| Sun StorEdge QFS Installation and Upgrade Guide
|
   
|
The Sun StorEdge QFS environment consists of a file system, daemons, processes, various types of commands (user, administrator, and so on), and tools. This appendix describes the commands that are included in the Sun StorEdge QFS software distributions.
The Sun StorEdge QFS commands operate in conjunction with the standard UNIX file system commands. All the commands are documented in UNIX man(1) pages.
This appendix contains the following sections:
User Commands
By default, file system operations are transparent to the end user. Depending on your site practices, however, you might want to make some commands available to users at your site to fine-tune certain operations. TABLE C-1 summarizes these commands.
TABLE C-1 User Commands
|
Command
|
Description
|
|
sdu(1)
|
Summarizes disk usage. The sdu(1) command is based on the GNU version of the du(1) command.
|
|
setfa(1)
|
Sets file attributes.
|
|
sfind(1)
|
Searches for files in a directory hierarchy. The sfind(1) command is based on the GNU version of the find(1) command and contains options for searching based on Sun StorEdge QFS and SAM-QFS file attributes.
|
|
sls(1)
|
Lists contents of directories. The sls(1) command is based on the GNU version of the ls(1) command and contains options for displaying file system attributes and information.
|
|
squota(1)
|
Reports quota information.
|
General System Administrator Commands
TABLE C-2 summarizes the commands that you can use to maintain and manage the system.
TABLE C-2 General System Administrator Commands
|
Command
|
Description
|
|
fsmadm(1M)
|
Starts or stops the fsmgmtd daemon.
|
|
fsmgr_setup(1M)

Application Programming Interface
You can use the application programming interface (API) to make file system requests from within a user application. The requests can be made locally or remotely to the machine on which the file system is running. The API consists of the libsam and libsamrpc libraries. These libraries contain library routines for obtaining file status; for setting archive, release, and stage attributes for a file; and for manipulating the library catalog of an automated library. The sam-rpcd remote procedure call daemon handles remote requests. To automatically start the sam-rpcd daemon, set samrpc=on in the defaults.conf file.
For more information about the API, see the intro_libsam(3) man page. This man page provides overview information for using the library routines in libsam and libsamrpc.
Operational Utilities
Within the Sun StorEdge QFS environment, you can use the samu(1M) operator utility and File System Manager to perform basic operations. TABLE C-4 summarizes the operational tools.
TABLE C-4 Operational Utilities
|
GUI Tools
|
Description
|
|
File System Manager
|
Provides a web-based graphical user interface to the Sun StorEdge QFS software. You can use this interface to configure, control, monitor, and reconfigure the components of your Sun StorEdge QFS environment. For information on installing File System Manager, see Installing and Using the File System Manager Software. For information on using the File System Manager, see its online help.
