Hello,

I am trying to setup a 2-node cluster on W2k3 and SQL 2005 in our lab.

In cluster Admin console, I have the following groups/resources:

For Node A:
Cluster Name: NodeA

Groups:
1. Cluster Group
IP Address: .....188.111
Network Name: HubNodeA
Physical Disk: Disk Q: This is the quorum drive. Q: drive.

2. MSDTC
IP Address: .....188.112
Network Name: HUBMSDTC
Physical Disk: Disk T: Just a logical drive on the SAN for SQL
data.
DTC: Distributed Transaction Coordinator

3. SQLA Group for Node-A
IP Address: .....188.118
Network Name: RAS040SQLA
3 Physical Disks: F: G: H: SAN drives for SQL Data, backups,
logs

When attempting to install a SQL instance to Node-A....
Named Instance: INST1
Virtual Server Name: RAS040SQLA. A DNS alias exists. I get the
following error: Virtual Server Name already exists on the network. Why
does this error get generated? How does the VSN relate to the Network name
in Cluster Admin?
Because of the error, I use RAS040RLSQLA as the VSN. This is accepted by
SQL setup program.
IP address: ......188.118: I get the error, "IP Address already in use.".
What causes this error? Is it because of the IP Address for group SQLA?
If I delete the IP Address resource from the Group SQLA, then this IP
Address will work.

So, I need to understand the relationship between the IP Address and Network
Name resources in Cluster Admin and the Virtual Server Name and IP Address
used to install a SQL instance.

Setting up groups and resources in Cluster Admin.

I need to setup Groups & resources in Cluster Admin. for the following:
1. For the SQL Instance
2. To cluster MSDTC
3. To cluster SQL SSAS
4. BizTalk Enterprise Single Sign-On

How should I configure these in the Cluster Admin, and when should I create
them?
In other words, what do I configure in Cluster Admin prior to running SQL
setup and what should be created after running SQL Setup? In SQL, I need the
following:
1. SQL Server Database Services
2. SQL failover cluster
3. Analysis Services
4. Analysis Server for failover cluster
5. Notification Services
6. Workstation components, BOL, Dev tools

Sorry to be long-winded but wanted to provide all the details.

TIA,
DetRich

Hi DetRich,

I beleive you may have created a Host (A) records for the virtual name.
Since there are DNS entries exists for the Ip and the name, it would have
popped up with "The name already exists" / "Ip address already in use"
warning messages..(maintening uniqueness in the domain)

And have a look at the link below, which may help...
