Important Installation and Configuration Notes

Adding or Moving Hardware After Installation

When the ACC and X.25/ACC products are installed on the system, there are files that are customized or created based on the current location of the ACC multiplexer cards. In the case that any ACC mux cards are added to the system or moved within the system, these files may need to be changed:

Create the appropriate device files, /dev/zx25mXpY for 2/8-Channel card, or /dev/zx25mXpYsZfor T1/E1 4-Channel card.
The device files that are used by the X.25/ACC product and that correspond to the hardware that is currently installed on the system can be created by running:
% /opt/acc/lbin/make_n2z_devs
A device file is created for each port (and sub-channel, if Z7300A or Z7330A) of each mux that is currently installed on the system. The X represents the mux number (i.e. 0, 1, 2, etc.). The Y represents the mux port (i.e. 0 through 7). (The Z represents the sub-channel number if Z7300A). Refer to Appendix C “Utilities, Servers, and Scripts” for more information on creating these files.
Create a new loopback ttgen configuration file. This can be used as a template for creating or modifying the actual ttgen files that will be used.
To create the sample loopback configuration file:
% cd /opt/acc/cfg
% /opt/acc/lbin/acc_bld_lpbk -o x25_loop.answ \
-t sample_header -p x25
To run ttgen on this configuration file:
% /opt/acc/bin/ttgen -o x25_loop.answ x25_loop.tmem
ttgen: END$ 0 Disasters, 0 Errors, 0 Warnings
%
Repeat step 2 to create a sample x25_loop configuration file, substituting the filename x25_loop.[answ | tmem] where appropriate.

Relocating the EISA Mux Card




	NOTE: When an EISA ACC multiplexer card has been installed and is subsequently removed for re-installation into a different slot, the eisa_config program will prompt with the following message after the system reboots:

eisa_config running in automatic mode to fix a configuration mismatch
Date: 02/12/96   09:50:40
 
One or more of the EISA boards that are listed in the configuration
are no longer responding.  There are two possible causes:
 
    (1) The board has been removed.
    (2) The board is no longer responding because of a hardware problem.
 
The board(s) listed below are not responding:
    Slot <n>
 
eisa_config finished

Use the eisa_config program to correct this problem:

$ eisa_config
 
EISA: remove <n>
 
EISA: q

You must type “s” next, to save the change to the configuration.




	NOTE: Before attempting to start up the ACC subsystem, you must first modify the TTGEN .answ file and run TTGEN to create a .tmem file.

Using other X.25/9000 cards and ACC cards together

The X.25/ACC product running on an ACC card may not be used in the same system as other interface cards supported by the X.25/9000 product at this time.

Installing Other Products

The scripts which configure the ACC and X.25/ACC products during the swinstall process modify these files:

/etc/services

These files may be updated when patches or other products are installed on the system, including those that are not related to the ACC product. If this occurs, this may cause the mk_kernel of the system to fail, typically due to unsatisfied symbols or /etc/services not containing the proper entry for znode.

If this appears to be the case, the configuration procedure can be re-run as follows:

% swconfig -x reconfigure=true ACC.ACC-RUN
 
% swconfig -x reconfigure=true ACC-X25ST.ACC-X25ST-KRN

After performing this procedure use mk_kernel to rebuild the kernel, move the new kernel image file into place (/stand/vmunix) and then reboot your system.
