Known Issue
Workaround
When canceling out of a Host Channel Adapter firmware
update, the following message is shown:
HCA update failed. Return code: 1 at
/usr/bin/qlgc_firmware_tool line 264, STDIN line
2.
This message can be ignored; it indicates
that the Host Channel Adapter firmware
was not updated due to the user
canceling the operation.
For SLES10 SP2, the --32bit option of INSTALL will not
work. For individual Red Hat Package Manager (RPM)
installs, the SLES10 SP2 does not distinguish between 32-
bit and 64-bit RPMs. Installed RPMs that are 32-bit must be
manually uninstalled first and then the appropriate RPM for
each package (only 64 bit if available) must be installed.
QLogic recommends using ./INSTALL,
which automatically performs all
necessary uninstalls of old RPMs prior to
installing the new 64-bit RPMs.
Issues have been observed when using IPv6 with IPoIB on
Red Hat Enterprise Linux 4.
If using IPv6 with IPoIB, QLogic
recommends using Red Hat Enterprise
Linux 5.
When using opensm, the incorrect Node Description may
be reported for hosts after they are rebooted.
Restart opensm.
QLogic recommends using the QLogic
Fabric Manager to correctly handle
changes to host nodenames and host
reboots. If using opensm when seeing
this problem, opensm can be restarted.
When reinstalling QLogic OFED+, it may try to stop existing
instances of opensm. If opensm is not presently running, it
will report:
Stopping IB Subnet Manager [FAILED].
QLogic recommends using the QLogic
Fabric Manager.
If the QLogic Fabric Manager is installed
instead of opensm, this error will not
occur.
When using vFabric, the OFED saquery command may use
the wrong P-Key and timeout waiting for responses.
QLogic recommends using the
iba_saquery tool, which is included with
QLogicIB-Basic or QLogicIB-IFS.
iba_saquery will work properly when
vFabric is configured.
If LD_LIBRARY_PATH is exported inconsistently with the
version of openmpi being used, applications may build or
run incorrectly. This issue can impact FastFabric tools that
use MPI, rebuilding of mpi apps, or rebuilding openmpi
itself using the do_build or do_openmpi_build tools.
When using openmpi, make sure PATH
and LD_LIBRARY_PATH are not exported
specifying a different path than the
openmpi path that is being used. The
mpi-selector can configure a
LD_LIBRARY_PATH for subsequent logins.
Openmpi does not require the
LD_LIBRARY_PATH to be set.
When using opensm, after bouncing ports on a node, the
port may not return to an active state for a period of time.
As a result, commands that issue an SA query such as
OFED's saquery command, or various FastFabric tools such
as iba_report and iba_saquery, may hang waiting for the
port to become active and the SA to respond.
Restart opensm.
QLogic recommends using the QLogic
Fabric Manager, which has much greater
resiliency and quicker handling of port
state changes.
Test ib_rdma_bw fails if it detects conflicting CPU
frequencies.
Use the -F option (do not fail even if
cpufreq_ondemand module is loaded)
when running this test. This option is not
documented, but is required for this
environment.
When using vFabric to change an IPoIB application from
Networking to Non-Networking, the IPoIB interface may
remain in a running state.
After changing the application, restart the
network services or bring the interface
down/up to force IPoIB to re-query the
SM and correct the situation.
