Configuring the Modular Tape Subsystem Online Using COUP
On NonStop Himalaya K-series servers, you can use the Configuration Utility
Program (COUP) to configure a 5190 or 5194 cartridge tape drive dynamically—that
is, without having to create a new system image and load it. COUP is the user
interface to the Dynamic System Configuration (DSC) utility. COUP allows you to
change some parts of your system configuration online, reducing the need to stop
system operations to reconfigure. If you are a member of the super group (255,n), you
can use COUP to perform online I/O reconfiguration from any connected terminal.
Using COUP, you can:
•
Add or delete objects (such as a 3216 controller or a 5190 tape drive) in the
system configuration
•
Stop the I/O process for a tape drive
•
Alter the characteristics of a tape drive
•
Start the I/O process for a tape drive after altering its characteristics
•
Obtain information about the current configuration
Always use the product code 5190 when configuring either the 5190 or the 5194 tape
drive with COUP.
This subsection provides examples of configuring tape controllers and cartridge tape
drives using COUP. The examples show how to define and add a controller and tape
drive to a system configuration, start the tape drive, and remove the tape drive from the
system. See the Dynamic System Configuration (DSC) Manual for a complete list of
supported devices and for more information about COUP.
Caution. Before using COUP, always make backup copies of your original OSIMAGE and
OSCONFIG files. If you wish, create a log file of the COUP session so you can update the
CONFTEXT configuration file the next time you do a system generation.
