New Non-HP Disk

[Donald A. Sime]

I am trying to add some spare SCSI disks to an old K460. The adapter is differential but I found some ST118273WD drives and attached them. The IOSCAN found them but reports "unknown" as the hardware type and naturally no driver has claimed them.
I ran into this problem a few years ago and I think I put a new entry into /etc/disktab but that file now says it is unused and I checked on a system running newer disks and they aren't in the disktab.
I found an item that said that the hardware updates were being done via patches to the driver now. This box has recent patches on it, but they went on before the disk did so perhaps swinstall didn't think they were required.
There are other differential scsi disks active on this box so I expect that the required drivers are in the kernel and active.
I have the "geometry" so if someone tells me how to tell the driver about it I hope to be OK.

Hi Donald ,

It seems ST118273WD is 18GB disk and K460 supports that disk without making entry in disktab.

Hope some problem in connecting the disk , so that OS not able to detect it. You can try once.

good luck.

Raj.

are the other disks that are active on the box using the same type of controller? or are they fiber channel?

I would guess you are missing a driver in the kernel based on the unknown from ioscan.

[Donald A. Sime]

Well, if the disk is supported something else must be causing this. Any other ideas?

Can you see the new disk in PDC.
Using sea command.

[A. Clay Stephenson]

You need to make sure that the "disc3" driver is "In" in order to use disks with the 28696A controller.

[Raj D.]

Donald ,

Use this command to check that disc3 driver you have loaded properly,

$ lsdev -C disk
-----------------

Raj.

[Raj D.]

You should get like this :

#model
# model
9000/889/K460

# lsdev -C disk
Character Block Driver Class
177 28 disc3 disk
188 31 sdisk disk
#
--------------------------------

cheers ,

hi,

if the ioscan output is correct you have a clash of scsi id's.

2 disks are set to id6 and 2 disks are set to id9.

change the id's and reboot the system to pdc stop it from booting and do a search there.

you should see all 4 at different id's

Thanks all

The problem was that disk3 was not in.
I knew that it wasn't in but when I check another machine it wasn't there either, but that machine didn't have the same controller.

I put disk3 into the kernel and it came up happy as clams.

Donald ,

good to know that the problem solved .

Hope it would be a good idea now , to assign the points , to the responses .

Thx & Cheers ,
Raj.
