SUMM: Adding a disk drive

Thanks to all. We finally figured out what we had done wrong -- we had the
new drive in rrz9, NOT 10!! (Yes, we do have two controllers). I warned you,
it was stupid!

I received many, many useful suggestions. Dr. Tom Blinn, our faithful DEC
contributor, was the one who figured it out. Thankfully, we saved some face
by figuring it out before we heard from Dr. Blinn (our internet connection
was down, so we couldn't get messages, but could still play with our Alpha).

In the interest of helping someone with disk drive problems who is searching
the archives, I have included the answers below as a trouble-shooting guide.

I believe the "rz" device type is for SCSI devices. And
the "10" refers to a SCSI device ID the disk drive is set to.
"Normal" SCSI devices can have ID from 0 to 7. So unless you have some
very special hardware, you must be mistaken about the device ID

You have to use the following command:
disklabel -rw /dev/rz10 rz29

You have to specify the disk model.

Did you add the device entry into the system configuration file in /sys/conf
and rebuild the kernel? The other way to do it is to boot up from the
generic kernel and have it do an autoconfig and create a new configuration
file and rebuild a new kernel. (I assume you must already know that rz10
means that the disk should be set to target ID 2 on the second SCSI bus.)

good luck,

High, Sheryl,

you wrote:

        disklabel: /dev/rrz10a: No such device or address

I would think it should look like this:
 
        % ROOT admin::/dev> disklabel -rw rz10c rz29
                                              ^

Hope this will help you.

I like your homepage. It's very friendly. Hope my own will also look good one

Hi Sheryl,

                You are almost there!

                The correct use of the disklabel command is:

                 disklabel -rw /dev/rrz10a rz28

                 disklabel -e rz10 ! to list the partition
table on the disk.

                 Then newfs the partition/s you want to use (c for
                 the whole disk or a selection of others to split
                 the disk into "segments").
             
                 newfs /dev/rz10c

                 Create a mount point: mkdir /usrx

                 mount the disk: mount /dev/rz10c /usrx

                 Enter the mount command into the /etc/fstab file for
                 automounting on boot up.

                 The last parameter in the disklabel command must
                  be a recognised disk type from the /etc/disktab
                  file.

                  best regards,

                  John Welsh.

Try

# scu show edt

to find out the correct scsi address, then use MAKEDEV to create the right ones.

Hi,

  The new drive is almost certainly not included in the kernel
 configuration file - "/sys/conf/<machinename>". You will have to
 edit this file to add the new drive and then rebuild the kernel
 using "doconfig -c <machinename>". You can look in the file
 "/sys/conf/GENERIC" for examples or use the command "sizer" to
 generate a new file.

 Alan

As long as you haven't added the disk to a new controller Digital Unix
should be very able to probe and register any new drives on an known
controller. I guess that a defective drive also might get disabled
upon boot and produce this kind of confusedness. So much for natural
causes.
If the above requirements are met, I cannot think about very many
options in the "stupid" category, but here's one:
Are you sure that this drive gets recognized as rz10 and not somethnig
else? With MAKEDEV you can create device files for anything - even if
isn't even present on the system.
Take a look at (the end of) /var/adm/messages and you should probably
find the answer to that and to the question of wether the disk gets
recognized at all.

Hi Sheryl,
You gave the command as:
	disklabel -rw rz10 scratch1
I've believe it should be:
	disklabel -rw /dev/rrz10c rz29
That should work.

You don't say what kind of alpha, or what version of the OS. Versions 3.2
require adding lines to the kernel config file to see drives; versions 4.x
will dynamically
recognize the disk on boot and do the MAKEDEV for you.
Also, if you're using a StorageWorks array, sometimes they are in a split
bus mode, where
the numbers are not what one expects....
If you send me the console level stuff, and the uerf -R output showing
the boot messages, I can offer more ideas, perhaps half-baked :-)

     Hi Sheryl:
     
     After the disk instalation you have to define the device in 
     /sys/conf/HOST file and run doconfig -c HOST command. Copy the new 
     vmunix created at /sys/HOST directory to / (root) and reboot with 
     shutdown -r now.
     
     If you want to create file systems you can do it with :
     disklabel -er rz10 command. 
     
     To create filesystems use :
     newfs /dev/rrz10c rz29 command (rrz10c is an example to create c 
     partition )
     
     To mount the filesystem you have to create the mount point directory, 
     for example, mkdir alpha;  and finally  mount  /dev/rz10c /alpha 
     command.
     
     Oh, something else! ... you have to include the new filesystems in 
     /etc/fstab file to mount them at future reboots. 
     I hope this be helpful for you.

Everything you've done looks right.
What version of Digital UNIX?
What does # file /dev/rrz10a tell you?
What does # file /dev/rrz10c tell you?
If you're running V4.0x, when you booted the system, did it find the disk at
that address during probe?  That is, was the device reported in the list of
devices?
And rz10 would be on your second SCSI bus -- do you have two controllers?
Are there any other devices on that controller that work?  If this is a wide
drive, you need to understand that even with wide drives, all the drives
have to be at unit numbers below 8 -- only 0-7 work, if you've got a wide
drive set to a higher unit number, Digital UNIX won't be able to find it or
use it, even if the console sees it.
