Exchange 2010 - DAG maintenance issue

[PS] C:\Windows\system32>cd $exscripts

[PS] C:\Program Files\Microsoft\Exchange Server\V14\scripts>.\StartDagServerMaintenance.ps1 -serverName Server1.example.local

Make sure that DatabaseCopyAutoActivationPolicy is in Blocked state
[PS] C:\Program Files\Microsoft\Exchange Server\V14\scripts>Get-MailboxServer Server1.example.local | fl

If not use:
[PS] C:\Program Files\Microsoft\Exchange Server\V14\scripts>Set-MailboxServer Server1.example.local -DatabaseCopyAutoActivationPolicy Blocked

When you try to run StopDagServerMaintenance.ps1 you get error:

[PS] C:\Program Files\Microsoft\Exchange Server\V14\scripts>.\StopDagServerMaintenance.ps1 -serverName Server1.example.local

It is because you enter full FQDN of server instead of NetBios name. Also don not forget to run Exchange Management Shell as administrator. To run script properly use:
.\StopDagServerMaintenance.ps1 -serverName Server1

  1. Try placing the server into maintenace mode from one of the other nodes and you'll find that works fine.

  2. This can be caused in a two node DAG, if StartDagServerMaintenance.ps1 encounters any errors (red warnings on the ps input) it will back out all the changes except moving mailboxes from active to passive dag server. It will not pause the cluster or block activation.

    The reason you are getting this is the stopdagservermaintence script is trying to activate stuff that the startdagservermaintenance didnt actually complete.
    As long as you can switchover all databases manually and that activation isnt blocked you should be good. script below to check activation.
    Get-MailboxSERVER | select NAME,*ACTIVATION* | ft –auto
