Question regarding configuration of an Active/Active cluster

Hey. I've a Active\Active with SQL 2000 on the nodes right now. I've to migrate to SQL 2005 and needed some help regarding using accounts.

Should I use the same account for the cluster service and the SQL Server/Agent service? If not what are the permissions I've to give to the cluster service account in SQL? I've a cluster with 2 nodes. What permissions should the SQL account be given on the box? Should it be a local admin or when installing, I give it the account and let SQL worry about giving permissions to the box? Thank you.

Tej,

According to MS:

- You should have different accounts for the cluster and SQl. Reason for this is that if the cluster account password changes, it does not affect SQL.

- You should create these account as normal domain user accoounts , but give them admin privileges on the SQL servers. When installing/configuring SQl and cluster services, these accounts will be given the correct permissions.

Question on IP Addresses for SQL Cluster

I'm adding new nodes to an existing SQL Cluster Win2k SP1 SQL 2000 Ent.
SP3a.
Was wondering if I am going to have a problem since the IP addresses of the
new nodes are on a different VLAN.
Old node, Cluster IP & Virtual SQL IP are on 10.28.1 The new nodes are on
10.28.17. These IP addresses are on two different VLANs. Same domain.
I've had so many problems with getting the new nodes to join the cluster and
failover, I wanted to check this out in advance.

There is a long technical explanation for why this can't work without
some serious reconfiguration of your system (router, switch & node
hardware), but the short answer is that the Cluster IP and the SQL IP
are static addresses. They cannot exist on a foreign network any more
than if you had separate physical networks instead of using VLAN tagging.
Save yourself (and your network admins) a boatload of trouble and make
sure that the nodes, cluster & SQL addresses are all on the same IP network.
