DX Object Storage Platform: Advanced Node ConfigurationPage 2IntroductionThe DellTM DX Object Storage Platform provides configuration of cluster-wide parameters through theweb-based management console on the DX Cluster Services Node (CSN). There are additional nodelevel configurations that are not supported through the web-based management console and requireadvanced knowledge of the node configuration files located on the DX Cluster Services Node. Thisdocument provides instructions on configuring the following advanced configurations through the nodeconfiguration files: Configuration of Sub-clusters Configuration of Storage Nodes in archive modeThe target audience for this document is advanced DX Storage administrators and support teams.Storage Node Configuration FileAll cluster-wide Storage Node configurations should be done through the CSN Console. Theconfiguration parameters are stored in a single configuration files (/var/opt/caring/netboot/content/common.cfg) that is automatically generated. DX Storage also allows Storage Node level configuration.Node level configuration is not supported through the CSN console. It requires manual editing ofconfiguration files located on the CSN. There is an individual Storage Node configuration file for everySN in the cluster that can be modified to define custom configuration for each storage node.The configuration file can be manually created and stored on the CSN. . The file associated with anindividual Storage Node should be given the name of the Storage Node machine (MAC) address(snMACAddress.cfg) and should be located in the /var/opt/caringo/netboot/content/nodeconfigs/directory. Since the Mac address is not assigned until after the Storage Node has boot into the cluster,the Storage Node configuration file cannot be created until after the Storage Node boots into thecluster. To assist in creating the individual Storage Node (SN) configuration files, a list of all IP addressassignments and the associated Storage Node MAC address can be obtained by running the followingcommand line script:# /opt/caringo/csn/bin/ip-assignmentsTo create custom config files for every known MAC address automatically run following command:# for mac in `/opt/caringo/csn/bin/ip-assignments --macs`; do touch/var/opt/caringo/netboot/content/nodeconfigs/sn$mac.cfg; doneBelow is a summary of the steps for creating and updating the configuration file for a Storage Node:1. PXE boot the SN.2. Identify the SN MAC address and create the configuration file via the /opt/caring/csn/bin/ip-assignments script3. Modify the snMACAddress.cfg file for that SN.4. Reboot the SN.
