Creating a database availability grew the initial set up and configuration of a database availability.
Group is done using a single command land which is named new database availability.
Group first introduced in exchange to Southern seek 13 Service Pack 1 the IPL s dog also known as Doc
without an administrative access point is now available and the norm in exchange 2016 which is good
as it greatly simplifies the creation of dogs.
It generally means that IP addresses are no longer required for the cluster or name object the network
name resource or for the dog.
The only downside to this sort positive under support before implementing an appeal as dog is strongly
recommended that you ensure that any third party software that integrates with exchange such as backup
solutions supports IPL as dogs.
Please know that while Windows Server 2012 supports exchange 2016 dogs only Soros 2012 are two and above
support.
I appeal as dogs and this video will take a look at how you can automate the creation of a dog using
the exchange management.
Shall I also show how to create dark use in graphical user interface.
In case you need to perform this task in such a way now to create a dark youth new database availability
Group Command led you could type the following one liner new database availability to group dash name
dog.
Witness or in my case its long odyssey one but in your case it could be an it somewhere in your network
except a member of the dog.
Next we will create.
We will set up witness directory which will be located on Long display one on C drive and will be named
first W and we also our set and database the reliability group IP addresses parameter.
So in this command we are creating a new database a real ability to group named Dog they file share
witness terrorists said to the Exchange server or any other server.
In my case its domain controller which is named lambda C1 and the pass for the director is also specified.
Remember that the witness server cannot be a member of the dog in order to create an IPL as Doc will
use system dot now dot IP address class set to long to specify that this doc will not have an administrative
access point.
This is because a change will attempt to obtain an IP address for the doc you then disappear if you
do not provide an IP address for the doc.
That is if you do not to use their database availability group IP address parameter.
Therefore we have to use the precedent notation to specify that we do not want an IP address for our
doc.
Now when you run the new database availability group come and let the only requirement is that you use
a unique name for the doc of up to 15 characters in the previous example.
We also specify the information for the file share weirdness but these values are optional for your
information.
The witness summaries is a quorum resource used by Windows failover clustering as a tie breaker in docks
with an even number of nodes.
So if you do not provide her well for the witness server or a witness server director exchange will
attempt to locate an exchange server in the current active directory site.
One will be selected automatically and the configuration of the witness server and its director will
be taken care of by exchange.
If you create a doc you have the minimum amount of information you can all this come back later and
modify the configuration.
For instance say we first issue the following command out new database availability.
Group name Doc and at this point the doc will attempt to automatically configure the witness server
details and will try to obtain an IP address using DCP.
You can retrieve the sentence for the doc you then get database availability.
Group Command lad.
So let's run it now.
Get database availability.
Group Doc and will get the information on this particular availability.
GROUP We can update the doc using the set database availability.
Group Command glad to modify the settings.
For example we can type the following command set database availability.
Group dark witness server.
Some new witness server witness directory some new witness directory and database availability.
Group IP addresses.
And here we have to specify the IP addresses of our servers.
You do not have to place the witness directory on another exchange server for example it's quite common
for small and medium sized organizations to utilize to exchange servers other to node dark alone with
a hardware load balancer to provide high reliability for client connections.
In this case you could use a member server in the domain as the witness server.
Just make sure that the exchange trusted subsystem security group in active directory is a member of
local administrator group on the server.
You can now also use a Microsoft Asia file server virtual machine to act.
The docs witness server when you are planning to add servers that are located in safe separate IP subnets
and assume in your reuse and a dock with an IP address.
You'll need to specify an IP address that can be used by the dock in each of the corresponding networks.
For example you could run the following command new database availability group name dock and database
availability to group IP addresses.
Turn that one that one the turn for example and 119 to dot 168 dot 1 dot.
And this example one of the dock members will be in the down turn.
That one dot one dot zero slash 24 subnet and the other in the 192 dot 168 dot 1.0 slash 24 subnet This
will allow the cluster IP address to be brought on line by a server in either side.
If you have already created the dark and need to change the addresses use the set database availability.
Group Command with database availability IP addresses parameter and the command itself will look like
these said database availability.
Group identity dark database availability.
Group IP addresses and the addresses you name.
Once again this is not required when using a dock without an administrative access point making it much
simpler to create and manage docks with members on different subnets.
Now when we are done with create and docks with power shell let's do it with the help of Google.
So in my case I log in to long DC 1 and in server manager click tools and then click active directory
user or send computers inactive directory users and computers on the menu bar I'll click view and then
click Advanced features in the left pane I'll expand a datum dot com click computer sound right click
computers and orient to new and then click.
Computer is the new object.
Computer dialog box in computer name field tile type dog one and then click Okay.
Then click computer send them in the right pane click right click dock one and then click properties
in the dark one properties dialog box I'll click the security tab and on the security tap I'll click
add and then and then enter the object names to select field I'll type exchange trusted subsystem and
click change names and then click Okay.
Then on the security tab I'll click add and then click object types and the object types dialog box
I'll click computers and then click Okay further in the select users computer service accounts or group
window and to enter the object names to select books.
I'll type along dash E X one dollar character and click check names and then click Okay.
Further on the security tab I'll select Lon exchange and then in the allow column in the permissions
for along exchange one list I'll click full control.
Also on the security tap I'll select exchange trusted system subsystem and in the allow colon in the
permissions for exchange trusted subsystem list.
I'll click full control and then click Okay.
Then in the active directory user research computer's window in the right pane.
I'll right click deck dug one and then click disable the card in the warning window.
I'll click yes and then the next information window click okay and I'll close the Active Directory user
ascend computers and switch over to the long exchange one server
on long exchange one in the exchange administrative center in the feature pain aisle click servers on
taps.
I'll click database availability to groups and them on the toolbar I'll click on you.
That is the plus sign and in the new database the reliability group window in the database availability
Group Name field.
I'll type dog one and then in the witness server field I'll type along the C1 and in the Witness director
Phil tell type C colon backslash fast w dark one director a name.
Then I'll click enter an IP address and in database availability.
Group IP addresses field.
I'll type 172 dot sixteen dot zero dot thirty three please remember that you can skip this step and
you don't have to type the IP address here.
Then you have to click ad and then click save.
Only step you've successfully created dog but if you want to add mailbox servers to this dog then in
the list you you have to click dog 1 and then on the toolbar click manage dog membership and in the
manage database availability group membership window.
You have to click and aren't in the select server window click your database Soros sorry mailbox Soros.
In my case I have to click on long exchange one click ad and then click on exchange 2 and click ad again
and click.
Okay.
This will take some time.
The server as I read it.
This dog after it is done you have to close this window and of course you can modify the sentence in
this window by adding yo servers or IP addresses and so on.
Or you can just delete the existent doc from this window as well.
So for now I don't need this example demonstration Doc 1.
I'll just remove it with his bottom.
