IBM Tivoli Storage Manager for Space Management for UNIX: User's Guide


Using Utilities

The HSM client provides several commands that you can use to perform utilities tasks. This chapter describes these utilities.


Displaying Information About Your File Systems

Note:
A graphical user interface is not available on AIX GPFS.

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.

Note:
Some column headings in the File System view might appear shortened. To display the complete headings, specify a larger column width on the Tivoli Storage Manager Column Layout for Space Manager window. To open the Column Layout window, select Column Layout from the View menu.

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.

Display Information from the Command Line

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
