Configuring the Modular Tape Subsystem Online Using SCF
On NonStop Himalaya S-series servers, you use the Subsystem Control Facility
(SCF) to configure tape drives. SCF allows you to add, change the attributes of, and
delete a tape drive. You can run SCF from any terminal on the system after you are
logged on. Using SCF, you can:
•
Obtain configuration information about a tape drive
•
Restore access to a tape drive
•
Stop access to a tape drive if there is no activity
•
List tape drive status
•
Switch the primary processor for a tape drive
This subsection provides examples of configuring cartridge tape drives using SCF.
The examples show how to define and add a tape drive to the system configuration,
alter the attributes of a tape drive, and remove a tape drive from the system
configuration. For a complete description of how to configure and manage tape drives
using SCF, see the SCF Reference Manual for the Storage Subsystem.
For information about how you use SCF to configure, control, and inquire about other
supported subsystems for NonStop Himalaya S-series servers, see the SCF Reference
Manual for G-Series Releases.
Example 1: Defining and Adding a Tape Drive
You use the SCF ADD TAPE command to define and add a 5190 or 5194 tape drive to
your system configuration.
Before you issue the ADD TAPE command, check that the tape drive is installed
properly (see Section 3, Installing the Modular Tape Subsystem or to the Himalaya
S-Series Hardware Installation Guide). Verify the group enclosure, module, and slot
that the tape drive is connected to (see Identifying CRUs on page 2-19).
The following example adds tape drive $TAPE0 to the system configuration:
->ADD TAPE $TAPE0, SENDTO STORAGE, LOCATION (2,1,55),&
->&PRIMARYCPU 0, BACKUPCPU 1
The following are notes about this example:
•
The LOCATION attribute specifies the location (group,module,slot) of the CRU to
which the tape drive is attached.
•
The PRIMARYCPU attribute specifies the processor in which the primary tape
process should execute.
•
The BACKUPCPU attribute specifies the processor in which the tape process
starts its backup process.
