Procedure for memory expansion (DIMMs)
This topic describes how to expand the memory by installing additional DIMMs.
Check the total memory before adding DIMMs to the node. You can check the total memory of the node by using the support shell command from the node-level CLI, and then using any of the available system commands:
Before you add the DIMMs, in the ILO remote console, view the slots where DIMMs are not present:
To identify the management console node, in the NetBackup Flex Scale infrastructure management UI, navigate to . On the Infrastructure page, Console IP shows the management console IP address.
To shut down the cluster:
- SSH to the management console IP.
- Run the cluster shutdown all command and wait till the cluster shuts down.
- In the iLO remote console, wait until the system shows the System halted message. for each node in the cluster.
- Press the Power button on the front panel of the server or from the iLO remote console use the Server Power > Press and Hold option.
The HPE representative installs the additional DIMMs.
Below are the recommendations from HPE for DIMMs slots:
After the hardware vendor notifies you that the hardware component is installed, verify the memory on each node.
To verify that the DIMMs are installed, complete the following steps:
- Power on the all the servers together and wait till the cluster is up.
Note:
As soon as the power cable is plugged in the node, it starts automatically. So wait for DIMM replacement on all the nodes and attach power cable together.
- Run the show hardware-health command:
- After adding the DIMMs, modify bom-conf. Either 12 or 24 DIMMS are supported. By default there are 12 DIMMs per node.
Log in to node's appliance shell.
Run command support bom-conf get command.
The bom-conf file is stored in the
/system/inst/patch/incominglocationRun the support elevate command and provide the required credentials.
Go to
/system/inst/patch/incomingand edit thebom-config.jsonfile.Set DIMM to DIMM:24 and save the file.
Go to the appliance shell and run the support bom-conf update command.
Run the show hardware-health command:
- Verify the total memory of each node. You can check the total memory of the node by using the support shell command from the node-level CLI, and then using any of the available system commands:
- Check the node state. Navigate to Monitor > Infrastructure > Nodes.
- Click Dashboard and check the status of the services.
- Verify that the added DIMMs show Good, in use status in the iLO remote console.
