J06.12 Software Installation and Upgrade Guide

You can configure additional alternate system disks. To create an alternate system disk, contact
your HP authorized service provider to perform the task. Then use OSM to make the disk available
in the Configuration drop-down menu in the System Load dialog box. The alternative system disks
are displayed in the Attributes tab under the System object in the OSM Service Connection and
are also displayed in the OSM Low-Level Link System Load dialog box in the Configuration shortcut
menu.
Alerts
Before performing a system load:
• Before halting the processors, stop applications that are still running, including TMF.
NOTE: To stop TMF, at a TACL prompt, enter:
TMFCOM STOP TMF
The NonStop Operations Guide contains detailed information on the best methods for stopping
applications, devices, and processes.
• Ensure that sufficient swap file space is available for the installation. Either use NSKCOM to
ensure that there is at least one KMSF swapfile on $SYSTEM for each of CPU 0 and CPU 1,
or ensure that there is more than 40MB of free space on $SYSTEM.
There are several ways to create additional free space on $SYSTEM, including:
◦ Delete all existing zlog*.* files
◦ Delete all existing *.zzsa* files
• Do not close the System Load Startup dialog box while startup is in progress. If you attempt
to close the dialog box, a message dialog box appears notifying you that the system startup
process will be stopped if you continue.
• If you stop a system startup before it has finished, the state of your system will be unpredictable.
You might need to perform another system startup to enable the system to resume normal
operation.
• If you must stop the system startup process, click Abort. (The abort process should take effect
within 30 seconds.)
• In the System Load dialog box, either select all four disk paths, or check that the selected disk
path is correct. If you do not select all four or select the incorrect disk path, the system does
not load properly.
• If you have problems performing a system load, see the NonStop Operations Guide, Chapter
15.
Perform Updates
1. Before Halting the Processors
Before halting the processors on your system, perform these actions as needed.
Perform Required RVU-Specific Upgrades
When Upgrading From J06.04 or an Earlier RVU: Removing #ZPLS
When upgrading to this RVU from J06.04 or an earlier RVU, before halting the processors, you
must remove the SERVER #ZPLS entry from the OSS subsystem maintenance file OSSINFIL on all
systems with OSS installed. The simplest way to do this is to use the TEDIT utility to change the
SERVER #ZPLS entry to a comment, as follows:
TEDIT $SYSTEM.ZOSSINS.OSSINFIL
