Active Passive to Active Active

Hi ,
Can we convert the Active passive cluster to Active Active mode .
Please advise .
Thanks
ARR
Its not really a conversion per se. You can install up to 16 instances per
SQL cluster.
Cheers,

|||Hi
With SQL Server 2000, Active/Active or Active/Passive is just a term used to
describe the server, and not a setup limitation.. By adding the necessary
recourses, such as file disk groups, you can turn an A/P into an A/A.
If you currently have a instance with 3 drives (E, F, and G), to create
another instance, you can not use those drives, so you need to get more
volumes on your SAN for H, I, J etc.

|||Hi ,
Thanks for the reply .
Any other steps tobe done while installing instance on other volumes or if
we install other instance whether it will run on other node by default .
My assumption is on both node two different instances will run after adding
one more instance .
Thanks

|||Except for the actual installation process, all cluster nodes in SQL 2000
are equivalent. During the installation, you run the install app from the
node that currently hosts the disk resource you intend to base the SQL
instance on. You can set the allowed and preferred hosts for each SQL
resource group independently after installation. Be sure to test running
with both instances on one node because that is what will happen during a
failure.
