Hello,
We have an EPO test coming up in one of our data centers that requires me to power off 2 of our 4 DAG members. In preparation for this I’ve been reading up on DAG member maintenance best practice as well as deconstructing the Start[Stop]DagServerMaintenance.ps1 script. After testing in my lab I noticed that the iteration of Suspend-MailboxDatabaseCopy is followed by the parameter -ActivationOnly and sets ActivationSuspended to True. Why only suspend copy activation and not database copy processes? Does the script assume that DAG member maintenance does not include server shutdown or is suspending database copy processes not actually necessary?
Also, one of the DAG members I have to power off serves 1 of 3 of our PF databases. I’ve noticed that the Start[Stop]DagServerMaintenance.ps1 scripts do nothing for PF databases. Should I just unmount it and rely on standard PF replication to update it when I mount it back? Do I need to change my databases over to use a different PF database?
The power-off duration is 6 hours so I'm not too worried about log build up. Our CAS servers are VMs and will be “motioned” to our other data center. We have two Hub Transport servers, I plan to simply power one of them off. Am I missing anything?
Thanks!
