Adding or Moving Hardware After Installation

The process of running swinstall to install the ACC product creates the
loopback configuration file /opt/acc/cfg/loopback.answ, based on the
location of the ACC card(s). Adding or moving ACC cards after software
installation will affect the correctness of ttgen configuration files. Refer
to "Loopback Configuration File" on page 46 for more details.
If any ACC Mux cards are added or moved within the system, you should
create a new loopback ttgen configuration file as described in the section
"Installation Verification" on page 38. This file can then be used as a
template for updating the mux statements in other ttgen files.
Once a ttgen configuration file is modified, then ttgen must be run on
that file and zmon must be restarted with the new .tmem file. (See
"Creating a ttgen Configuration File" on page 56 in Chapter 3, "Protocol
Configuration," for more information.)
A device file is needed to access a ACC Mux card. During system startup,
zmon verifies every hardware slot specified in the ttgen configuration
file. If a valid ACC Mux card is found, zmon automatically re-creates the
ACC Mux device file for that hardware location. Re-creation of device
files is necessary because the HP-UX kernel may assign a different
device major number to the ACC subsystem during system bootup.
Hence, existing ACC device files may become invalid after system reboot.
Before attempting to start up the ACC subsystem, you must first modify
the TTGEN .answ file and run TTGEN to create a .tmem file.
