Hardware Paths physical locations

[Jacky Wing]

How can i know which path is for which physical location.
I have an Rx6600 with 6 NICs, I don't want to go there and try reading the small information on the nic card to know the port & ...
HP used to have something like "Service Guide" but it is not listing the locations.
Is there any other way?

Hi,

Suppose you want to know the hardware path for your lan card then fire #ioscan -fnC lan. for disk #ioscan -fnC disk ....

No, I want to know the physical location of the hardware path 0/7/0/0/0 for example. Where is it located?
for example the disks, where is the disk at path 0/3/0.1.0 (for example) is located?
I know i can turn the light on for this model, but I need to have a map that shows where each hardware path is physically located.
It exists for the RP7000 series in their service guide, but I couldn't find anything useful for RX6600 & RX2660.

You can try ioscan -funClan, once you get the h/w path you can get slot from
olrad -q

hello

you should know the component corresponding to the below names "e.g SBA and LBA"
It depends on your system whether it is processor based or cell based.

For example:
Processor-based hw path format: SBA/LBA/device/function.target.LUN
Processor-based hw path example: 0/0/2/0.6.0
Processor-based hw path explanation: SBA=0, LBA=0, dev=2, function=0, target=6, LUN=0

The HP-UX kernel identifies cards and devices via HP-UX hardware paths,
which describe a deviceâ s logical location in the kernelâ s I/O tree structure in memory.

Cell-based hw path format: Cell/SBA/LBA/device/function.target.LUN
Cell-based hw path example : 1/0/0/2/0.6.0
Cell-based hw path explanation: Cell=1,SBA=0, LBA=0, dev=2, function=0, target=6, LUN=0

Try

# olrad -q

this delivers information about most slots (hot-swap slots).

Then compare with "lanscan".


Example:

# olrad -q

Hi,

Hardware paths are present only for the purpose of configuration and management. To find the physical location, we have the concept of slot address which follows the format Cabinet-Bay-Chassis-Slot which will give the exact physical location of the slot. And as the folks mentioned above olrad -q should do it although this command is not supported on all servers.

How should I know the cell/SBA/LBA ...
it should be given by HP for each system. You cannot just guess it. for each new system there should be a hardware layout.
SBA/LBA connected to this port ---> hardware path is ...

If you ever opened the service guide for RP7 or RP8 series, you will directly see that they have a picture pointing the location of the disks and the hardware path associated. I can't find such information for RX6600 & RX2660. Can you know how to find it.

Olrad will show me the hardware path for the lan only, without the disks.

Disks are totally different here, because it is SAS. Pathes can differ.

Check if you use the default SAS controller or an optional P400 and use sasmgr or sautil/config to find the details.


Example:

# sasmgr get _info -D /dev/sasd0 -q raid
