Hello again,
If i understand you correctly, yes you can either push updates from SIM for one or more servers. Or you can log into every individual server and update manualy. As you can see not all package can be updated through VCA. HP is moving away from VCA and uses SIM in a combination with Hp SUM for software/ Firmware updates. HP SUM can also be used directly from the SPP folder to update local, remote or even complete Enclosures. The SIM angle can also be used to update using HP SUM and in addition to this can check your baselines.
Kind regards,
Andrew
