H06.15 Software Installation and Upgrade Guide

5 Preparing to Upgrade the Server Software (Pre-installation
Tasks)
This chapter describes tasks that are needed before updating the system console and receiving
the SUT.
Back Up Important Files
Before you upgrade, create tape back-ups of critical host applications and files.
Back Up NonStop SQL/MP
HP recommends that you always have a current backup copy of the $SYSTEM.SYSTEM.ZZSQLCI2
file in case you need to initialize SQL later if you have problems with your new RVU during or
after installation.
1. Save a copy of the existing ZZSQLCI2 file on the $SYSTEM disk. For example:
> FUP DUP $SYSTEM.SYSTEM.ZZSQLCI2,$SYSTEM.BKUPZSQL.*, SAVEALL
2. Enter:
> SQLCI INITIALIZE SQL; EXIT;
3. Copy the ZZSQLCI2 file saved previously back to the $SYSTEM disk. For example:
> FUP DUP $SYSTEM.BKUPZSQL.ZZSQLCI2, $SYSTEM.SYSTEM.*, SAVEALL
Back Up NonStop SQL/MX files
See the NonStop SQL/MX Installation and Management Guide.
Back Up Spooler Control files
Before executing the SPOOLCOM;SPOOLER,DRAIN command:
• Use the SPOOLCOM;COLLECT $collector-process, LISTOPENS command to identify
processes that currently have jobs open.
• Use the SPOOLCOM;JOB (STATE PRINT) command to determine which jobs are currently
printing.
Take the appropriate action to ensure that these jobs either terminate when finished or are stopped.
CAUTION: To maintain the integrity of the spooler environment, wait until the spooler has finished
draining rather than stop any spooler processes by using the TACL STOP command. The control
file can be corrupted during the next warm start or rebuild.
An example of backing up the spooler control files:
BACKUP/OUT SPLBKUP/$TAPE,($SYSTEM.SPOOLER.*,$DATA01.SPOOLER.DATA),LISTALL
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 this RVU.
At a TACL prompt, issue the status command to determine the current SYSnn subvolume. For
example:
