1–Overview of the Release Product Limitations could become inconsistent and cause unreliable operation, in which case subsequent runs of ./INSTALL or iba_config may make incorrect conclusions about the configuration of the system and consequently make incorrect recommendations. If the system becomes inconsistently configured, QLogic recommends running the ./INSTALL TUI and selecting ReInstall on all components. Once the re-installation has started, carefully review all prompts and choices.
1–Overview of the Release Other Information Other Information The following is a list of “need to know” information for this release: When using Mellanox Host Channel Adapters, any changes to Virtual Fabrics (vFabrics) in the Fabric Manager, may require a reboot of the hosts with Mellanox Host Channel Adapters. This limitation relates to the Mellanox Host Channel Adapters not properly responding to changes to the Fabric Manager service level (SL).
1–Overview of the Release Other Information Older QLogic InfiniPath 2.2.1 and prior releases will not be recognized in the installation menus and will be treated as if no InfiniBand software is installed. When upgrading from an older QLogic OFED+ release to a new QLogic OFED+, the older QLogic OFED+ release will be uninstalled first. When installing the OFED Debug Info component, make sure that ~/.rpmmacros does not have any lines changing the %debug_package macro.
1–Overview of the Release Other Information mpirun-debug option fails to open xterm windows. A race condition may occur when there are multiple processes trying to lock the $HOME/.Xauthority file concurrently. An error similar to this may occur: /usr/X11R6/bin/xauth: error in locking authority file /home//.Xauthority Disable X11 forwarding by setting the environment variable $MPI_SHELL_X='ssh -x'. Then set the DISPLAY environment variable with the mpirun -display option.
1–Overview of the Release Other Information When users increase the number of processes beyond the number of open files allowed by ulimit, mpirun prints an error message. The ulimit for the number of open files is typically 1024 on both Red Hat and SLES. The message will look similar to the following: MPIRUN.up001: Warning: ulimit for the number of open files is only 1024, but this mpirun request requires at least number of files open files (sockets).
