Upgrading a PXE server on Linux or UNIX

This topic provides instructions for upgrading a PXE server on Linux or UNIX computer where the PXE server was not installed as part of the Application Server installation. (If the PXE server is installed as part of the Application Server installation, an upgrade of the Application Server also upgrades the PXE server.)

Before you begin

To perform the upgrade of the PXE server, you must have root privileges.

To upgrade a standalone PXE Server on Linux or UNIX

1. Log on as root.
2. Record the following settings for the PXE server:
   • Database connectivity information
     The PXE server uses the same database as the Application Server. One way to obtain this information is to start the Application Server Administration Console (also known as the blasadmin utility) and enter the following command:
     show database all
   • Host name and IP address of the PXE server
   • DHCP server location (local or remote)
   • TFTP root directory
     You do not have to record the name and location of the data store.
   • If you are using the Multi-Database mode, make a note of the additional database configuration parameters found in the <install directory>/NSH/br/deployments/_pxe/pxe-data-sources.xml file.
3. Make a backup copy of configuration files.
   If you are using the pxe.conf configuration override file, make a copy of the <install directory>/NSH/br/pxe.conf file.
   
4. Navigate to the directory that contains upgrade files and run the upgrade script for BMC Server Automation. (Script names follow the convention: BBSA<version>-<platform>.)
   The following message is displayed:
   A previous installation already exists.
Do you wish to continue (y/n) ?
5. Enter y.
   A message prompts you to choose a language for the installation program.
6. Enter the number corresponding to the language that you want to use.
   The following message is displayed:
   Welcome to the BMC BladeLogic Server Automation Release 8.3.00 installation script ...
A previous installation has been detected. This installation will be upgraded to BMC BladeLogic BMC BladeLogic Server Automation 8.3.00.
Do you wish to continue (y/n) ?
7. Enter y.
   Licensing text is displayed and concludes with the following message:
   Do you agree to the terms of the license agreement (y for Yes) ?
8. Enter y.
   A list displays the BMC Server Automation components to be upgraded and prompts you to continue.
9. Enter y.
   A series of messages is displayed, and then the upgrade script is complete.
10. Copy the backup of the pxe-data-sources.xml file into <install directory>/NSH/br/deployments/_pxe/pxe-data-sources.xml.
11. Merge the configurations of the <install directory>/NSH/br/pxe.conf and the backed up copy.

To upgrade a combined PXE and Appliction Server on Linux or UNIX

1. Log on as root.
2. Record the following settings for the PXE server:
   • Database connectivity information
     The PXE server uses the same database as the Application Server. One way to obtain this information is to start the Application Server Administration Console (also known as the blasadmin utility) and enter the following command:
     show database all
   • Host name and IP address of the PXE server
   • DHCP server location (local or remote)
   • TFTP root directory
     You do not have to record the name and location of the data store.
   • If you are using the Multi-Database mode, make a note of the additional database configuration parameters found in the <install directory>/NSH/br/deployments/_pxe/pxe-data-sources.xml file.
3. Make a backup copy of configuration files.
   If you are using the pxe.conf configuration override file, make a copy of the <install directory>/NSH/br/pxe.conf file.
   
4. Follow the Application Server upgrade steps.
5. Copy the backup of the pxe-data-sources.xml file into <install directory>/NSH/br/deployments/_pxe/pxe-data-sources.xml.
6. Merge the configurations of the <install directory>/NSH/br/pxe.conf and the backed up copy.
