What steps are needed for changing the host name for a Tivoli Storage Manager V6 server that is running on AIX?
The Tivoli Storage Manager V6 server requires that a few additional steps be taken when you change the host name for the machine that it is running on. These steps are needed to ensure that the database continues to function properly. If you do not complete the additional steps, you will receive errors when starting the server.
Complete the following steps to change the host name and reconfigure the Tivoli Storage Manager V6.1 servers on the system:
- Halt any Tivoli Storage Manager V6.1 servers that are running on the system.
- Change the host name on the system using normal operating system tools and procedures.
From the root user ID on the system, issue the command:
db2set -g DB2SYSTEM=<newhostname>
The db2set command can be found in the <instance directory>/sqllib/adm directory. The <newhostname> is the host name that the machine is being changed to.
To verify that the DB2SYSTEM value has been changed, issue the command:
This command displays all the configuration settings that are used by the database. Look for the DB2SYSTEM setting, which should now have the <newhostname> value.
- Edit the db2nodes.cfg file, which is located in the <instance directory>/sqllib directory. The file has an existing entry with the previous host name that looks like this:
0 oldhostname 0
Update the entry to use the new host name, like this:
0 newhostname 0
Save and close the changed file.
After completing these steps, the server should now start and run successfully.
