(3) Configuration consisting of two chassis and four hosts (Basic mode)

This subsection explains an example of reset path settings in a system that runs under the following conditions:

The system contains two pairs of 1-to-1 switchover configurations that do not monitor each other.
Two pairs of hot-standby configurations share the reset path.
Two pairs of hot-standby configurations share the SVP.

Important: In the hot-standby configuration explained here, the specification of host address (address operand in the HA Monitor environment settings) requires special care. For details, see (2) Notes about sharing a reset path among hot-standby configurations.

The following shows an example of settings specified with the monsetup command for the configuration shown in the following figure (performing the hot standby operation between hosts 1 and 3 and between hosts 2 and 4) that satisfies all the above conditions. Some models of BladeSymphony allow you to set a different port number for each hot-standby switchover configuration by using the HA Monitor linkage settings of SVPs. The following shows setting examples in the cases where different port numbers are set and the same port number is set for hot-standby switchover configurations.

(a) Case where different port numbers are set for two switchover configurations

(b) Case where the same port number is set for two switchover configurations

The following shows an example of values to be specified in the monsetup command under the conditions shown earlier. In this example, hosts 1 and 3 make up one hot-standby switchover pair, and hosts 2 and 4 make up another hot-standby switchover pair.
