About the Management LIF Setting Port
When collecting logs during maintenance work, confirm that e0M is the Management LIF port and
collect it from e0M. However, if a port other than e0M is used, cooperation from the customer may
be required.
About the Segment of SP/BMC (e0M) and Data LIF
If the segment of SP/BMC (e0M) and Data LIF are the same, the data that should flow in Data LIF
flows in SP/BMC (e0M) instead and may become a performance bottleneck. If the operation envi-
ronment can be operated in a segment that differs from the IP address of SP/BMC (e0M), set Data
LIF with a segment IP address that is different from SP/BMC (e0M).
In addition, if the data network segment has a high load in the ETERNUS AX/AC/HX and the data
network and e0M are in the same segment, the data that should flow in the data network instead
flows through the e0M and causes SP/BMC to malfunction, which in turn may cause high-speed
rotation of fans, detection of sensor malfunctions, and finally, a shutdown (takeover). If a shutdown
occurs simultaneously on both nodes, the system may fail. To avoid this, separate the data network
segment from the SP/BMC (e0M) segment.
About the IP Address Setting of SP/BMC (e0M)
For the NIC of SP/BMC (e0M), do not set the network address within the range of "10.1.1.0/24". If it
was set within that range, SP/BMC may continually reboot, the fans may rotate at high-speed, and
the volume may become loud.
About the Ports That Are Set as Cluster LIFs
In a cluster network, the controllers are connected to each other using the cluster LIFs, and the
ports used for the cluster LIFs are defined for each model. If a port used for the cluster LIFs is
changed to a port that is not defined in advance, the redundancy or the performance may degrade.
Do not change the ports used for the cluster LIFs to ports that are not defined in advance.
