together with TrueCopy Asynchronous for Mainframe or Continuous Access Journal Z. The
information collection interval for the Usage monitor must be 10 minutes or less.
NOTE: If a Continuous Access Journal Z copy group that contains XP24000, XP P9500, or XP7
volumes, start the Usage monitor of the control unit to which the journal volume belongs in order
to acquire correct information.
Settings in the Set Defaults panel
This section describes the items below, which need to be initially configured in order to use Business
Continuity Manager. You can specify these items in the Set Defaults panel, which is displayed from
the Main Menu panel. To use Business Continuity Manager, you first need to specify the DAD ID
and the prefix.
Specifying the device address domain ID
A device address domain (DAD) is a user-designated set of volumes that is accessible from a host
on which Business Continuity Manager is running. Each device address domain is identified by
its unique device address domain ID.
Define device address domain ID from the Set Defaults panel that is displayed when you select 1
Set Defaults in the Main Menu ISPF panel.
When you define a copy group that involves volumes on different sites, use the Local Device Address
Domain ID in the Set Defaults ISPF panel to assign a unique device address domain ID (DADP or
DADS in these examples) for each site.
Once you specify a device address domain ID for the primary site in Business Continuity Manager
(DADP for these examples), Business Continuity Manager can directly manipulate the volumes at
the primary site.
Figure 68 (page 120) shows an example of defining a device address domain ID.
Figure 68 Example of defining a DAD ID (for Cnt Ac-S Z, TCA, or Cnt Ac-J Z)
The device address domain ID specified for an NG scan is called a Non Gen'ed device address
domain ID. When executing an NG scan to acquire device configuration information, specify a
unique Non Gen’ed device address domain ID.
NOTE: A Non Gen'ed device address domain ID for an NG scan cannot be specified as a
device address domain ID in the route.
Figure 69 (page 121) shows the relationship between device address domain ID and Non Gen'ed
device address domain ID.
