Viewing information about an appliance Storage Node

You can view information about an appliance Storage Node at any time. For example, you might want to review appliance-specific information to ensure correct configuration and status.

Before you begin

About this task

Each StorageGRID Webscale appliance is represented as one Storage Node.

The Nodes page lists information about service health and all computational, disk device, and network resources for each appliance Storage Node. You can also see memory, storage hardware, network resources, network interfaces, network addresses, and receipt and transmittal information.

Note: To view this information on the Nodes page, you must be using StorageGRID Webscale 11.1.1. If you are using StorageGRID Webscale 11.1.0, select Support > Grid Topology > appliance Storage Node > SSM > Resources to view similar information.

Steps

  1. Select Nodes.
  2. Select an appliance Storage Node.
  3. Select Overview.
    The Node Information table on the Overview tab displays the name of the node, the node type, the software version installed, and the IP addresses associated with the node. The Interface column contains the name of the interface. An eth interface is a Grid Network, Admin Network, or Client Network, hic is a bonded port, and mtc (not shown in the following screen shot) is for management IP addresses on the appliance.

  4. Select Hardware to see more information about the appliance.
    1. View the CPU Utilization and Memory graphs to determine the percentages of CPU and memory usage over time. To display a different time interval, select one of the controls above the chart or graph. You can select to display the information available for intervals of 1 hour, 1 day, 1 week, 1 month, or 1 year. Or you can set a custom interval, which allows you to specify date and time ranges.

      Hardware Graphs
    2. Scroll down to view the table of components for the appliance. This table contains information such as the model name of the appliance; controller names, serial numbers, and IP addresses; and the status of each component.
      Note: Some fields, such as Compute Controller BMC IP and Compute Hardware, appear only for appliances with that feature.

      Nodes Page SG Appliance Hardware
      Field Description
      Appliance Model The model number for this StorageGRID Webscale appliance shown in SANtricity software.
      Storage Controller Name The name for this StorageGRID Webscale appliance shown in SANtricity software.
      Storage Controller A Management IP IP address for management port 1 on storage controller A.

      You use this IP to access SANtricity software to troubleshoot storage issues.

      Storage Controller B Management IP IP address for management port 1 on storage controller B.

      You use this IP to access SANtricity software to troubleshoot storage issues.

      Storage Controller WWID The worldwide identifier of the storage controller shown in SANtricity software.
      Storage Appliance Chassis Serial Number The chassis serial number of the appliance.
      Storage Hardware The overall status of the storage controller hardware.

      If the Storage Node is a StorageGRID Webscale appliance and it needs attention, then both the StorageGRID Webscale and SANtricity systems indicate that the storage hardware needs attention.

      If the status is "needs attention," first check the storage controller using SANtricity software. Then, ensure that no other alarms exist that apply to the compute controller.

      Storage Controller Failed Drive Count The number of drives that are not optimal.
      Storage Controller A The status of storage controller A.
      Storage Controller B The status of storage controller B.

      Some appliance models do not have a storage controller B.

      Storage Controller Power Supply A The status of power supply A for the storage controller.
      Storage Controller Power Supply B The status of power supply B for the storage controller.
      Storage Multipath Connectivity The multipath connectivity state.

      For details about resolving performance or fault tolerance issues, refer to the E-Series documents.

      Overall Power Supply The status of all power supplies for the appliance.
      Compute Controller BMC IP The IP address of the baseboard management controller (BMC) port in the compute controller.

      You use this IP to connect to the BMC interface to monitor and diagnose the appliance hardware.

      This field is not displayed for appliance models that do not contain a BMC.

      Compute Controller Serial Number The serial number of the compute controller.
      Compute Hardware The status of the compute controller hardware.

      This field is not displayed for appliance models that do not have separate compute hardware and storage hardware.

      Compute Controller CPU Temperature The temperature status of the compute controller's CPU.
      Compute Controller Chassis Temperature The temperature status of the compute controller.
      Compute Controller Power Supply A The status of power supply A for the compute controller.
      Compute Controller Power Supply B The status of power supply B for the compute controller.
    3. Confirm that all statuses are "Nominal."
      The statuses in this section correspond to the following alarm codes.
      Field Alarm code
      Storage Controller Failed Drive Count BADD
      Compute Controller Chassis Temperature BRDT
      Compute Controller Hardware CCNA
      Compute Controller Power Supply A CPSA
      Compute Controller Power Supply B CPSB
      Compute Controller CPU Temperature CPUT
      Overall Power Supply OPST
      Storage Controller Power Supply A PSAS
      Storage Controller Power Supply B PSBS
      Storage Controller A SCSA
      Storage Controller B SCSB
      Storage Hardware SOSS

      For details about alarms in StorageGRID Webscale, see the information about troubleshooting.


  5. Select Network to view information for each network.

    The Network Traffic graph provides a summary of overall network traffic.
    Nodes Page Network Traffic Graph

    1. Review the Network Interfaces section.

      Nodes Page Network Interfaces
      Use the following table with the values in the Speed column in the Network Interfaces table to determine whether the 10/25-GbE network ports on the appliance were configured to use active/backup mode or LACP mode.
      Note: The values shown in the table assume all four links are used.
      Link mode Bond mode Individual HIC link speed (hic1, hic2, hic3, hic4) Expected Grid/Client Network speed (eth0,eth2)
      Aggregate LACP 25 100
      Fixed LACP 25 50
      Fixed Active/Backup 25 25
      Aggregate LACP 10 40
      Fixed LACP 10 20
      Fixed Active/Backup 10 10

      See the installation and maintenance instructions for your appliance for more information about configuring the 10/25-GbE ports.

    2. Review the Network Communication section.
      The Receive and Transmit tables show how many bytes and packets have been received and sent across each network as well as other receive and transmission metrics.
      Nodes Page Network Comm
  6. Select Storage to view graphs that show the percentages of storage used over time for object data and object metadata, as well as information about disk devices, volumes, and object stores.

    Storage Used - Object Data

    Storage Used - Object Metadata
    1. Scroll down to view the amounts of available storage for each volume and object store.

      The Worldwide Name for each disk matches the volume world-wide identifier (WWID) that appears when you view standard volume properties in SANtricity software (the management software connected to the appliance's storage controller).

      To help you interpret disk read and write statistics related to volume mount points, the first portion of the name shown in the Name column of the Disk Devices table (that is, sdc, sdd, sde, and so on) matches the value shown in the Device column of the Volumes table.
