A.12.2 When building a cluster system between guest OSes on multiple host OSes

System configuration

Network configuration example

Note

Set the host OS as an NTP server and the guest OS as an NTP client, and then perform time synchronization.
If you plan to operate guest OSes on multiple host OSes as clusters, use NTP for time synchronization on the host OS as well.
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 "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function."

System disk settings

Host OS	Node name	Virtual disk name	Slice number	Slice name	Size (MB)
host01	primecl01	hda	1	/	15374
			2	/boot/efi	256
			3	swap	2048
	primecl11	hda	1	/	15374

			3	swap	2048

Note

If you want to mirror the system disk by using GDS, see "PRIMECLUSTER Global Disk Services Configuration and Administration Guide."

Shared disk array settings

Device name: ETERNUS	Number of LUN	Number of RAID groups	RAID level	Size
Device name: ETERNUS	6	6	5	248.2GB

Note

The local class disks or shared class disks used by GDS on the guest OS should be created as virtual disks (virtio-SCSI devices or virtio block devices) if they are used in the virtual machine environment.

Shown below is an example of the Cluster Configuration Worksheet.
