Restore Configuration Files
Restore your customized configuration files. This includes the group @.config, and the files nmconfig, nminit,
and hpswinfo.
1. Mount your backup or STORE tape from the release to which you are backdating. Refer to “Planning Your
Backdate” earlier in this appendix for additional tape information.
2. Type at the prompt.
:FILE T;DEV=TAPE
:RESTORE *T;@.CONFIG,NMCONFIG,NMINIT,HPSWINFO;OLDDATE;DEV=1
Configure the System
Refer to “Configuring the System” in Chapter 5, “Modifying Your System,” for additional information about
these steps.
You need to configure the following devices for AUTOINST (the update tool) to work properly:
•an LP device class
• a streams device
• a tape drive (that matches the FOS and SUBSYS media type)
If you need information about hardware device IDs, print the file IODFAULT.PUB.SYS on your screen. This file
contains ID numbers and associated parameters for hardware devices. You can display this file when the
system is up and you have the system prompt.
To configure your I/O and save the customized set of configuration files, perform the following steps:
1. Verify the configuration files.
:SYSGEN CONFIG
sysgen>
If you modified your configuration after updating to the latest Release, you must reenter these
modifications at this point. This includes I/O changes, and any modifications made to logging events,
system files (SYSFILE), or miscellaneous (MISC) items.
sysgen> KEEP
Purge old configuration? (yes/no)
sysgen> EXIT
If you do not have a backup of your old CONFIG.SYS group, modify your configuration manually as
described in Step 2. Otherwise, skip to Step 3.
2. Modify or restore configuration files.
a.
Type at the prompt.
:sysgen
