Re: Strange HDD order

Greetings programs!

I have a computer here with 10 HDDs. Four of them are connected to the
southbridge of the mainboard. The other 6 are connected to two Promise
SATAII 300 TX4. Four of the drives are connected to the first controller
(making it 'full') the other two connected to the second.

To make the device names predictable I was very careful how I connected
them. The four drives connected to the southbridge are in the right order
(this also means they have the device names ad0 to ad3). The drives
connected to the other controllers are a different story.

The two controllers cooperate well and identify themselves as one
controller only. So I get only one message showing all the drives. The
drives are in this order in the BIOS message:

D 0 WDC WD3200SD-01KNB0 08.05J08 (ad4)
D 1 WDC WD3200SD-01KNB0 08.05J08 (ad6)
D 2 SAMSUNG HD501LJ CR100-11 (ad8)
D 3 SAMSUNG HD501LJ CR100-11 (ad10)
D 4 Seagate ST3500320AS SD04 (ad12)
D 5 Seagate ST3500320AS SD04 (ad14)

The device in brackets is the one I'd expect to get. Instead, I get this:

ad4: 476940MB <SAMSUNG HD501LJ CR100-11> at ata2-master SATA300
ad6: 305245MB <WDC WD3200SD-01KNB0 08.05J08> at ata3-master SATA150
ad8: 476940MB <SAMSUNG HD501LJ CR100-11> at ata4-master SATA300
ad10: 305245MB <WDC WD3200SD-01KNB0 08.05J08> at ata5-master SATA150
ad14: 476940MB <Seagate ST3500320AS SD04> at ata7-master SATA150
ad18: 476940MB <Seagate ST3500320AS SD04> at ata9-master SATA150

Where did I go wrong?

How disks ars numbered do depend on which ports on which controller they
are attached to. You want to use the lowest-numbered ports on the Promise
controllers. Which ports that is when both controllers identify as a single
controller is another question. From what you show it looks like all the
odd-numbered ports are on one controller and all the even-numbered ports are
on the other.

Try experimenting by changing which disk is connected to which port and see
if you can get the behaviour you want.
