.What Happens at Normal System Load

is the one-digit number that identifies whether the G4SA or FCSA is installed in

module 2 or 3 of an IOAM. A module is either 2 or 3.

is the one-digit physical slot number in the IOAM. Numbers range from 1 to 5

is a number that indicates the order in which the process was configured.

pif

is the physical interface (PIF). Adapter ports and “PIFs” are interchangeable terms.

A PIF is part of the SLSA subsystem and represents the physical port on the

adapter. An adapter has four PIFs: A, B, C, and D.

.What Happens at Normal System Load

Normal system load occurs when you want to load the system using the existing

CONFIG file. The steps are as follows:

1. Start the system from a system console, specifying the CONFIG current system

configuration file on the $SYSTEM.ZSYSCONF subvolume.

2. When the system starts and displays a TACL prompt, you can log on and start the

rest of the system applications.

Returning to a Saved Configuration

You can load an earlier version of the system configuration database by specifying a

saved version of the CONFIG file. You can use this method to switch quickly to an

alternate configuration (for example, if you use different configurations for day or night

operations). Or you can use this method to recover from a configuration change that

caused a problem (for example, a system freeze). The steps are as follows:

1. Load the system from a system console, specifying a saved version of the system

configuration file, in the form

xx.yy

. For example, the CONF0205 file would be

specified as 02.05 in the OSM dialog box. (Entering just 2.05 or 2.5 will also work.)

2. When the system starts and displays a TACL prompt, you can log on and start the

rest of the system applications.

3. Enter an INFO SUBSYS $ZZKRN command to verify that no pending changes to

system attributes are displayed. If the display erroneously shows any pending

Note. When you attach NonStop S-Series I/O enclosures to Integrity NonStop NS-series

servers, the naming conventions described in the
