Adding a Peripheral to Any System
Adding a disk drive, tape drive, or printer to a system's configuration
includes the following steps:
* enter SYSGEN
* view the system's current configuration
* activate the IO configurator
* make the necessary I/O configuration changes
* hold the changes
* save the changes
* verify the accuracy of the new configuration
1. Activate SYSGEN's global module.
Enter the SYSGEN command at the system prompt.

2. Select the base group to modify.
If you desire to modify the default configuration groups, copy the
groups to other group names and modify the copies using the IO
configurator. Copying the groups preserves uncorrupted versions
of the default or current configurations.
To copy configuration groups, use the BASEGROUP command to
activate the desired configuration group. Use the KEEP command to
save the group of files to another group name. Refer to Chapter 4
for more information on using the BASEGROUP and KEEP commands.
After deciding which copied configuration group to modify, use the
global module BASEGROUP command to activate the group:
sysgen>BASEGROUP groupname
Use the I/O configuration contained in CONFG935 as an example
configuration for this exercise.
3. Activate the IO configurator.
Enter the global module command, IO, at the SYSGEN prompt to
activate the IO configurator:

| oclose (oc) redo |

4. Obtain I/O configuration listings.
Enter LCLASS, LDEV, and LPATH, at the IO configurator prompt to
get current I/O configuration listings:
io>LCLASS DEST=OFFLINE
io>LDEV DEST=OFFLINE
io>LPATH DEST=OFFLINE
io>OCLOSE
The OCLOSE command closes SYSGEN's listing file, SYSGLIST, and
prints the information in the file.
Refer to Chapter 5 for more information on using the LCLASS,
LDEV, LPATH, and OCLOSE commands.
5. Decide on which LDEV to add the drive.
View the LDEV command output. Choose any unused LDEV and consider
assigning it to the disk drive. For this example, use LDEV 4.
6. Decide on the class of the added peripheral.
View the LCLASS listing. If it contains a class (DISC) assigned
to a particular type of peripheral (in this case, a disk drive),
use that class for your addition. Remember, each device can
simultaneously belong to up to eight classes.
If your configuration does not contain a class name for the
additional peripheral, the system will create a class name for you
if you use a name that does not exist. Class names may not exceed
eight characters and must begin with an alphabetic character.
7. Add the path.
Since you are adding the drive to a newly installed HP-IB card,
you must define the path down to the device adapter level. Use
the APATH command to define the path.
For example, add the drive to a newly installed HP-IB card (ID
number, HP27113A). The HP Service Representative who installed the
card placed it in the CIO expander (CA 36) on channel adapter 2,
and device adapter slot 2. Enter:
io>APATH 36.2 HP27113A
Refer to Chapter 5 for additional information on using the
APATH command.
8. Add the device.
Use the ADEV command to add the device, including the device
address, to the path specified with the APATH command. Enter:
io>ADEV LDEV=4 PATH=36.2.0 ID=HP7937H CLASS=DISC
Refer to Chapter 5 for additional information on using the
ADEV command.
9. Hold all changes.
Enter the IO configurator HOLD command at the IO configurator
prompt:
io>HOLD
Refer to Chapter 5 for additional information on using the
HOLD command.
10. Exit the IO configurator.
Enter the EXIT command at the IO configurator prompt:
io>EXIT
sysgen>
11. Save changes in a permanent file.
Enter the global module KEEP command at the SYSGEN prompt:
sysgen>KEEP CONFIG
CONFIG is the group name under which you save the modified files.
Each time you start up the system, the group CONFIG will then be
the default.
Refer to Chapter 4 for additional information on using the
KEEP command.
12. Generate a boot tape.
Mount a write-enabled tape on the tape drive. Enter:
sysgen>TAPE
The system may place a tape request similar to the following:
?11:10/#S1/46/LDEV# FOR "SYSGTAPE" ON TAPE (NUM)?
If this message appears, respond:
CTRL A
=REPLY pin,7
where pin is the PIN (in this instance 46) from the third location
in the tape request.
After all the files are stored, unload the tape, and write protect
it. Label the tape, and store it, in a secure location, with any
other backup materials.
13. Exit SYSGEN and reboot the system.
sysgen>EXIT
NOTE Any disk device smaller than 400 Mbytes should not be installed as
the system disk (LDEV 1). A disk this size or smaller is too small
to run the operating system and its subsystems. A 400-Mbyte or
smaller disk, however, can be used as any other LDEV.
In this procedure, the system manager chains (configures) a tape drive to
another configured device, (commonly referred to as a host device). The
host device doesn't have to be physically attached to the system to
configure the tape drive but when the tape drive is connected, the host
device must be present.
