HBA 64-bit or 32-bit

[Anand Sreenivasan]

How can I say whether the HBA I have on my N-CLASS is a 64-bit or a 32-bit card. Thanks for any help.

Get the model:
ioscan -fnC fc (or hba)

Then search http://partsurfer.hp.com

The slot specs for the server are at http://docs.hp.com

ioscan -fnC fc gives the following as the response,
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 0 0/4/0/0 td CLAIMED INTERFACE HP Tachyon TL/TS Fibre Channel Mass Storage Adapter
/dev/td0


I don't find the model number...

I _believe_ the Tachyon TL (aka, IIRC Tachlight?) was > 32 bit addressing capable. I suspect that the place to find the definitive answer would be somewhere on Agilent's website since Tachyon went with Agilent at the split.

Given that HP-UX I/O services "deals with it" why in particular do you want to know?

HBA ise an A6795A (Tachlight)
Part description:
PCI 4X (64-bit, 66 MHz) Single-Channel 2Gb Fibre Channel Adapter with LC connector type, auto negotiates 2GB or 1GB transfer mode.

hi,

it could also be an A5158A 1gb Fc mass storage adapter

Check with fcmsutil

#fcmsutil /dev/td0

This will list all info/fw version on card and part number
