Point

It is possible to use a VM pool definition file to reduce the number of VM hosts on the switchover destination site. Refer to "Figure 2.4 Settings to Reduce the Number of VM Hosts on a Switchover Destination Site". For details on the VM pool definition file, refer to "4. Create a VM pool definition file [Virtual L-Server switchover (VM guest)]" in "3.6 Creating Files Used for Switchover".
Can be performed with physical L-Server switchover (physical OS).
Cannot be performed with physical/virtual L-Server switchover (VM host/VM guest).
Disks storing storage areas of VM hosts are not regarded as replication targets. Therefore, it is possible to locate the system areas of VM hosts on any disks. (Example: local boot)

Note

It is necessary to install the VMware vSphere Command-Line Interface (vCLI) on the servers that can communicate with VMware vCenter Server (such as admin servers).
Do not configure VM hosts on physical L-Servers.
Disks containing VM data

Use FC, iSCSI, or NAS connection disks as replication targets.
