Moving logs of a CCR enabled storage group

Logs verplaatsen van een normale storage group is niet zo heel moeilijk, in het geval van een storage groep waarvoor CCR is ingeschakeld dien je een aantal dingen goed in de gaten te houden.

Het verplaatsen van de logs is vaak een eenmalige actie. De eerste storage group die aangemaakt wordt tijdens de installatie zet zowel de logs als de checkpoint file op dezelfde schijf als de database zelf. Dit laatste is niet echt aan te raden. Het is beter om de logs en de checkpoint file op een andere schijf te plaatsen. In het geval van een recovery zijn namelijk deze bestanden erg belangrijk.

When you would like to change the log path of a normal storage group it’s not very hard, but when you want to change the log path of a storage group which is CCR enabled then you will need to do a few more things.

In this tutorial I will explain how you can move the logs from the CCR enabled storage group.

For the first step we will need to open the Exchange Management Console, we will need to disable to log replication temporarily. This can be done by going to the mailbox server via server configuration. Then select the storage group and right click on it, the menu below will be displayed.

 Suspend Storage Group Copy

In this menu we select the option Suspend Storage Group Copy, a new screen will be displayed which will let you enter the reason why you suspend the copy, you don’t have to fill it in if you don’t like it.

Administrative suspend

The status of the CCR will be changed from healthy to suspended.

Now the CCR copy has been disabled temporarily we need to open the Exchange Management Shell to perform the reconfiguration of the log path. This can only be done via the Exchange Management Shell.

Move storage group logs via Powershell

By executing the command: move-StorageGroupPath -Identity ‘First Storage Group’ -LogFolderPath ‘E:\Mailbox\SG1’ – ConfigurationOnly we specify that we want to change the log path, files must be moved manually because the Powershell command won’t do it for you. Two confirmations will be asked, one for the reconfiguration of the log path and the other tells you that all databases within the storage group will be dismounted. Please be aware that the storage group will not be available to users at that moment.

When the command has been executed successfully you will need to move the log files and fileswith the jrs extension manually to their new location. When this is done you can enable the mount the storage group again via the Exchange Management Console by right clicking on it and choose the option mount.

Mount database

When the storage group and databases are mounted again you can enable CCR. This can be done by right clicking on the storage group and select the option Restore Storage Group Copy. After several seconds the status will change to healthy again. When you have a look at the properties of the storage group you will see that the log path has been changed to the new location.

Log path changed

In the previous versions of Exchange you need to do some tricks to create a resource mailbox. In Exchange 2007 it’s a default option to create one, via the both the GUI and the shell.

First we will add a box via the Exchange Management Console. This goes nearly the same as creating a user, select one other option and you have a resource mailbox.

In the first field we choose for a room or equipment mailbox in this example we choose for a room mailbox. And we will click next to continue.

In the next screen you have the ability to create a new user or assign the box to an existing user. We will create a new user.

The next step will be providing the user details, in this case we will create a user called boardroom. The password is pure formality and you don’t need it in most cases especially when you create a box which autoaccepts meetingrequests.

Click on next when ready

In the mailbox settings screen we decide on which mailbox server the mailbox will be created and in which storage group and mailbox database. The two policy options you mostly don’t user while creating a resource mailbox.

A few times clicking on next and the resource mailbox is created.

All the previous steps can be done faster with Powershell. Actually there are more option in Powershell then in the GUI. You can for example add the -room parameter to a resource mailbox of the type room to add accessoires. When choosing for a resource mailbox of the type equipment then you can use the –equipment  to do this.

New-Mailbox -UserPrincipalName boardroom2@test.local -database “First Storage Group\Mailbox Database” -Name “Boardroom 2” -OrganizationalUnit Users -DisplayName “Boardroom 2” -ResetPasswordOnNextLogon $false -Room

With the command above we will create a resource mailbox with the name boardroom2.

Let’s add some extra accessoires to it, for this we will need to do two things:

  • create the accessoire
  • add the accessoire to the resource mailbox

Creating new accessoires can only be done via Powershell:

Set-ResourceConfig -DomainController fqdn.dc  -ResourcePropertySchema Room/Networkprojector

In the exampe above we added a beamer to the list of accesoires. You can also add multiple accesoires at one time:

Set-ResourceConfig -DomainController fqdn.dc -ResourcePropertySchema (“Room/16Seats”,”Equipment/Projector”,”Room/8Seats”,”Equipment/Whiteboard”)

The next step will be to assign the accesoires to the resource mailbox. This can be done within the  Exchange Management Console. First we will need to get the properties of the resource mailbox and click on the tab Resource Information.

In the screen that opens you can click Add to add accessoires to the object:

A new windows will be opened where we can select the beamer we just created and assign it to the resource mailbox.

It would be easier if the boardroomcan autoaccept meetingrequests and look for availability of the room. In Exchange 2003 this was already possible via a few clicks, in Exchange 2007 this can easily done via the Powershell:

Set-MailboxCalenderSettings boardroom -AutomateProcessing:AutoAccept

In case you would not like to use the autoaccept functionality you need to assign delegates to the resource mailbox

Set-MailboxCalenderSettings -Indentity “boardroom” -ResourceDelegates “Pietje Puk”

In the example above we will assign Pietje Puk as a delegate of the boardroom.
