Table C-3. status_str File
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.
Table C-4. Other Files Related to Status
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.
