Known Issue
Workaround
When installing the QLogic-Basic or QLogic-IFS SW on
SLES10SP3, there may be conflicts with software that is
already installed on the system. The following message
may appear:
error: %preun(ofed-1.4.1-0.14.9.x86_64) scriptlet
failed, exit status 1
Manually uninstall the old version OFED
before you install the newer software.
1. As root, run the following command:
rpm -e --noscripts ofed
2. Re-run the normal installation.
When installing the QLogic-Basic or QLogic-IFS SW on
SLES11SP1, there may be conflicts with software that is
already installed on the system. The following message
may appear:
error: %preun(ofed-1.4.2-0.9.6.x86_64) scriptlet
failed, exit status 1
error: %preun(opensm-3.2.6_20090317-
0.1.42.x86_64)scriptlet failed, exit status 1
Unable to uninstall previous OFED RPMs
Manually uninstall the old version OFED
before you install the newer software.
1. As root, run the following command:
rpm -e --noscripts ofed
2. Re-run the normal installation.
When uninstalling MVAPICH2 (for any verbs or PSM), some
files under the /usr/mpi/*/mvapich2*/ directory tree that
are created at runtime by MVAPICH2 may not be removed.
One example is mpdlib.pyc.
After uninstalling, remove any undesired
files left in the /usr/mpi/ directory.
When a long netperf test is run between hosts using
QLE7240 and QLE7280 DDR Host Channel Adapters, the PM
is unable to get or set port counters for these Host Channel
Adapters.
For example, the netperf command, netperf -l 360 -H
<ib0 IP address for netserver host> (-l 360 means
the test will run for 360 seconds; the default is 10
seconds), causes the QLogic IFS tool iba_top to produce
warning messages about being unable to get or set port
counters.
Do not run long netperf test between
hosts using QLE7240 or QLE7280 DDR
Host Channel Adapters.
When running the OFED performance benchmark qperf to
test the bandwidth of Unreliable Datagram (UD) traffic, the
command hangs or times out intermittently when using an
InfiniBand MTU of 4096 bytes and the '-t 10' (or larger
number of seconds). For example:
qperf hostname -m 4096 -t 10 ud_bw
Run the command without the -t option.
For example:
qperf hostname -m 4096 ud_bw
When running bidirectional traffic on a QLogic Host Channel
Adapter in unreliable connection (UC) mode on certain
server types, the Ethernet connection drops or the adapter
can exhibit panics.
For an Ethernet connection drop, perform
a service network restart.
For panic state, power cycle the server to
recover.
When performing an IFS installation on SLES 11 SP1, a
message similar to the following may appear:
WARNING: -e needs -E or -F
This message can be ignored.
On SLES 11 or SLES 11 SP1 environments, when running
qperf rc_bi_bw or rc_rdma_read_lat tests, the system
can have a kernel panic causing it to drop a vmcore file and
reboot. This kernel panic also occurs with OFED 1.5.2.
Do not run these qperf tests on SLES 11
environments.
