Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients


Space Management Objects

When you add space management to your file systems, the HSM client creates control files in a hidden directory named .SpaceMan. Table 22 provides a brief description of objects that are stored in the .SpaceMan directory in each file system to which you add space management. The HSM client requires these objects for processing.

Attention: The HSM client can create other objects in the .SpaceMan directory during space management processing. Do not delete or modify the .SpaceMan directory, its contents, or any of the file ownerships and permissions.
