TSM-Server, Port-Nummer und Nodename des Backupknotens ermitteln
Note:
For optimization reasons (load distribution, performance, ...) several server instances (logical TSM servers) are operating on the backup system of the IT Center.
In order to be able to distribute resources optimally, carry out backup and restore processes as quickly as possible, nodes of a facility are not assigned to a fixed TSM server, but are usually set up on different TSM servers.
To find out the corresponding information of your backup node, log into the Backup/Restore & Archive Self-Service Portal and click Backup in the left column under the Node tab.
To view the information, click the information("i") icon of the corresponding backup node in the table that appears.

Hinweis:
After installing the client software, the central configuration files (dsm.sys, dsm.opt) must be created.
To do this, execute the following commands.
touch /opt/tivoli/tsm/client/ba/bin/dsm.sys touch /opt/tivoli/tsm/client/ba/bin/dsm.opt |
Then use an editor of your choice to edit the dsm.sys.
The command to edit the file with an editor could be for example nano /opt/tivoli/tsm/client/ba/bin/dsm.sys.
Please copy the lower content of the dsm.sys and adjust the user-specific entries of the following parameters.
For this, use the data determined from the Backup/Restore & Archive Self-Service Portal(Link).
- DEFAULTSERVER
- SERVERNAME
- TCPSERVERADDRESS
- TCPPORT
- NODENAME
Hinweis:
DEFAULTSERVER, SERVERNAME and TCPSERVERADDRESS all have the same entry in the form of basXX.itc.rwth-aachen.de.
Replace the XX with the number of the according backup server.
With DOMAIN and VIRTUALMOUNTPOINT you define the directories to be backed up.
You can find more information about this in the content of dsm.sys.

Hinweis:
The parameter PASSWORDACCESS out of the configuration file (dsm.opt) generates a new, secure password for the client and server after the first entry of the node password.
This password is stored encrypted locally in the context of the current user and the entered password is discarded.
After the first connect with the backup node, it is no longer necessary to enter the password again.
For more information on the INCLUDE and EXCLUDE parameters, see the IBM documentation.
Abschließende Konfigurationen
Run the following command to add IBM Spectrum Protect to the init-system (systemd).
cp /opt/tivoli/tsm/client/ba/bin/dsmcad.service /usr/lib/systemd/system/ |
Type the following command to create an override file that will be additionally loaded by systemd when the service starts.
More information about this mechanism can be found here.
systemctl edit dsmcad |
Copy this content into the new window and save the file.
[Service] Environment="LANG=en_US" Environment="LC_CTYPE=en_US" |
Hinweis:
These overwrites ensure that characters of all character encodings are properly backed up. Please use "en_US" only, even if you otherwise use a different character set in your system.
To ensure that the character encoding works properly when using the Interactive Console, please perform the following steps each time before starting the CLI or GUI:
export LANG=en_US export LC_CTYPE=en_US |
Then you can reload the systemd manager configuration to make the changes effective.
systemctl daemon-reload |
Initial connect with the backup node
After all configurations have been made, you can establish the first connection to the backup node.
Run the dsmc in the console and enter the node name and the initial password.
After the successful Connect you can close the dsmc again with quit.
Hinweis:
If the connection was successful and you have set the parameter PASSWORDACCESS to generate in dsm.sys, it should now be possible to execute the dsmc again without password confirmation.
Activate the automatic start of the Client Acceptor Daemon
Finally, the automatic start of the Client Acceptor Daemon (CAD) is activated and the configuration of the client software is completed.
systemctl enable dsmcad systemctl start dsmcad |
You should now see entries in the log files.
