INFORMATION RELEASE AB 180
TO ADVISE OF CHANGES FOR UNIX SVR4 03.02.
RIO
RIO driver V1.0.3 is now available for general release. This release is targeted at unix operating system 03.01 or better ie 03.02.
It will not load onto a previous version.
Prior to installation existing drivers must be removed using pkgrm rio.
To load RIO V1.0.3
Note:- Ensure current HOST/RTA settings are recorded.
Login : root <cr>
Password <cr>
pkgadd -d diskette1 rio <cr>
Load rio unix svr4 driver version 1.0.3 diskette into 1.44mb flex drive
Type "go" when ready <cr>
Rio installation will start, no further user interaction is required. The kernel will be rebuilt automatically.
IMPORTANT:- Do not reboot the system when prompted. A file will need creating before a reboot. Make sure all RTA's are connected.
NCR SVR4 3.02 has a fast boot feature. It appears that this new boot sequence is so fast that RIO RTA devices are unable to download fast enough. This is apparent because none of the RTA lights will be lit after the reboot.
The resolution is to create a new file in the directory /etc/rc2.d :-
cd /etc/rc2.d <cr>
vi S82edsleep <cr>
i to insert
sleep 20
To save file, ESCAPE :wq!
Now reboot the system
Shutdown -y -i6 -g0 <cr>
Login: root <cr>
At # config.rio <cr>
Setup RIO HOST/RTA's from the configuration recorded earlier.
The standard VDU/PTR cable specification for use with RTA's and RIO driver version 1.0.3.

In the /etc/ttydefs file the clocal entry requires amending. Move clocal from the start of the TTY label to the end.
See attached /etc/ttydefs printout.
TUNING
It is now necessary to change two tunable parameters, ufsninode, and vx_ninode.
Standard settings are :- UFSNINODE 2500
VX_NINODE 10000
Setting these standard parameters have caused a problem, the console displays:-
WARNING: htydrv.c: ntyIocbIsr Iocb error
The resolution is to tune the parameters :-
/etc/conf/bin/idtune -m ufsninode 1000 <cr>
/etc/conf/bin/idtune -m vx _ninode 5000 <cr>
/etc/conf/bin/idbuild <cr> rebuild kernel.
Shutdown -y -i6 -g0 reboot system
To verify updates have taken place, in root
pg /etc/conf/cf.d/stune <cr>
FDUMP
Unix svr4 3.02 on some NCR systems have displayed problems with initialising the dump configuration. While the system is booting error messages will appear:-
** Not enough dump space allocated**
** Powerfail strategy has changed to powerfail shutdown**
The resolution is to add a line to :-
/etc/rc2.d/S99DUMPCHK
Add a line fdump -i to the start of the file, directly below the comment lines.
