Several NSH scripts are offered by BMC Software for setting up and managing an additional BOS instance on an AIX server with multibos, to enable patch management using BMC Server Automation.
You can find more information about these scripts in the relevant topic in the BMC Server Automation online documentation.
For most versions of BMC Server Automation, these scripts are available from the EPD site, in the AIX_Multibos_Scripts.zip package within the BBSA##-Optional.zip package (where ## is the BSA version number).
The AIX_Multibos_Scripts.zip package is missing in the EPD page for version 8.7 of BMC Server Automation. For this version of BSA, you can download the package attached to this page.
