how to find out how many PCI connected to the chassis?

[Jeff.Z]

for example, we have a chassis, its hardware location is like this, cab0,bay0,chassis1 (0/0/1). so, how to tell how many PCI devices connected to this chassis? the only thing i can find thru rad is the chassis itself. Thanks.


=>rad -q|grep "0/0/1"
0-1-3-1 0/0/1/1 8 133 133 On Yes No Yes PCI-X PCI-X
0-1-3-6 0/0/14/1 112 266 266 On Yes No Yes PCI-X PCI-X
0-1-3-7 0/0/13/1 104 133 0 Off No N/A N/A PCI-X PCI
0-1-3-8 0/0/12/1 96 133 0 Off No N/A N/A PCI-X PCI
0-1-3-9 0/0/10/1 80 133 0 Off No N/A N/A PCI-X PCI

The sixth column is the power state. If the power is on, this is a good indication for an installed card.

You can also check the olrad -q output against an ioscan.
If there is nothing below a LBA, there is no card installed.

[Jeff.Z]

Torsten,

Thanks for your reply. from what i know, a chassis can connect to 6-PCI or 12-PCI card cage on a Superdome. In my case, the chassis 0/0/1 is powered on, and 2 SCSI interfaces connected to this chassis. I need to find out, whether 12 or 6 interfaces could connect to this chassis though.

[Sandman!]

That can be obtained from the output of ioscan. Simply run ioscan(1M) with the hardware path as the argument. That will give a heirarchial form of device tree report. You could also post the output here:

# ioscan -H 0/0/1

[Jeff.Z]

Sandman,

It's the same thing i posted on last thread. Only 2 SCSI adapters connected to the chassis. My question is how many interfaces can be connect to this chassis? e.g., if i want to connect 10 more PCI, could it be done? thanks.

[Torsten.]

We are talking about a superdome?

There was never a 6 slot chassis.

From the ioscan you sent: there is only 1 card (dual port) installed.

[Sandman!]

From the ioscan(1M) output it looks like there is only one PCI turbo card installed on your system.

[Sandman!]

Didn't read your post thoroughly. What kind of server (make and model) is this? That information would help in resolving this issue.

[Torsten.]

You always give a little less information.

I would suggest to run

olrad -q
ioscan -fndlb

and check down the lba pathes with
ioscan -fnH ...

If there is nothing below the lba, there is no card.

From your first "olrad" command I would assume there is another card in
0-1-3-6 0/0/14/1

[Jeff.Z]

Torsten,

You're right, only 1 dual port card installed. So, 12 interfaces can be connect to this chassis on the Superdome, correct?

Thanks,
Jeff

[Jeff.Z]

Guys,

sorry for the less of information. The server is a 9000/800/SD32B. I just want to know how many PCI cards can be connected to the chassis 0/0/1 and how many are connected for now. From what Torsten said, this chassis can support 12 cards and has 1 dual ports SCSI connected currently.


Thanks for all your help.

Jeff

[Torsten.]

Yes, but depending on the model and config 1 slot may require a core I/O card.

[Torsten.]

I don't know how many cards are there, because you always post small parts from the output.

There is definitely a card in slot 1.

I assume there is at least another card in slot 6.

[Torsten.]

"...connected to the chassis 0/0/1..."

Be careful!
Don't mix up!

From your small output of olrad:

0-1-3-1 0/0/1/1 8 133 133 On Yes No Yes PCI-X PCI-X


"0-1-3-1"
This is the slot location in the box.

"0/0/1"
This is the hardware path from cell 0 to slot 1 in the connected IO chassis (only 1 slot !).

"0/0/14"
Is another slot in the same chassis (slot 6).

[Jeff.Z]

Torsten,

Here comes the complete "rad", "parstatus -I" and the "ioscan -fn" output. What is the hardware address for this chassis??? cab0,bay0,chassis1 Active - cab0,cell2 0
Thanks a bunch.

That's better now!

Have a look at the IO chassis connected to cell 0:

0-1-3-0 0/0/0 0 133 0 Off No N/A N/A PCI-X PCI
0-1-3-1 0/0/1/1 8 133 133 On Yes No Yes PCI-X PCI-X

0-1-3-4 0/0/5/1 40 133 0 Off No N/A N/A PCI-X PCI
0-1-3-5 0/0/6/1 48 266 266 On Yes No Yes PCI-X PCI-X

0-1-3-10 0/0/9/1 72 133 133 On Yes No Yes PCI-X PCI-X
0-1-3-11 0/0/8/1 64 133 0 Off No N/A N/A PCI-X PCI

These slots are powered "ON":

0-1-3-1 0/0/1/1
0-1-3-2 0/0/2/1
0-1-3-5 0/0/6/1
0-1-3-6 0/0/14/1
0-1-3-10 0/0/9/1

Now look at a slot powered OFF:

0-1-3-3 0/0/4/1

ioscan gives:

ba 4 0/0/4 lba CLAIMED BUS_NEXUS Local PCI-X Bus Adapter (785)

That's it - no more 0/0/4 ... pathes - slot is empty!

Now back to the powered slots:

slot 1:
0/0/1
Dual SCSI card (SCSI Ultra320 A6961)

slot 2:
0/0/2
4 port LAN

slot 5:
0/0/6
4GB FC card (AB379)

slot 6:
0/0/14
4GB FC card (AB379)

slot 10:
0/0/9
dual port LAN (A7012)



How many slots are free here???

Now guess!

[Jeff.Z]

totally understand now. in your example, 5 slots are in use, 7 are free. :D

[Torsten.]

Posted before read?

The notation is

Location 0-1-3-1
Hardware path 0/0/1/1

Location is
Cabinet#-Bay#-Chassis#-Slot#

Cabinet = 0
Bay = 1 (back)
Chassis = 3 (right)
slot = 1

for hardware path 0/0/1 in this case.

Now go to the cabinet, open the rear door and take a look at the right Chassis.
You will find your dual port SCSI card there in slot 1.


Clear now?

[Jeff.Z]

Crystal clear, thank you.

[Jeff.Z]

All clear, thanks.

As you learned now, understanding this is important and will help you.


But now you can go also the easy way:

Log on to the system management homepage, if installed:

http://your_server:2301

Once logged on and re-directed, go to

From here you can really *see* all this information.
