The order of statements is not important, except:
°
An ADD statement depends on preceding SET statements.
°
An ADD statement implicitly resets all preceding SET statements.
CONFIG^FILE
CONFIG^FILE is a TACL variable containing the name of a Nomadic Disk configuration
file:
•
If the variable CONFIG^FILE exists when you start the Manager and it is not blank,
the Manager assumes the variable contains a file name and attempts to open and
interpret that file.
•
If the variable CONFIG^FILE does not exist or if it is blank, then the default
configuration file is used. The default configuration file is
$SYSTEM.NOMADIC.NDCONFIG; however, this file name can be changed.
To change the default CONFIG^FILE, refer to Example 3-1, Sample TACLCSTM File
Included with the Nomadic Disk Manager, on page 3-4 .
Configuration File Examples
The following are example NDCONFIG files for a basic configuration for each of the
two nodes participating in a ServerNet Nomadic Disk configuration. For detailed
descriptions of all configuration statements, see
Nomadic Disk Manager Configuration
Statements on page 3-8.
In a normal state, the node \TELE is the primary node and owns the Nomadic volumes
and \OMS1 is the backup node. Each node contains:
•
An I/O enclosure equipped with 16 internal 46xx disk drives.
•
One switch module containing two switch cards and two RS-232 ports. One port of
the switch module is connected to the primary node and the other port is
connected to the backup node. The switch module devices are named $SM01.#A
and $SM02.#A. Each node has both a $SM01.#A and $SM02.#A device; they are
configured as local devices, even though one of the switch modules resides at the
remote site.
°
Switch module device \TELE.$SM01.#A refers to one of the ports on the switch
module that resides at the \TELE site; \TELE.$SM02.#A refers to one of the
ports on the switch module that resides at the \OMS1 site.
°
Switch module device \OMS1.$SM01.#A refers to the second port on the
switch module that resides at the \TELE site; \OMS1.$SM02.#A refers to the
second port on the switch module that resides at the \OMS1 site.
