About Partial Releasing and Partial Staging
This chapter describes the releasing process and releaser operations.
Releasing is the process by which the releaser makes disk cache space available by identifying archived files and releasing their disk cache copy. This action makes room for other files to be created or staged from archive media. The releaser can release only archived files. A released file has no data on the disk cache.
The Sun Storage Archive Manager (SAM) software invokes the releaser process when a site-specified disk threshold is reached. As an alternative, you can use the release command to release a file's disk space immediately or to set releasing parameters for a file.
You can also specify that files are released immediately after archiving, that files are never released, or that files are partially released.
