File contents

 

Description

 

 

 

Initted

 

The driver has loaded and successfully initialized the

 

 

IBA6110.

Present

 

The IBA6110 has been detected (but not initialized

 

 

unless Initted is also here).

IB_link_up

 

The IB link has been configured and is in the active

 

 

state; packets can be sent and received.

IB_configured

 

The IB link has been configured. It may or may not

 

 

be up and usable.

NOIBcable

 

Unable to detect link present. Can be caused by no

 

 

cable plugged into the QHT7140 or QLE7140, or

 

 

connected there but not to a switch, or the switch it

 

 

is connected to is down.

Fatal_Hardware_Error

 

Only appears if there is trouble.

 

 

 

In this same directory are other files containing information related to status. They are summarized in table C-4.

File name

Contents

 

 

lid

InfiniBand Local ID (LID). The address on the IB fabric, similar

 

conceptually to an IP address for TCP/IP. The "Local" refers to it being

 

unique only within a single IB fabric.

mlid

The Multicast Local ID (MLID), for IB multicast. Used for doing

 

InfiniPath ether broadcasts, since IB has no concept of broadcast.

guid

The Globally Unique ID (GUID) for the InfiniPath chip. Equivalent to

 

an Ethernet MAC address.

nguid

The number of GUIDs that are used. If nguids == 2, and two chips are

 

discovered, the first one will be assigned the requested GUID (from

 

eeprom, or ipath_sma), and the second chip gets that GUID+1.

serial

The serial number of the QHT7140 or QLE7140 board.

unit

Unique number for each card or chip in a system.

status

The numeric version of the status_str file, described in the

 

preceding table.
