Prerequisites
BFS Issues
License to
Clients
The BFS issues each DMFS client the appropriate license level
after receiving information on the amount of disk storage it
manages on the client machine. If a license for the appropriate
level is not available, the BFS issues the client a license for the
next higher level. If all licenses are in use, the request is denied.
(For a description of DataMgr components, refer to
“Components” on page 1-4 in DataMgr Overview.)
For example, if a client has 3GB of space for management, it
needs a Level 1 license. If a Level 1 licenses is not available, the
BFS will try to issue a Level 2 license, and if there are none
available, it will try to issue a Level 3 license.
If a client attempts to use either file replication or multi-tier
migration, but the BFS does not have the appropriate feature
license, the operation will fail.
Registration
File Monitors
License
On the BFS, DataMgr maintains a registration file located in
/etc/bfs/registered. This file (an example is shown
below) monitors all levels of licenses that are authorized and in
use at any given time.
