Backdating Your System
Finishing Up
Finishing Up
To restart your system on the backdated version, perform all the sub-sections in this
section.
Configure Data Communication
Refer to “Configuring Datacomm and UPS” and “Cross Validating” in Chapter 6 ,
“Finishing the Process,” for additional information about these steps.
CAUTION No matter what your particular networking configuration is, whether you
even have networked devices, you still must perform the activities described
in this section.
You must convert the data communications configuration files after modifying a system
(regardless of whether you use data communications products). The information contained
in the data communication files is required by the Data communication Terminal
Controller (DTC) and allows communication between the terminal and the
Uninterruptible Power Supply (UPS). Refer to Using the Node Management Services
Utilities.
Convert Data Communications
To configure for data communications on a new or modified system, obtain an NMCONFIG
file in either way:
• Convert an existing nmconfig file to the MPE 5.0 or 5.5 version level you are
backdating to.
• Create an NMCONFIG file using NMMGR. Do this if you are using either Method 2, “Using a
factory SLT” or Method 3, “Using an FPT.”
To convert data communications files:
1. Confirm that you have a copy of the NMCONFIG file on your system.
:LISTF NMCONFIG.PUB.SYS
• If listed, and you do not need to create a new NMCONFIG file, proceed to Step 2.
• If the return message is non-existent file, obtain a copy of an NMCONFIG file
using one of the following sources:
— Create a new NMCONFIG file using nmmgr.
Refer to Using the Node Management Services (NMS) Utilities for directions on
creating an NMCONFIG file.
Then proceed to “Cross Validate” in the next subsection.
— Use a backup copy of the NMCONFIG file.
Use the same method, to recover the NMCONFIG file from the backup, that was
