By default, master is the default device in a newly installed Adaptive Server. This means that, any databases (including the proxy databases used by failover), are automatically created on the master device. However, having user databases on the master device is more difficult to restore from a system failure. To make sure that the master device contains as few user databases as possible, create a new device using disk init. Use sp_diskdefault to specify the new device as the default before you configure Adaptive Server as a companion for failover.
For example, to add a new default device named money_default_1 to the MONEY1 Adaptive Server, enter:
sp_diskdefault money1_default1, defaulton
The master device continues to be a default device until you specifically make it a non default device:
sp_diskdefault master, defaultoff
See the Adaptive Server Reference Manual for more information about disk init and sp_diskdefault.
