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:

## 13.3.1 Setting up backup and restore on IBM Spectrum Protect 

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. 

DIRECTIO NO 

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: 

1. 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. 

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. 

DEFine DEVclass PT1_fsi_devclass DEVType=FILE MOUNTLimit=192 MAXCAPacity=8G DIRectory=/mnt/puck_tsm2_nfs1,/mnt/puck_tsm2_nfs2 

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. 

DEFine DEVclass PT1_fsi_devclass DEVType=FILE MOUNTLimit=192 MAXCAPacity=8G DIRectory=\\FSI_IP_alias\share1
