In older distributions, such as RHEL4, the 32-bit glibc is contained in the libgcc
RPM. The RPM name will be similar to this:
libgcc-<version>.EL4.i386.rpm
In newer distributions, glibc is an RPM name. The 32-bit glibc is named
similarly to:
glibc-<version>.i686.rpm OR
glibc-<version>.i386.rpm
Check your distribution for the exact RPM name.

Lockable Memory Error on Initial Installation of InfiniPath

During the first installation of InfiniPath software, /etc/initscript is created or
modified to increase the amount of lockable memory (up to 128 MB) for normal
users. This change will not take effect until the system is rebooted, and jobs may
fail with error messages about locking memory or failing mmap. This error is
described in the QLogic MPI Troubleshooting section “Lock Enough Memory on
Nodes When Using a Batch Queuing System” in the QLogic HCA and QLogic
OFED Software User Guide.
This is not an issue when upgrading to a newer version of the InfiniPath software.

ibsrpdm Command Hangs When Two HCAs are Installed but

Only Unit 1 is Connected to the Switch

If multiple HCAs (unit 0 and unit 1) are installed, and only unit 1 is connected to
the switch, the ibsrpdm (to set up an SRP target) command can hang. If unit 0 is
connected, and unit 1 is disconnected, the problem does not occur.
When only unit 1 is connected to the switch, use the -d option with ibsrpdm,
then, using the output from the ibsrpdm command, echo the new target info into
/sys/class/infiniband_srp/srp-ipath1-1/add_target.
For example:
# ibsrpdm -d /dev/infiniband/umad1 -c
# echo \

Outdated ipath_ether Configuration Setup Generates Error

Ethernet emulation (ipath_ether) has been removed in this release, and, as a
result, an error may be seen if the user still has an alias set previously by
modprobe.conf (for example, alias eth2 ipath_ether).
