2 – InfiniPath Cluster Administration
Configuration and Startup

Q
Step 3 is applicable only to SLES 10; it is required because SLES 10 uses a newer
version of the
udev subsystem.
NOTE: The MAC address (media access control address) is a unique identifier
attached to most forms of networking equipment. Step 2 below determines
the MAC address to use, and will be referred to as $MAC in the
subsequent steps. $MAC must be replaced in each case with the string
printed in step 2.
The following steps must all be executed as the root user.
1. Be sure that the ipath_ether module is loaded:
# lsmod | grep -q ipath_ether || modprobe ipath_ether
2. Determine the MAC address that will be used:
# sed ’s/^\(..:..:..\):..:../\1/’ \
/sys/bus/pci/drivers/ib_ipath/00/guid
NOTE: Care should be taken when cutting and pasting commands such as
the above from PDF documents, as quotes are special characters
and may not be translated correctly.
The output should appear similar to this (6 hex digit pairs, separated by colons):
00:11:75:04:e0:11
The GUID can also be returned by running:
# ipath_control -i

Note that removing the middle two 00:00 octets from the GUID in the above
output will form the MAC address
If either step 1 or step 2 fails in some fashion, the problem must be found and
corrected before continuing. Verify that the RPMs are installed correctly, and
that infinipath has correctly been started. If problems continue, run
ipathbug-helper and report the results to your reseller or InfiniPath support
organization.
3. Skip to Step 4 if you are using SUSE 9.3 or SLES 9. This step is only done on
SLES 10 systems. Edit the file:
/etc/udev/rules.d/30-net_persistent_names.rules
If this file does not exist, skip to Step 4.
