Management of automatic activation of mailbox bases in DAG Exhange

Question

Good day!
There is a DAG with two Exchange 2013 nodes. On one server, all databases are active, on the other, all databases are passive.
I want to prohibit automatic database activation on a server with passive databases, i.e. I want to manage the activation of databases manually.

In the documentation, I found three pairs of activation control commands, but I did not quite understand what is the difference between them and which commands should I use in my case?

Suspend-MailboxDatabaseCopy –Identity DB-name \ server-name -ActivationOnly - disable activation
Resume-MailboxDatabaseCopy <DBCopy> - allow activation

Set-MailboxServer <ServerName> -DatabaseCopyAutoActivationPolicy Blocked - disable activation
Set-MailboxServer <ServerName> -DatabaseCopyAutoActivationPolicy Unrestricted - allow activation

Set-MailboxServer <ServerName> -DatabaseCopyActivationDisabledAndMoveNow $ True - disable activation
Set-MailboxServer <ServerName> -DatabaseCopyActivationDisabledAndMoveNow $ False - enable activation

Answer 1

use this command:
Set-MailboxServer <ServerName> -DatabaseCopyAutoActivationPolicy Blocked

Why? Because it does what you want. :)
https://learn.microsoft.com/en-us/powershell/module/exchange/set-mailboxserver?view=exchange-ps

this command stop replication to that database, so only use when performing maintenance on the server and you dont want any replication to occur to it.
So dont use this one:
Suspend-MailboxDatabaseCopy –Identity DB-name \ server-name -ActivationOnly

Only use this when you want to also move any active DBs on that server to another before blocking autoamtic activation

Set-MailboxServer <ServerName> -DatabaseCopyActivationDisabledAndMoveNow $ True

Answer 2

Hi @Pavel ,

Agree with Andy, In case your database are all activated on server 1, and you want to manually control the passive copies on server2, blocking the database copy auto activity could best meet your requirements.
