6.1.2 When using SCSI reservation for shared disk

The following figure shows the system configuration procedure.

Figure 6‒3: System configuration procedure (when using SCSI reservation for shared disk)

The following explains the correspondence between the purpose for configuring the system and the steps in the system configuration procedure that must be performed.

• If you are installing HA Monitor and configuring a system for the first time

  Perform all the configuration steps shown in the figure.

• If you are adding hosts

  If you are adding hosts to an existing hot-standby configuration, perform all the configuration steps shown in the figure. You need one HA Monitor per host.

  Note that the step Configure VMware ESXi for use with HA Monitor is required only if VMware ESXi-based virtualization is used.

• If you are adding servers

  If you are adding servers to an existing hot-standby configuration, perform the configuration steps shown under Configuration steps when a server is added. The steps shown under Configuration steps when a host is added are not needed.

  The step Create server start, termination, and monitoring commands is required only for added servers that will run in the monitor mode. In this case, creation of a server start command is required, but creation of server termination and monitoring commands is optional.

  The steps Create program restart commands, Create and configure UAPs, and Create definition files (monitor-mode program) are required only for added servers that will run in the monitor mode and use the program management function.

For details about how to install HA Monitor and notes about installation, see Release Notes.

For details about how to add hosts and servers to an existing system, see 7.10.1 Adding hosts and 7.10.2 Adding servers.
