HP DL380 G5 SAS Expander

So, we have installed a SAS expander card, cables (same length) and caddy with disks.  
I have power cable from backplane of caddy to m'board.
I have 1x sas lead going from port 1 on backplane to port 8c on sas card & I have the other lead going from port 2 on the backplane to port 9c on sas card.

Going into the p400 bios is can only see 8x disks.

Why?

There should be 4 SAS cables from the expander to the two backplanes and two SAS cables from the motherboard to the expander, you've only mentioned 2 cables from expander to backplane.

Took me a while to get my head around it, it's a PCIe x8 card but if you run insight diagnostics and list what's in the PCIe slot it says it's empty. The card just contains a SAS expander chip which gets its input from the motherboard via SAS cables and sends its output to the disks via SAS cables. It doesn't show up on the PCIe bus because it isn't connected to it and only plugs into the socket so it can get power. It needs the large x8 connector for the extra power pins because without all that power you couldn't fry an egg on the heatsink.

I did cover that in your other question so feel free to delete this one if it's just wired up wrong.BTW, it is a G6 or G7, G5 doesn't take a second backplane.

I see the pairs of cables must be in similar lengths but which cables go from mboard to controller and which go from controller to backplanes?

I have 493228-006 x4  
and 493228-005 x4 - about 4" shorter than above....

as getting error.

drive array controller failure.

You can use either -006 or -005 to go from the expander to the backplanes as long as all 4 match. Two of the remaining cables can be used to connect the expander to the motherboard (that's where the 8" cables come in if you bought them, it's tidier and airflow isn't blocked so much).

Are ports 8c and 9c connected to the motherboard?

There's an illustration in the following document (though not a very good one since they have only connected one motherboard port which is supported but only has half the bandwidth.

Thanks, i have seen that one before...

Yes i have port 8c going to port A on mboard and port 9c going to port B on mboard.
then had ports 2c&3c going to ports 1&2 respectively on caddy 1.
then had ports 4c&5c going to ports 1&2 respectively on caddy 2 (new case)

not sure on which cables i had connected (as just disconnected them all) but 100% sure the same lengths were used.

possibly firmware?

actually think i had longer leads going from card to backplanes....
will try other way now....

Author

Commented:
no, not long enough
Top Expert 2014
Commented:
Yes, possibly firmware, or possibly corrupt cache module which you can clear by unplugging and disconnecting the battery for a minute or so.

Author

Commented:
is that the module next to the on board sas ports or near the front of server?
Top Expert 2014
Commented:
Cache module is next to the SAS ports, battery or supercapacitor is on airflow bezel if there is one.

Commented:
ok, ran the smart start cd and ran automated process to install firmware etc, however still getting error on raid controller.

i am sure this is cabled right!!!!1
Top Expert 2014

Commented:
That message sometimes means the controller has failed, I know it's a bind but you'll really have to prove that out by taking the SAS expander out again.

Commented:
SO, took out the module for a few minutes.  Reseated.  Removed sas expander card.  Re-fitted original setup - powered on acknowledged error message, F8 into BIOS exited and restarted and thus worked fine.

Reseated the card (but in different picx slot) cabled up as before, same error!

Can you confirm which leads go where?

To confirm i get:

Slot 0
1783 – slot 0
Command failure: (cmd=11h, err=20h, dlu=oAB:2ch)
Drive array controller failure!

We have tried it in both pcix slots
We have tried the sas card using different length cables
We have updated the firmware using the hp firmware maintenance cd v10

The onboard controller works fine without sas which is why I think there could be issues with these cards and g7’s…

I've put them in G7s several times but it sounds like you just got a faulty one. They are the correct part for the server since they're in the quickspecs. http://h18004.www1.hp.com/products/quickspecs/13595_na/13595_na.HTML

OK, i'll try another new one.
btw, the sas card comes with 2x pairs of different lengths.  I would have expect 4x same length...
Top Expert 2014

Commented:
One pair's for the ML/DL370 I think, so they put both lengths in so you can match the length of the cables the server came with. A bit like the DVD rom upgrade kit comes with half a dozen different cables for different servers.

ok, new sas card also doesnt work!!!!!!!!!!!!!!!!!
