master is the default device in a newly installed Adaptive Server. This means any databases you create (including the proxy databases used by failover), are automatically created on the master device. However, adding user databases to master makes it more difficult to restore the master device 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 money_default1, defaulton
The master device continues to also be a default device until you specifically issue the following to suspend it as the default device:
sp_diskdefault master, defaultoff
See the Adaptive Server Reference Manual for more information about disk init and sp_diskdefault.
