System configuration
Note
Set the host OS as an NTP server and the guest OS as an NTP client, and then perform time synchronization.
If you want to use the system as a test environment, you can configure it so that the redundant administrative LAN is created on the guest OS by GLS. For information on how to create a redundant administrative LAN, see "PRIMEQUEST Virtual Machine Function User's Manual".
Assign more than two virtual CPUs to each guest OS which comprises the cluster system. For information on how to assign virtual CPUs to guest OSes, see "PRIMEQUEST Virtual Machine Function User's Manual".

Note
If you want to mirror the system disk by using GDS, see the section about redundancy in "PRIMEQUEST Virtual Machine Function User's Manual".
Shared disk array settings
Device name: | Number of LUN | Number of RAID groups | RAID level | Size |
3 | 3 | 5 | 248.2GB |
Note
The local class disks or shared class disks used by GDS on the guest OS should be created as virtual SCSI devices if they are used in the virtual machine environment.
Note that you cannot change the virtual SCSI device configurations after creating the local class or shared class. To change the configurations, you need to first delete all the GDS settings on the guest OS, change the virtual SCSI device configurations, and then configure the GDS settings on the guest OS again.

Example. If disk mirroring is to be executed:
In this example, mirror group group0003, which consists of physical disks sdc and sdd, is created, and mirrored volume volume0003 is created in group0003.
