8.12.1 Adding Hardware

This section describes how to add hardware.

8.12.1.1 Adding the shared disk device

The following describes how to add the shared disk device.

Figure 8.11 Procedure to add the shared disk device

Information

You must stop RMS during performing "5. Change the cluster configuration."

However, you do not need to stop RMS if all the following conditions are met because performing "5. Change the cluster configuration" is not necessary under the condition:

• The added shared disk device is registered with the existing class of GDS.

• The added shared disk device is no used as Fsystem resource.

Operation Procedure:

1. Add the shared disk device.

   See "9.2 Maintenance Flow" and ask your Fujitsu customer engineer (CE) to add the shared disk device.

2. Recognize the hot-added shared disk devices (RHEL6 or later)

   When the shared disk devices are hot-added on RHEL6 or later version, the following setting is required for all the nodes that include the hot-added shared disk devices.

   # /etc/opt/FJSVsdx/bin/sdx_by_id replace device_name 

   Example

   When the names of the hot-added disk devices are sdf, sdg, and sdh

   # /etc/opt/FJSVsdx/bin/sdx_by_id replace sdf,sdg,sdh

3. Add resources of the shared disk device.

   Register resources corresponding to the added shared disk device to the resource database.

   See

   To register resources, see "5.1.3.2 Registering Hardware Devices."

4. Set up Gds resources.

   To use GDS, set up GDS and create Gds resources.

   If you register the added shared disk device with the existing class of GDS, you do not need to set Gds resources.

   See

   For information on how to set up GDS and create Gds resources, see "6.3 GDS Configuration Setup," "6.7.3.3 Preliminary Setup for Gds Resources," and "6.7.3.4 Setting Up Gds Resources."

5. Change the cluster configuration.

   Change the cluster configuration to add the following resources related to the added shared disk device to a cluster application.

   • Fsystem resource

   • Gds resource

   See

   For information on how to change the cluster configuration, see "8.1 Changing the Cluster Configuration"

8.12.1.2 Adding a Network Interface Card Used for the Public LAN and the Administrative LAN

This section describes how to add a network interface card used for the public LAN and the Administrative LAN.

Figure 8.12 Procedure to add a network interface card

Operation Procedure:

1. Add a network interface card.

   See "9.2 Maintenance Flow" and ask your Fujitsu customer engineer (CE) to add a network interface card.

2. Add resources of the network interface card.

   Register resources corresponding to the added network interface card to the resource database.

   See

   To register resources, see "5.1.3.2 Registering Hardware Devices."

3. Change the cluster configuration.

   Change the cluster configuration to add the following resources related to the added network interface card to a cluster application.

   • Takeover network resource

   • Gls resource
