Before installing the Tivoli® Storage
Manager for Space Management client on any system,
review the general requirements and considerations.
Installation prerequisites
You must install
the Tivoli Storage
Manager backup-archive
client and you must have authority to install the Tivoli Storage
Manager for Space Management client.
- You must have root user authority to install, set up, and use
the Tivoli Storage
Manager for Space Management client on
your workstation.
- You must install and set up the Tivoli Storage
Manager backup-archive
client before you install the Tivoli Storage
Manager for Space Management client. Both the Tivoli Storage
Manager for Space Management client and Tivoli Storage
Manager backup-archive
clients share common code, the same options files, communication protocols,
node registration, and storage.
Pre-existing files in the installation directory can
be deleted
The
/usr/tivoli/tsm/client/hsm/bin
directory is one of the base directories into which the
Tivoli Storage
Manager for Space Management client product is installed.
Any files that you place in this directory might be deleted during
installation. Do not place the following files into this directory:
- dsm.opt files
- dsm.sys files
- Include-exclude files
- User-created files
Installation steps overview
The following
steps are an overview of the installation procedure.
- Before installing anything, read all of these general requirements.
Read your system installation overview, specific environment requirements,
and each installation step to ensure that you are ready to install
the Tivoli Storage
Manager for Space Management client.
- Follow your system-specific installation procedure.
- When you complete the installation, register your workstation
as a node with a Tivoli Storage
Manager server.
- Modify the dsm.sys and dsm.opt configuration
files. Both files are in the following directory:
- For AIX®: /usr/tivoli/tsm/client/ba/bin
- For Linux: /opt/tivoli/tsm/client/ba/bin
Reinstallation or upgrade overview
Before
you reinstall the Tivoli Storage
Manager for Space Management client,
stop all activity and do not access any files on file systems to which
you added space management. The installation process fails otherwise.
Follow the upgrade procedure as described for your operating system.
If the steps tell you to uninstall and reinstall the backup archive
client and API, you must complete those steps. Uninstalling and reinstalling
brings those packages to the same level as the Tivoli Storage
Manager for Space Management client.
You must
not upgrade with a command like rpm -U. You must
not refresh with a command like rpm -F. You must
uninstall the old version and then install the new version.
Tivoli Storage
Manager for Space Management client limitations
and considerations
The Tivoli Storage
Manager for Space Management client has limitations.
- The Tivoli Storage
Manager for Space Management client for AIX GPFS™ systems
is not compatible with the backup-archive client for JFS2. Journal-based
backup is not supported when the Tivoli Storage
Manager for Space Management client for AIX GPFS systems
is installed.
- The Tivoli Storage
Manager for Space Management client for GPFS systems manages only file systems belonging
to the local (home) GPFS cluster;
it does not manage remotely mounted file systems.
- In a GPFS environment, a small file that
is less than the size of a GPFS block size can become larger
after an HSM migration. GPFS adds meta information to the file
during the migration. Because another block on the file system is allocated for the meta
information, the space allocated for the file increases. If a file system is filled to its maximum
capacity with many small files, it can run out of space during the file migration.
- On a GPFS cluster with Linux and AIX nodes,
install the Tivoli Storage
Manager for Space Management client on Linux nodes only or on AIX nodes only. Do not
install the Tivoli Storage
Manager for Space Management client on Linux nodes and AIX nodes that are on the
same GPFS cluster.
- On a GPFS
cluster with Windows systems and UNIX systems nodes, you must run backup-archive client processes on the same node
that runs HSM processes.
- The Tivoli Storage
Manager for Space Management client is not supported
on JFS2 Encrypted File Systems (EFS).
- Extended attributes (EAv2) are supported by
the Tivoli Storage
Manager for Space Management client.
However, if you delete a stub file and use the dsmmigundelete command
to re-create the stub file, the extended attributes are not restored.
