Optional setup features

You can specify which files are eligible for migration. You can use clustered file systems and LAN-free data transfer and set logging options.

Assignment of management classes to files
A management class indicates a storage policy for a file. The storage policy determines whether a file can be migrated and how the migrated copy is stored.
Displaying management class information
To display information about management classes, use the dsmmigquery command with the -mgmtclass parameter.
Include-exclude file options
You can use an include-exclude options file to exclude or include specific files from space management and to assign specific management classes to these files. For example, you might want to keep certain files, on your local file system always, and thus need to exclude them from migration. Or, you might also want to include certain files for backup or migration.
Environment variables
Environment variables determine where IBM Spectrum Protect clients create program files.
LAN-free data transfer for HSM
The space management client supports LAN-free data transfer, which shifts the movement of client data from the communications network to a storage area network (SAN). Shifting the client data movement from the communications network to a SAN decreases the load on the IBM Spectrum Protect server.
Configuring HSM on IBM Spectrum Scale clusters
IBM Spectrum Scale is a high-performance cluster file system, providing concurrent access to one or more file systems from multiple nodes. You can configure a space-managed file system to become a part of a resource group in an IBM Spectrum Scale cluster. If there is a system failure, you can access your data from another system.
Logs for HSM activity and error messages
The space management client logs HSM activity and error messages. An HSM log contains information about file migration and recall, threshold migration, reconciliation, and starting and stopping the HSM daemon. An error log records error messages.
