Configuration Issues
ibsrpdm Command Hangs when Two Adapters are Installed
but only Unit 1 is Connected to the Switch
If multiple adapters (unit 0 and unit 1) are installed, and only unit 1 is connected to
the switch, the ibsrpdm command (to set up an SRP target) can hang. If unit 0 is
the switch, the ibsrpdm command (to set up an SRP target) 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 the ibsrpdm
command. Then, using the output from the ibsrpdm command, echo the new target
information into /sys/class/infiniband_srp/srp-ipath1-1/add_target.
For example:
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Outdated ipath_ether Configuration Setup Generates Error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).
When ifconfig or ifup is run, the error looks similar to the following (assuming
ipath_ether was used for eth2):
modprobe.conf (for example, alias eth2 ipath_ether).
When ifconfig or ifup is run, the error looks similar to the following (assuming
ipath_ether was used for eth2):
eth2: error fetching interface information: Device not found
To prevent the error message, remove the following files (assuming
ipath_ether was used for eth2):
ipath_ether was used for eth2):
/etc/sysconfig/network-scripts/ifcfg-eth2 (for RHEL)
/etc/sysconfig/network/ifcfg-eth-eth2 (for SLES)

QLogic recommends using the IP over InfiniBand protocol (IPoIB-CM), included in
the standard OpenFabrics software releases, as a replacement for
ipath_ether.
