Note:  ProtecTIER GA Version 3.4 was released with only the Virtual Tape Library (VTL)  interface support. File System Interface (FSI) support was added to ProtecTIER PGA 3.4  Version. For details, see the announcement letter: http://www.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_ca/6/872/ENUSA P16-0076/index.html&lang=en&request_locale=en Before you set up the new IBM Spectrum Protect device classes for the FSI export, disable  the server option directly. On a Linux system, configure the value for the  DIRECTIO  parameter,  as shown in Example 13-10, in the  dsmserv.opt  file. IBM Spectrum Protect does try to use  direct I/O to files on NFS shares when it is using  dataformat=native  (the default) on the  storage pools. To set backup and restore on IBM Spectrum Protect, start the IBM Spectrum Protect server  by running the following command on the UNIX host: /opt/tivoli/tsm/server/bin/dsmserv Note:  This operation can be executed by using the Operations Center. The  dsmserv  command starts the IBM Spectrum Protect server. After the server is running,  complete the following steps from the server in preparation for performing an IBM Spectrum  Protect backup: Therefore, two dedicated examples are shown for each operating system type. To create  the device class, run the command that is shown in Example 13-11 from the administrative  command line of the IBM Spectrum Protect server. Alternatively if you configure a IBM Spectrum Protect server on Windows with a  ProtecTIER CIFS share, run the command that is shown in Example 13-12. Chapter 13.

With ProtecTIER FSI, create sequential I/O device classes when you store the IBM  Spectrum Protect volumes in an FSI share. A random file device class is not supported.  The definition of the device class is the only step that differs between a Windows and  UNIX IBM Spectrum Protect configuration, because it contains the operating  system-specific file system notations.  13.3.1 Setting up backup and restore on IBM Spectrum Protect
