10.20 install on D380/2

[Fred Martin_1]

I have a D380/2 with 5 physical disks installed.

If I interrupt the boot, and have it search for devices, it lists 10 disks not 5.

Also, if I try to install 10.20 by booting from the CD, when it asks me to choose a disk for the root file system, the same 10 disks show up:

8/8.9.0
8/8.8.0
8/8.5.0
8/8.11.0
8/8.10.0
8/4.9.0
8/4.8.0
8/4.5.0
8/4.11.0
8/4.10.0

Where are the other five disks coming from?

[Darrel Louis]

Hi,

Do you've a hardcopy of the ioscan, which you can attach.
Where the five disks create with pvcreate -B command by exident?

Are the 5 disks internal or in a Autoraid?

Wait for your answer

[Sandor Horvath_2]

It seems to be You have 2 SCSI may be FWSCSI controller, and You See all disk this 2 controller.
If it internal disk You connected with Cable this 2 Controller. It works if the controllers SCSI ID doesn't same. If you autoraid it mean You use correct this 2 controller.

If any other case please write more ...

regards, Saa

There is no OS on the machine at present, I am trying to install it now. So I have no ioscan information.

Here's the hardware in the machine, taken from the invoice from when it was purchased:

1 - A3579A D380/2
4 - A3408A 128MB Mem
5 - A3643A 4GB FWD SCSI-2 Disk
1 - A3715A CD-ROM
1 - HSC F/W/D Adapter
2 - A2679A EISA SE SCSI-2 Adapter

it goes on, LAN cards, MUX, etc.

On a D3XX the HP-HSC I/O slot the HW-Path is 4/5
EISA I/O Slots : 4/7

Can you check on the back of the Machine for the I/O slots + hardware path.

Can you also check if SCSI termination is oke on the system.

[Sandor Horvath_2]

Hi !

The internal controller is the 8/4.x.0 and the 8/8.x.0 is in the external controller . I suppose check your cable, because You see the internal disks in the external controller.

Disconnect any SCSI cable from your system and try sea again !

Looking into the server itself, the hot swap bay has a cable running up to the EISA slots. The cable on that end has two connectors - and each connector is plugged into the edge of a SCSI card.

Is it possible that it should only be plugged into one? Are both SCSI cards reporting the drives because of this?

And, I suppose, if that's the trouble, why does the cable have two connectors in the first place?

[Patrick Wallek]

Fred,

I would suspect that the cable from the hot-swap bay being connected to both SCSI cards is exactly your problem. Both cards are seeing the disks and reporting them back.

Unplug the cable from one of the SCSI Cards and you should only see 5 disks when you do an SEA or attempt to do the installation.

[Fred Martin_1]

I think I have the answers now - I unplugged one of the two connectors on the EISA side of the cable, and was left with 5 drives, all on 8/4.x, so I will leave it that way.

[Angus Crome]

I do believe that you can use both cards to function with Alternate links to the drives. The only possible reason would be for card failover. Any other problem would show up for both controllers. However, I think a card failure would generate constant bus resets on the other one anyway. If this is what was intended originally, then the second controller can't have scsi ID #7 either.

Sounds to me like the box was not factory new, or the design teams were helping out with assembly (not likely).

[Fred Martin_1]

The box was a refurb, and we did ask the vendor add several SCSI cards to the system, which they installed before shipping. In fairness to them, I had removed one of the two SCSI cards mentioned above, then put it back. So it was most likely me that plugged both connectors in, one to each card - not the vendor.
