HP9000 d270 ultra 2 / 3 disks

I while ago I was able to lay my hands on a HP9000 d270, just for playing around at home.

The machine has 2 original 4,3 Gb disks. I replaced the disks with 2 18 Gb Compaq ultra 3 disks but ioscan does not recognize the disks.

Is the hardware compliant? or do I need specific firmware for these disks?

It depend from SCSI type.
If your Controller is WD it can not work with LVD.
If not :) probably yes :)

New disks are LVD.

use ioscan -nf
Look for controller and you will see :)

The D270 can only use High-voltage differential SCSI disks (HVD FWD). The ultra3 you are trying to put in are LVD scsi. The 2 different types will NOT work together at all.

Hello Peter,
How did you replace the disks?
If you have FWD disk they are in a Hot Swap black box. Have you changed the internal mechanism of this boxes?. The Compaq hotswap chassis doesn`t fit in the hp9000 D270.

Or the disks were into the chassis fixed with screws and connected to an SCSI-2 bus (50 pin male connector)? In this case you don't have an FWD HV bus and maybe if you force your disk to SCSI-SE they can work.

Regards.

Peter,

The D270 has internal Single-Ended Drives (up to 2, IIRC) and they are installed similar to a K-class or a PC, with 4 screws in the sides of the drives to bolt them into a metal cage. the D370 has Fast-Wide Drives in a black case with a blue handle on the bottom of the drive for hot-swapping.

Which config is yours?

I thought the D270 had the option to go to the FWD disks. Need to do an ioscan to see exactly what you have, or double check the original drives. FWD and Ultra 2/3 are not electrically compatible. Note FWD is sometimes calle HVD or High Voltage Differential.

The D270 definitely can have the FWD Hot Swap cage put in. The D270 we have is configured as such.

I believe that the upgrade from the D2xx to D3xx *is* the FWD hot-swap cage. So technically, your D2xx was upgraded to a D3xx. According to the configuration guide, the D2xx series have SE SCSI internal drives.

Peter, how are you running ioscan if you can't use the internal drives?

Nope, it is definitely still a D270, but with the FWD hot-swap drive cage. One of the limits of the D2xx, with the FWD drive cage is that you can only put 2 drives in. When upgraded to a D3xx you can put up to 5 drives in the FWD hot-swap cage.

All the D2xx we have, or have had, are configured with the FWD hot-swap cage. And the all definitely still show up with the D2xx model number.

The D-class could have either SE-SCSI-2 or FW-SCSI-2 drives. I looked it up. The part number to upgrade from SE to FWD was A3341A and it used an HSC slot. This upgrade part number had to be ordered along with any FWD disk drives.
