SOLUTION SUMMARY:
Booting /genvmunix under V4.0F recognized the Symbios SYM8952U
SCSI controller and my new disk. Then, rebuilding the kernel with
/usr/sbin/doconfig automatically makes the correct /dev/rz* device files
(with correct bus no, etc) and automatically updates the options in the
system config file, /sys/conf/HOSTNAME. A final reboot successfully ends
the procedure.

Subject: Adding a Symbios SCSI card and 2nd hard drive
Hi gurus,
Problem: I'm trying to install a new SCSI card (Symbios SYM8952U) and
second SCSI hard drive in my Compaq XP1000 running Digital UNIX V4.0F.
Current status/questions:
- I've installed the SCSI card and only one (internal) device, my new
hard drive, to the new card.
- A "show device" at the boot (>>>) prompt is able to correctly see
the new SCSI controller and disk.
- Darn, I don't see the new disk (automatically) detected in the startup
message.
- How do I make a special device file for this new disk? Specifically,
how do I get the correct parameters for the MAKEDEV command (bus no,
etc)? How do I set options to have my kernal recognize the new disk?
I'm still at the sysadmin level where I need detailed explicit examples!
Thanks in advance for any help you can lend,
Chong.

Step 1: Follow the directions in the system management guide for installing
new hardware in your system.
Step 2: Use your new hardware.
YOU MUST FIRST BUILD A NEW KERNEL WITH A DRIVER AND RELATED DEVICE DATA
STRUCTURES TO SUPPORT YOUR NEW SCSI CONTROLLER.
If you booted the /genvmunix kernel from the root partition, it would
probably see your new SCSI controller, and depending on which slot you
put it in, you might even be able to mount your system disk using the
existing name and build your new kernel. It's all documented in the
manual; read it.

Subject: Re: Adding a Symbios SCSI card and 2nd hard drive
Ignoring for a moment that the new SCSI adapter may not
be supported by the operating system...
Anytime you add an I/O adapter to a V4 and earlier system
you have to rebuild the kernel so that it will know to
look for the adapter and have the appropriate device
driver. There should be a section of the system management
documentation that explains how to do this. The short
version is:
1. Shutdown.
2. Boot /genvmunix:
>>>boot -fl s -fi "genvmunix"
3. Check and mount the local file systems.
# bcheckrc
4. Run doconfig to build new kernel:
# doconfig
5. Copy the new kernel to the root and reboot:
# cp /vmunix /vmunix.sav
# cp /sys/HOSTNAME/vmunix /
# reboot
Unfortunately, you can't ignore the fact that the new
adapter may not be supported. If the vendor included
a driver for Tru64 UNIX, then you probably just need to
follow their instructions for installing it. If they
claim that some driver of ours will work with it, please
remember that they're making the claim and not us, if
doesn't work. If they don't say anything on the subject,
be afraid.
One way to check is to watch the messages from booting
/genvmunix. If one of our drivers thinks it has
recognized the device, you should see some information
on it. I'll take a wild guess that our driver for the
KZPAA (psiop) will be the most likely driver to recognize
it. However, our driver is written and qualified for
our adapters, not random 3rd party that pretend to be
the same as the KZPAA. You may want to go through your
own qualification before you start trusting data to the
adapter.

When you add a new _card_ (as opposed to just adding a drive) you
need to boot the generic kernel and build a new system-specific
kernel. Building the new kernel will cause the correct devices to be
created in /dev.
Shut down the existing system.
At the boot prompt:
>>> boot -flags s -file /genvmunix
The system will come up to single-user mode. Now, to build the kernel:
# bcheckrc
# swapon -a
# update
bcheckrc mounts all local disks.
swapon -a adds all the swap spaces defined in /etc/fstab to the system's swap.
update starts the update process.
Now, to build the kernel:
# doconfig
This will prompt you with default name of the system config file,
which will match the hostname:
Enter a name for the kernel configuration file. [HOSTNAME]:
Press RETURN.
A configuration file with the name 'HOSTNAME' already exists.

The new kernel is /sys/HOSTNAME/vmunix

Now rename the old kernel and copy the new one into place as /vmunix:
# mv /vmunix /vmunix.old

Finally, reboot the system:
# reboot

Subject: RE: Adding a Symbios SCSI card and 2nd hard drive
Hello Chong,
You will have to build support into the kernel for the new device. After
the controller is built into the kernel the OS will create the device
special file at boot time.
>>> boot -fl s -fi genvmunix # Boot the generic kernel in single
user mode
# mount /usr # Mount /usr
# mount /var # Mount /var
# sizer -n new_config_file # Creates a configuration file in
/tmp/new_config_file
I would look for the scsi entries on the /tmp/new_config_file and compare it
to the scsi entries in your /sys/conf/HOSTNAME file (the HOSTNAME file is
your actual hostname in upper case). I don't have a SCSI card or system like
that else I would give the exact entry for the slot that it is plugged into.
Add the appropriate controller and bus entry for the slot your new card is
plugged into the rebuild the kernel.
# doconfig -c YOUR_SYSTEM_HOSTNAME # Build new kernel
# mv /vmunix /vmunix.orig # Save your old kernel in /
incase you need to boot it again
# cp /sys/ YOUR_SYSTEM_HOSTNAME/vmunix /vmunix # Copy new kernel to /
# shutdown -r +5 "rebooting new kernel" # Reboot in 5 minutes
The new controller and disk should show up during the boot.
If things do not boot properly you can boot your original kernel by doing
the following.
>>> boot -fi /vmunix.orig # If you renamed the original
/vmunix to /vmunix.orig
Good Luck,
Dan Willis

Hi
Any added controller requires booting from /genvmunix and rebuilding the kernel,
existing controllers in the kernel can auto recognize additional disks.

Of course not. Disks on built-in controllers will be recognized at boot
time, but a controller must be statically built into the kernel. So,
boot genvmunix and do a doconfig.
Then use MAKEDEV.

Subject: Re: Adding a Symbios SCSI card and 2nd hard drive
You need to rebuild the kernel after adding the disks.
1. Boot from /genvmunix:
>>> boot -fi "genvmunix"
2. Run doconfig which will automatically make the correct /dev/rz* files
and will add the correct bus and controller lines to /sys/conf/SYSTEM_NAME
in order to build the new kernel.
3. Save the old /vmunix kernel (e.g. as /vmunix.save) and copy the new
kernel to /vmunix
4. Reboot.
After that you should be able to mount your disks.

Hi,
Look at the startup messages (in /var/adm/messages) and check for the
mention of the new card.
Chances are the new card hasn't been configured into the kernel.
Best bet is to boot -fi genvmunix and let it run the automatic
reconfiguration. Your other option is to edit the config file to
add an entry for the new card and rebuild the kernel manually.
Your new disk will show up as device rzXX where XX is calculated by
(bus# * 8) + SCSI ID of disk. eg drive ID5 on bus 2 will be rz21.
If you need to manually create the special files just cd to /dev and run
MAKEDEV rzXX
Cheers
Joe
