 srctype=server desttype=drive
      library=naslib device=/dev/tsmscsi/mt0

     

     define path server1 nasdrive1 srctype=server desttype=drive
      library=naslib device=mt3.0.0.2
