Install the software required for PRIMECLUSTER on each node.
The explanation is divided into the following topics:
Installation and configuration of related software
Installation and environment configuration of applications
After installing the software related to PRIMECLUSTER, you need to take it into operation and make various settings for the OS and the hardware.
Perform the following steps as necessary
Installation of VMware vSphere
Take the following steps to set system disks and related devices, shared disks and related devices, and the virtual network.
Setting up system disks and related devices
When you create a new virtual machine by using vSphere Client or vSphere Web Client, select [Eager Zeroed] to set provisions of the system disk.
For types of SCSI controllers, set to "LSI Logic Parallel" or "VMware Paravirtual".
Set to "No" for sharing of the SCSI bus.
Setting up shared disks
When creating the first virtual machine, create shared disks taken over in the cluster system with Raw DeviceMapping (RDM). For the second virtual machine, select "Use an existing virtual disk" and specify the first RDM disk you created.
Set the compatibility mode of share disks to "Virtual."
The virtual disks should use new SCSI controllers different from which used by system disks.
(Example: For the SCSI disk [SCSI(X:Y)], X indicates the controller number, and Y indicates the disk number. When the virtual device node of system disk is [SCSI(0:0)], do not use the virtual device node with the controller number 0 [SCSI(0:Y)]. Use [SCSI(1:0)] etc.)
Set the controller number and the disk number of virtual device nodes to be consistent among all the nodes that configure the cluster system.
For types of SCSI controllers, set the same type as the system disk on a guest OS.
Set to "Virtual" for sharing of the SCSI bus.
Setting up the virtual network
When creating the virtual machine, create at least two network systems for the cluster interconnect.
NTP settings (Guest OS)
These settings serve to synchronize the time of each node in the cluster system configuration. Be sure to make these settings when you configure the cluster.
Make these settings on the guest OS before you install PRIMECLUSTER.
Guest OS settings (Guest OS)
Take the following steps to set the guest OS.
File system settings for system volume
If an I/O device where the system volume is placed fails, a cluster failover does not occur and the system operation may continue based on the data stored on the memory.
If you want PRIMECLUSTER to trigger a cluster failover by panicking a node in the event that an I/O device where the system volume is placed fails, set the ext3 or the ext4 file system to the system volume and perform the following setting.
Specify "errors=panic" to the mount option of each partition (the ext3 or the ext4 file system) included in the system volume.
Example: To set it in /etc/fstab (when /, /var, and /home exist in one system volume)
LABEL=/ / ext3 errors=panic 1 1 LABEL=/boot /boot ext3 errors=panic 1 2 LABEL=/var /var ext3 errors=panic 1 3 LABEL=/home /home ext3 errors=panic 1 4
However, an immediate cluster failover may not become available due to taking time for an I/O error to reach the file system. The regularly writing to the system volume enhances the detection frequency of I/O error.
Network settings
In the guest OS in the cluster system, it is necessary to make network settings such as IP addresses for the public LAN and the administrative LAN.
Implement these settings on the guest OS that you are going to run as a cluster.
Installation of PRIMECLUSTER (Guest OS)
For installing PRIMECLUSTER, an installation script (CLI Installer) is available.
This script method installs PRIMECLUSTER node by node on systems that already have Linux(R) and related software installed. It is also utilized for installation on cluster management servers.
See
For details on the installation procedure, see the Installation Guide for PRIMECLUSTER.
Checking and setting the kernel parameters
Depending on the environment, the kernel parameters must be modified.
All the nodes on which PRIMECLUSTER is to be installed
Depending on the utilized products and components, different kernel parameters are required.
Check the Kernel Parameter Worksheet and modify the settings as necessary.
See
For details on the kernel parameters, see "A.6 Kernel Parameter Worksheet."
Note
To activate the modified kernel parameters, restart the guest OS after installation and settings for related software are complete.
Install applications products to be operated on the PRIMECLUSTER system and configure the environment as necessary.
See
For details on environment setup, see manuals for each application.
For information on PRIMECLUSTER-related products supporting VMware, see the documentation for each product.
