Q-Logic IB0056101-00 G.02 Configuration Issues, Check your distribution for the exact RPM name

Installation Troubleshooting Configuration Issues

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This is not an issue when upgrading to a newer version of the InfiniPath software.

Configuration Issues

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 -doption 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Outdated ipath_ether Configuration Setup Generates Error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).
