IBM Spectrum Protect options files
Content Platform Engine creates or updates the IBM Spectrum Protect options files whenever a fixed content device is created or altered. The shared options files define connection information for one or more IBM Spectrum Protect servers and must be accessible to every Content Platform Engine instance in the domain.
The shared IBM Spectrum Protect options files are in the directory that is referenced by the Configuration files share parameter defined for the IBM Spectrum Protect fixed content device. The following files are critical to the operation of the Content Platform Engine and must not be deleted. Include these files in all system backups and disaster recovery procedures.
Options files for UNIX servers
Each UNIX server where the Content Platform Engine is running must have the IBM Spectrum Protect client software installed. Within the IBM Spectrum Protect client installation folders there is a dsm.sys file, which is used by all IBM Spectrum Protect clients on that server, including the Content Platform Engine, to connect to the IBM Spectrum Protect. On UNIX servers, the DSMI Directory property of the IBM Spectrum Protect fixed content device must be set to the location of the IBM Spectrum Protect client software directory that contains the dms.sys file (for example, /opt/tivoli/tsm/client/ba/bin).
The Content Platform Engine maintains a shared version of the dsm.sys file in the folder that is defined by the Configuration files share parameter of the IBM Spectrum Protect fixed content device. The shared file is named IBMFileNetP8.dsm.sys. Each Content Platform Engine instance merges the changes it makes (and changes that other Content Platform Engine instances make) to the shared dsm.sys file into the local dsm.sys file on the server. This action keeps all local dsm.sys files in sync with the Content Platform Engine shared dsm.sys file.
You might want to mount the shared options file folder with the option uid=username, where username is the Content Platform Engine user account. Without this option, Content Platform Engine can create the shared options files successfully on the mounted folder; however, the files might not grant the user full control access, and Content Platform Engine cannot write the files.
Options files for Windows servers
On Windows servers, each IBM Spectrum Protect fixed content device has a separate options file that is in the folder referenced by the configuration files share property. The options file name consists of the object identifier of the IBM Spectrum Protect fixed content device (with the leading and trailing brackets removed) followed by the .opt file extension. On a Windows server, an additional file, IBMFileNetP8.opt, is generated. This file is typically empty.
