Cluster server connection

Good day,
I have recently installed a 2 node cluster server with SQL 2000 SP3 in my
network. and have found out that users connect to the Virtual cluster server
inorder to receive SQL services but they get the replay for the physical
node that holds the SQL.
I was wondering if this configuration can be changed so that the SQL servers
answers back with the IP address of the virtual server and not the physical
cluster.
the problem is that im working with a Firewall and we would like to restrict
the number of IP address that we expose to the world.
Thanks in advance
Oren Zippori
This is one of the wierd but unavoidable artifacts of clustering. You will
have to expose the host computer's IP addresses through the firewall.
Personally, I like to run my database servers on an restricted segment, just
to minimize the impact of stuff like this.

Cluster name with multiple IP addresses?

Can multiple IP addresses be assigned to a cluster and/or virtual name?
I have a 2-node Active/Passive cluster on a switched (not routed) network.
Each node has 3 NICs, each on its own subnet;
a) public/client access - 192.168.10.0
b) private/cluster traffic - 10.0.0.0
c) data backup network - 192.168.20.0
The cluster name "SQLCLST" and the virtual machine name "SQLSVR" have been
defined with IP addresses on the public/client network.
My backup software is cluster aware but because the traffic is separated via
switched network, I need the cluster and/or virtual machine name to respond
to IP addresses on two different subnets. Is this possible? Did this make
sense? ;)
TIA
It is not an uncommon request, nor is it too difficult. Once you have the
NICs and networks defined in the cluser configuration, you run the SQL setup
wizard to add the networks to SQL Server. To use them effectively, look
into connection-specific suffixes. That way you can force traffic to a
particular network.

|||Thanks for the quick info. Apparently it is a little more difficult than
that, heheh
I did not see any dialog/screen that allowed for the addition of new
network - only to modify node membership.
I have a ticket opened with MS. They have escalated it stating that they
don't even know if SQL will support this configuration and are attempting to
duplicate it in their labs. The MS SQL Data Engine Team manager stated they
may even have to look at the code...
Should you happen to have any detailed steps on making this work, I'd
appreciate it and apparently MS would too! LOL

|||OK, you are not trying to stack multiple IP addresses on a single NIC, you
are using a unique IP address for each NIC. That isn't a problem.
The problem comes from having the same DNS alias (network name) respond on
two different subnets. That is a networking issue, not a clustering issue.
I would use connection-specific domain suffixes to differentiate the
networks. Also, I would use DNS SRV records to abstract the names. I.E.
MySQLCluster points to the IP and port of the normal public NIC.
MySQLClusterBackup points to the IP and port on the backup LAN.
I have used this setup in the past and it works just fine.

Cluster Install Q

Hi All, Can I set up a cluster on my PC (through virtual server) Can
someone point me out the docs of how to do it?
Thanks much.
Yes. See
http://www.microsoft.com/technet/pro...y/cvs2005.mspx
for the details
You could also attend a 4 day class in which you cluster everything with
Virtual Server 2005 - see www.clusterhelp.com for details.
Cheers,

Cluster Install

We have a Win2003 EE A/P cluster running on a DELL/EMC CX300. There are 2
logical disks defined outside of the quorum. When I install the Virtual
server, I select the parent group of the disks which happens to be the SQL
Server resource group which contains all resources except the clsuter
specific items. When I finish, I can only see one logical disk from within
EM even though both are on the node I am working from . Any thoughts on how
to see multiple logical disks?Starting with a LUN that is a cluster resource. Add the disk resource to
the SQL Resource group if it is not there already. Make the SQL Service
dependent on the additionan disk resource (just like the existing disk.)
You will have to stop SQL to change the dependencies.

cloning servers with sql server on them

Anyone have any experience with cloning servers that have sql server
installed. I am wondering what will happen when the new virtual server comes
up using a different name. sql server takes it name from the server name.
Will it just automatically adjust or is there a process to deal with that?
Thanks.
If it's SQL Server 2005 and it has never run after installation, it will
"fix" itself upon first startup. Else, it's a simple process to
drop/register the new server name (just like in 2000). If you have other
objects in there name/server dependencies, well, that gets a little more
complicated.

|||Hello Jason,
If you rename a server with SQL 2000/2005 installed, you may want to use
sp_dropserver to drop old server name, and then run sp_addserver to add the
new server name.

Cloned SQL 2005 Install

I need a little help with a cloned SQL 2005 install. We have a couple of Virtual Machines that SQL 2005 was installed on. The install was orginally completed on <pc1> and then duped over to <pc2>. The problem now is that <pc2> is showing information from <pc1> everywhere. I have reviewd this document: http://msdn2.microsoft.com/en-us/library/ms143799.aspx, and it doesn't seem to help any. I have used the sp_dropserver command with 'droplogins' to try to recreate the logins for <pc2> but it's still showing the logins from <pc1>. Can someone please help me out, I'm not sure what I'm doing wrong here. Thanks!

Am I looking at a re-install here?

The doc says there is no need to re-install, but those commands just aren't taking care of the problem. When I run @.@.servername it does show the correct server as node 0, but the logins are still there from <pc1>. I deleted the 3 logins that were referenced to the old PC, now I just can't get them re-created for <pc2>

|||What logins are you referring to?
