Note
Using a VM pool definition file can reduce the number of VM hosts in the backup site. Refer to "Figure 2.4 Settings to Reduce Number of VM Hosts Using a Backup Site". For details on configuration, refer to "4. Create a VM pool definition file [Virtual L-Server switchover (VM guest)]" in "3.6 Creating Files Used for Switchover".
It is necessary to install the VMware vSphere Command-Line Interface (vCLI) on the servers which can communicate with VMware vCenter Server (such as admin servers).
Can be performed with physical L-Server switchover (physical OS)
Cannot be performed with physical/virtual L-Server switchover (VM host/VM guest)
Do not configure VM hosts on physical L-Servers.
Disks containing VM data
Use FC, iSCSI or NAS connection disks as replication targets.
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)
