Move from active/passive cluster to active/active

Hi,
sorry for my lack of knowledge on this issue..
I've installed a Windows 2003 Cluster with SQL 2005. Works like a charm
when i do a failover.
Now i want to make this cluster active/active (multi instance) so no
connection is lost when a node goes down, but can't find any info on
how this need to be done. Can anyone help me out here..?!
Thanx in advance!
Hiddo,
"to make this cluster active/active (multi instance) so no connection is
lost when a node goes down"
When a cluster-group, or instance, moves from one node to another you do
loose your connection, as it offlines the group completely when moving.
Having a multi-instance, doesn't help, multi-instance is just another word
for having multiple virtual servers, they are still seperate in regards to
databases and connections. (e.g. if you have 2 instances, you can consider
them as being 2 different servers)
I do not think that your problem can be solved by server clustering.
HTH,

|||NLB is indeed different then failover clustering, however not really usable
with databases such as SQL.
You need to think of your requirements, and then match it to the right
technology option for SQL
Here are some links for reference:

Thanx for your support! It's become more clear to me now...
Nog 1 vraag ... : )
Hoe verwijder ik een Windows 2003 cluster in z'n geheel. Ik draai (voor
test) een 2-node W2k3/SQL2k5 cluster en deze wil ik dus in z'n geheel
verwijderen.
Wanneer ik op de eerst node 'take offline' kies en vervolgens Evict
Node gaat dit goed, alleen bij de 2de node krijg ik RPC errors
(waarschijnlijk omdat hierop het virtuele cluster ip nog draait..)
Gr,
Hiddo

|||Hiddo,
Good practice is to keep posts in these newsgroups in english. This so
others can read the posts and possibly help themselves solving problems.
There are however some newsgroups for some topics in your native language,
they have the microsoft.public.nl.... prefix.
In regards to your question of fully removing a W2K3/SQL2K5 cluster,
first, remove SQL instances:
http://msdn2.microsoft.com/en-us/library/ms190438.aspx
then, remove the cluster:

Good Luck !
Rgds,
