Setting A Takeover Ip Address - Fujitsu M10 Installation Manual

7.5.3

Setting a takeover IP address

You can set a takeover IP address for a system that consists of multiple SPARC
M10-4S units and has multiple XSCFs.
The setting of the takeover IP address enables takeover of the IP address after
switching of the master and standby sides in cases of XSCF failover. By using the
takeover IP address, users can always connect to the master XSCF without any need
to pay attention to XSCF switching.
After setting the respective IP addresses for XSCF-LAN#0 and XSCF-LAN#1 as
described in
address for each pair of XSCF-LAN#0 and XSCF-LAN#1. (See (3) in
Figure
1.
Set the takeover IP address of XSCF-LAN#0 or XSCF-LAN#1.
The following example sets the takeover IP address 192.168.1.z and net mask
255.255.255.0 for XSCF-LAN#0, and the takeover IP address 192.168.2.c and net
mask 255.255.255.0 for XSCF-LAN#1.
XSCF> setnetwork lan#0 -m 255.255.255.0 192.168.1.z
XSCF> setnetwork lan#1 -m 255.255.255.0 192.168.2.c
7.5.4 Setting an SSCP IP address
For a system that consists of multiple SPARC M10-4S units and has multiple XSCFs, a
network is configured between the XSCFs to enable mutual monitoring of states and
exchange of system information. The interface protocol of this network is referred to
as the protocol for SP to SP communication (SSCP).
The IP addresses used in this SSCP network are set by default. However, if the
XSCF-LAN IP addresses and the default SSCP IP addresses have overlapping
network addresses, other values must be set for the SSCP IP addresses. For details on
SSCP IP addresses, see "3.7.5 Understanding the IP addresses that are set with
SSCP" in the Fujitsu M10/SPARC M10 Systems System Operation and Administration
Guide.
The IP addresses used with SSCP are classified and set in the following groups. These
groups are distinguished by their SSCP link network IDs. At least two IP addresses
need to be set for the same SSCP port.
Group with the master XSCF and the XSCF of each BB:
■
SSCP link network ID 0 (See (1) in
Group with the standby XSCF and the XSCF of each BB:
■
SSCP link network ID 1 (See (2) in
Group with the master XSCF and the XSCF of each XBBOX:
■
SSCP link network ID 2 (See (3) in
Group with the standby XSCF and the XSCF of each XBBOX:
