Question
What steps are needed for changing the host name for a Tivoli Storage Manager V6 server that is running on Linux?
Answer
Complete the following steps to change the host name and reconfigure the Tivoli Storage Manager V6.X servers on the Linux system (this document does not apply to V7.X):
1. Halt any Tivoli Storage Manager V6.X servers that are running on the system.
2. Change the host name on the system using normal operating system tools and procedures.
NOTE: It is important that the network and host configuration files are changed properly. If they are not, the Tivoli Storage Manager server may not start after completing the steps in this document with a "DB2_DATABASE_START_FAILED sqlcode -6048" error.
3. 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:
db2set -all
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.
4. 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.
The Tivoli Storage Manager server can now accept the new hostname.
WARNING: Changing the system hostname also has implications on the IBM Deployment Engine(DE), which may cause future Tivoli Storage Manager server upgrade failures. Please see the following TechNote regarding updating hostname for the DE to prevent upgrade failures:
