Fault-Tolerant LAN Configuration
HP recommends that you use a fault-tolerant LAN configuration. A fault-tolerant configuration
includes these connections to two maintenance switches as shown in example Figure 6-2 (page 84):
• A system console to each maintenance switch
• One connection from one Onboard Administrator (OA) in the c7000 enclosure to one
maintenance switch, and another connection from the other Onboard Administrator to the
second maintenance switch
• One connection from one Interconnect Ethernet switch in the c7000 enclosure to one
maintenance switch, and another connection from the other Interconnect Ethernet switch
to the second maintenance switch
• For every CLIM pair, connect the iLO and eth0 ports of the primary CLIM to one maintenance
switch, and the iLO and eth0 ports of the backup CLIM to the second maintenance switch
— For IP CLIMs, the primary and backup CLIMs are defined, based on the CLIM-to-CLIM
failover configuration
— For Storage CLIMs, the primary and backup CLIMs are defined, based on the disk path
configuration
• A Storage CLIM to one maintenance switch and another Storage CLIM to the other
maintenance switch
• One of the two IOAM enclosure ServerNet switch boards to each maintenance switch
(optional)
• If CLIMs are used to configure the maintenance LAN, connect the CLIM that configures
$ZTCP0 to one maintenance switch, and connect the other CLIM that configures $ZTCP1
to the second maintenance switch
• If G4SAs are used to configure the maintenance LAN, connect the CLIM that configures
$ZTCP0 to one maintenance switch, and connect the other CLIM that configures $ZTCP1
to the second maintenance switch
