This same directory contains other files with information related to status. These
files are summarized in Table F- 6.
Table F-5. status_str File Contents
File Contents Description
Initted The driver has loaded and successfully initialized
the IBA6110 or IBA7220 ASIC.
Present The IBA6110 or IBA7220 ASIC has been detected
(but not initialized unless Initted is also present).
IB_link_up The InfiniBand link has been configured and is in
the active state; packets can be sent and received.
IB_configured The InfiniBand link has been configured. It may or
may not be up and usable.
NOIBcable Unable to detect link present. This problem can be
caused by one of the following problems with the
QHT7140, QLE7140, QLE7240, or QLE7280
adapters:
No cable is plugged into the adapter.
The adapter is connected to something other
than another InfiniBand device, or the connector
is not fully seated.
The switch to which the adapter is connected is
down.
Fatal_Hardware_Error Check the system log (default is /var/log/mes-
sages) for more information, then call Technical
Support.

File Name Contents
lid InfiniBand LID. The address on the InfiniBand fabric, similar concep-
tually to an IP address for TCP/IP. Local refers to it being unique
only within a single InfiniBand fabric.
mlid The Multicast Local ID (MLID), for InfiniBand multicast. Used for
InfiniPath ether broadcasts, since InfiniBand has no concept of
broadcast.
guid The GUID for the InfiniPath chip, it is equivalent to a MAC address.
