My Client Access Array has no members....how to add, or remove and create new

I found that when people put the FQDN of the Client Access Array in their MAPI clients it immediately resolves to (changes to) one of the two Client Access Servers so I did some investigating.   Microsoft NLB is setup between the two CA Servers and there is an A-record in DNS for the  the virtual IP.  In Exchange Management Shell -  I ran the get-ClientAccessArray command and found that no members are present in the array...?.

[PS] C:\Windows\system32>Get-ClientAccessArray

Name                Site                 Fqdn                           Members
----                ----                 ----                           -------
CAS Array 1         Default-First-Site   client.domain.com                 {}

I'm looking everywhere trying find how to add the members and I'm not seeing an Add Member cmd but what I found is that when you create the CAS Array you don't specify the Members,  the New-ClientAccessArray Cmdlet finds the CA Server(s) associated in Active Directory to the Site that was specified...      So I guess I have two questions, can I added members to an existing Array manually?  How can I check the Site and if the CA Server are a member/associated to it.

Thanks!

can you run same command with | FL switch and post the result. Also note, if you created this Array after db creation, then you much set the rpcclientaccess value for old db's to CAS Array name.

The Array was created before the db creation, that is another thing I noticed, each db has the name of one of the CA Server.  I will change that after I get this Array situation figured out.

Appreciate the help!

Where are your CAS Member sever located. Which AD site. As Members are added automatically.

The subnet that they are in is linked to a site called Florida and that is not the Default-First-Site....     Ah!

I created a new one and that worked...    ]

[PS] C:\Windows\system32>New-ClientAccessArray -Name "CAS Array 2" -Site "Florida" -Fqdn outlook.domain.com

Name                Site                 Fqdn                           Members
----                ----                 ----                           -------
CAS Array 2         Florida              outlook.domain.com                {SEMCAS02, SEMCAS01}



The problem is now I need to delete this and the first one.  I need to use the FQDN from the first array with no members. (can't have two array's with the same FQDN or Site).

I'm going to try the Remove-ClientAccessArray Command

I found I was putting the Site name and not the FQDN in the identity parameter of the Remove statement, once I corrected that I deleted the Arrays.  I then created a new Array using the Florida Site where the CA Servers reside. The array created successfully.
