Since HSMS does not support the migration of node files via POSIX, there is only one storage level. Within this manual, this level is referred to as “node S0”.
The node S0 storage level comprises a number of node S0s. Each node S0 is named for the remote computer on which a file system is normally processed. Only the node S0 which corresponds to the local BS2000-UFS has no name.
Each node S0 contains one or more file systems, depending on the mount processes activated by the BS2000 system administrator.
Access to the node S0 and its files, referred to as node files, is made possible by a definition in the tree structure of the local BS2000-UFS:
Note
Within the context of HSMS, a “remote file system” is a file system with the following attributes:
It has been mounted under the “HSMS” directory.
It is subordinate to a specific node S0.
It can be reached from the BS2000 root directory.
It permits access by BS2000.
It is mounted in the local BS2000-UFS.
