HI, I have a specific requirement in SCOM 2007 R2, I need to add computers to a group using Powershell. The reason is we have around 500 windows servers to be patched on a monthly basis for Microsoft patches which are released every month, this task is done batch wise, e.g. 50 servers on day 1, the another 50 on day 2 and so on. And during this patching activity we have to put the server in SCOM maintenance mode(MM) before restarting the server or else we get a SCOM alert when the server is restarted without MM. At present this task is very hectic to add each and every computer in MM from the SCOM console, also I have tried to add the computers in a group and scheduling the group in MM (using the SCOM Remote Maintenance mode Scheduler 2.0), this is not feasible as the patching or restarting time for any server is not fixed and it depends on the production and Application team approval, so I have to change the group members every time. I was thinking of a Power shell script or any other method where in I can provide a name of servers in a source file(.txt or .csv) and run the command which would add all the servers from the source file to the group and then I can schedule the group in MM. Just thinking if it’s feasible and if anyone has tried this ?
