Hi Our Company is having an emergency network outage next weekend for 6hrs, possibly longer.
I have a SCOM 2012 SP1 management group with 6 management servers in our office which will be effected, and 13 gateway servers around the world which connect to 3 of the management servers with the agent count fairly evenly distributed amongst the three management servers. The site with the largest agent count has around 750 agents, with two gateways and the agents split between them. The other gateways have between 200 to 400 agents connecting to them. During the network outage the gateways will not be able to connect to the management servers, and the management servers will lose connection to the Operationsmanager and WareHouse DB servers. I have three plans in mind, but not sure which is the better of the two, or if there's a cleaner way of managing the outage. Any advice would be appreciated Plan 1 Put all agents into maintenance mode at the windows computer level before the network outage, so only discoveries are processed. When the network outage accrues, the gateways and the agents will queue the discovery data until network connectivity returns. Plan 2 Put all agents into maintenance mode, then shut down the management servers and DB servers until the network is back. Plan 3 Leave as is, let gateway and agents queue data till network connectivity returns. Also what is the process for a Gateway/Agent's queue when it can't connect to its Management Server/Gateway, does the queue fill up to a certain size, or till the disk is full? Kind regards Gareth Miles
