I am trying to get a task done in which I require to run a silent installation of the SQL server Service Pack on multiple servers. The catch here is that this is to be done in non working hours for my organization and hence I am trying to get a method using which i can schedule this silent installation to run on multiple servers at a time/one by one and then when the silent installation is complete or fails, I can check it out the next day.
Now the command for the unattended installation is :
<service pack path> /quiet /allinstances
which is a command shell, so I am looking forward for a way using which I can setup this command to execute on the server at a nonworking time, but I have failed to find a solution.
