The HSM client provides several commands that you can use to perform utilities tasks. This chapter describes these utilities.
You can display space management-related information about each of your file systems in a list format or a pie chart format from the graphical user interface (dsmhsm). Click Space Manager in the Hierarchical Storage Management window. The Space Manager window displays.
In the Space Manager window, you can:
The migration and recall processes dynamically update status information. If another process changes a file, the change is not reflected in the Space Manager or View as Pie Chart windows until reconciliation runs. For example, if you restore a backup version of a migrated file, the information in the View as Pie Chart window for local disk space, server disk space, and local disk inodes does not reflect the change until reconciliation runs. Or, if you use any command that changes the ctime of a premigrated file (causing the file to become resident), that change is not reflected in status information until reconciliation runs.
You can use the commands that are listed in the following table to display
space management information about your file systems, files, and
directories. For information about each of these commands, see Hierarchical Storage Management Commands.
Table 16. Displaying Space Management Information
Command | Description |
---|---|
dsmdf | Displays space usage information for a file system. For example,
to display space usage information for the /home file system,
enter:
dsmdf /home See dsmdf for more information about this command. |
dsmls | Lists files in a directory and displays file conditions. For
example, to display information about all files in the /home/user1
directory, enter:
dsmls /home/user1/* See dsmls for more information about this command. |
dsmdu | Displays space usage information for files and directories. For
example, to display space usage information for each file in the
/home/user/proj1 directory and in all of its subdirectories,
enter:
dsmdu -Allfiles /home/user1/proj1 See dsmdu for more information about this command. |
dsmmigfs | Displays the current space management settings for a file system.
For example, to display the space management settings for the /home
file system, enter:
dsmmigfs query /home
See dsmmigfs for more information about this command. |
dsmmigundelete | Recreates deleted stub files for migrated files and creates stub files
for premigrated files if a corresponding original file does not exist on your
local file system. The file then becomes a migrated file. For
example, recreate stub files for migrated files in the /home file
system that are not marked for expiration. Reconciliation was not run
since the files were deleted:
dsmmigundelete /home |
