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 

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:

# ibsrpdm -d /dev/infiniband/umad1 -c
# echo \
id_ext=21000001ff040bf6,ioc_guid=21000001ff040bf6,dgid=fe800000000
0000021000001ff040bf6,pkey=ffff,service_id=f60b04ff01000021 > 
/sys/class/infiniband_srp/srp-ipath1-1/add_target

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):

eth2: error fetching interface information: Device not found

To prevent the error message, remove the following files (assuming 
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.
