H06.12 Software Installation and Upgrade Guide

Back Up TMF Files
Use the OBEYFORM option available in TMFCOM INFO commands to save current configuration
information in command files.
Record the Current SYSnn
Identify and record the current SYSnn subvolume on your system. You will have to specify this
SYSnn subvolume if you need to fall back from the H06.12 RVU.
At a TACL prompt, issue the status command to determine the current SYSnn subvolume. For
example:
3> status 0,0
System \ELI
Process Pri PFR %WT Userid Program file Hometerm
0,0 201 P R 000 255,255 $SYSTEM.SYS01.OSIMAGE $YMIOP.#CLCI
Swap File Name: $SYSTEM.#0
Save the Current Configuration File (CONFxxyy)
A saved system configuration file contains a copy of the current configuration database CONFIG
file, saved for future use. For fallback purposes, save a copy of the current CONFIG file by using
a unique file name. Do not omit this step.
You can use the saved configuration file to return to an earlier, stable configuration. If you need
to fall back to the previous RVU, you must load the system by using a saved configuration file
and the SYSnn containing the previous operating system.
To save the current system configuration database CONFIG file, use the SCF SAVE command:
1. At a TACL prompt, start SCF:
12> SCF
2. List the saved configuration files. At the SCF prompt, enter:
-> FUP INFO $SYSTEM.ZSYSCONF.CONF*
3. Save the current configuration by using a unique file name. At the prompt, enter:
-> SAVE CONFIGURATION xx.yy
where xx.yy is a number from 0.0 through 99.99.
This example saves the current system configuration to the file $SYSTEM.ZSYSCONF.CONF1101:
-> SAVE CONFIGURATION 11.1
The configuration file $SYSTEM.ZSYSCONF.CONF1101 has been created.
