Install the primary and the secondary servers in the same location on each node. The primary companion can be either a newly installed Adaptive Server, or it can be upgraded from an earlier version of Adaptive Server with existing databases, users, and so on. The secondary companion must be a newly installed Adaptive Server and cannot have any user logins or user databases. This is to make sure that all user logins and database names are unique within the cluster.
After configuration for failover is complete, you can add user logins and databases to the secondary companion.
If you are installing on the local disk, make sure any databases are created on the multihost disk.
See the installation documentation for your platform for information about installing and configuring Adaptive Server.
