Celerra Network Server Command Reference Manual
The fs Commands
connections, set the -cgi option to n; FileMover then assumes the
web server has direct access to migrated file content on secondary
storage.
-connection <fs_name> -delete {-all| <cid>[,<cid>...]}
Removes an existing connection between the file system and the
secondary file system. All connections can be removed or just the
specified <cid>.
[-recall_policy {check|no|yes}]
Specifies the recall policy for any migrated file during the -delete.
check
(default) scans the file system for stub files that depend on
the connection and fails on the first one. no deletes the connection
without checking for stub files that depend on the connection,
and yes migrates the files back to the Celerra Network Server
before the connection is removed. If no is specified and stub files
exist, an I/O error appears when the file is read because the
connection no longer exists.
MODIFYING A
CONNECTION -connection <fs_name> -modify {-all|<cid>[,<cid>...]}
Changes parameters on an existing NFS, CIFS, or HTTP Celerra
FileMover connection.
[-state {enabled|disabled|recallonly}]
Sets the state Celerra FileMover operations on the specified file
system. enabled (default) allows both the creation of stub files
and data migration through reads and writes. If the state is
disabled
, neither stub files nor data migration are possible. Data
currently on the Celerra Network Server can be read and written
to in the disabled state.
If the state is recallonly, the policy engine is not allowed to create
stub files, but the user is still able to trigger data migration using
a read or write request from the secondary file system to the
Celerra Network Server.
[-read_policy_override {full|passthrough|partial|none}]
Specifies the migration method option used by the Celerra
Network Server, in the connection level or file system level, to
override the migration method specified in the stub file. none
(default) specifies no override, full recalls the whole file to the
Celerra Network Server on read request before the data is
returned, passthrough retrieves data without recalling the data to
the Celerra Network Server, and partial recalls only the blocks
required to satisfy the client read request.
