3. Make any desired changes from the IO, LOG, or MISC configurators.
Refer to Chapter 5 , “Modifying Input/Output (I/O) Configurations,” and Chapter 7 ,
“Modifying Miscellaneous Configuration Elements,” for information on using the IO,
LOG, and MISC configurators to alter the system configuration.
4. After completing any changes, but before exiting a configurator, enter:
HOLD
The HOLD command saves changes (to a temporary file) made in the configurator at the
time that the HOLD is issued.
5. Decide which files to dump to tape.
SYSGEN allows you to choose which files to store to a boot tape. You may store autoboot
images, boot images, and system programs.
The SYSFILE configurator provides the utilities and commands that alter boot tape
contents. For information on the commands available for adjusting boot tape contents,
refer to Chapter 8 , “Modifying System File Configurations.”
6. Hold any changes made in step 6.
After completing any changes, but before exiting the configurator, enter:
sysfile>HOLD
7. Exit the SYSFILE configurator. Enter:
sysfile>EXIT
8. Issue the KEEP command to store all changes to a set of permanent disk files by
entering:
sysgen>KEEP
groupname
9. Mount a write-enabled tape on the tape drive.
When you mount the tape on the tape drive, the system issues a message similar to the
following:
10:15/10/Vol (unlabeled) mounted on LDEV# 7
10.Generate the tape.
• To create only a system load tape (SLT), enter the following command:
sysgen>TAPE
This is a tape containing the operating system and specified configuration
information.
