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.
1. Before Halting the Processors
A. When Upgrading From an H06.15 or Earlier RVU: Modify OSSINFIL
When upgrading from an H06.15 or 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
Then change
SERVER #ZPLS
to
* SERVER #ZPLS
Failure to do this can result in an error during startup of OSS. This error occurs on systems with
pre-T0585H01.
