System Startup, Configuration, and Shutdown Reference Manual (32650-90892)
Appendix F 225
Adding Peripherals to a System
Adding a Peripheral to Any System
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 PCI SCSI 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 PCI SCSI card (ID number, A5150A).
Enter:
io> ap 1/0/0/0 id=A5150A
Refer to Chapter 5 , “Modifying Input/Output (I/O) Configurations,” 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 14 1/0/0/0.6.0 ST39103LC class=(DISC,SPOOL)
Refer to Chapter 5 , “Modifying Input/Output (I/O) Configurations,” 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 , “Modifying Input/Output (I/O) Configurations,” 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 , “Using the System Generator (SYSGEN),” for additional
information on using the KEEP command.
12.Generate a boot tape.
Mount a write-enabled tape on the tape drive. Enter:
