I was recently asked if there was a way to have 2 scalability servers acting as boot servers on the same subnet but for different ITCM environments. In the example given there were 2 companies that share the same branch office. They both want to use OSIM but cannot have the other boot server responding to their PC's PXE requests.
The good news is that this is very easy to configure.
There is a configuration parameter for OSIM specifically designed for this type of situation
The default configuration is 1 which is not suitable for the scenario above as both boot servers can answer all PXE requests on the subnet.
For this scenario the correct setting is UseACL=2
Each Boot server will now only respond to PXE requests from computers that are already known to the boot server.
This does however mean that the OSIM targets will not automatically be populated as OSIM targets when they PXE boot instead it is required to manually register the target PC with the boot server.
This is achieved in 1 of 2 ways
Using either of these methods will register the PC to the boot server and allow it to be targeted for an OSIM job
Good Tip Rich
Nice one Rich.
