If you need to team NICs on an HP, make sure you install the ProLiant support pack first. You can find instructions for this in the knowledgebase. The support pack includes a command-line utility called cqniccmd.exe, which lets you do a lot of things with the NICs. You can do this to record your current NIC configuration:
cqniccmd /s nicteam.xml
So configure the server locally, then record. You can also dissolve teams with the /d option. Then, you can create a BLPackage with the nicteam.xml and then add an external command like this:
set path=%path%;C:\Program Files\HP\NCU
start cqniccmd /c C:\Temp\nicteam.xml
You need to execute this with the start command because you will lose connectivity. If you are executing this as part of a batch, be sure to throw in an NSH wait script or any other creative way of waiting for an agent to come back online.
i think you can set the package to 'out of band' reboot
