H06.27 Software Installation and Upgrade Guide

If you are upgrading from H06.16, create a subvolume to store the backups, then rename each
backup file after you create it. The default file name for the backup is backupgz. Rename these as
you create them. For example:
1. CLIMBKUP N100251 $DATA1.BCKH0616
2. FUP RENAME $DATA1.BCKH0616.BACKUPGZ, $DATA1.BCKH0616.N100251
3. CLIMBKUP N100282 $DATA1.BCKH0616
4. FUP RENAME $DATA1.BCKH0616.BACKUPGZ, $DATA1.BCKH0616.N100282
For upgrades from H06.17 and later RVUs, you can specify a unique filename in the same
command. For example,
>CLIMBKUP N100251 $system.N100251.BCKH0617
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 this 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.
