Viewing information about appliance Storage Nodes

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.

Steps

  1. From the Nodes page, select an appliance Storage Node.
  2. Select Overview.
    The Node Information table on the Overview tab displays the node's ID and name, the node type, the software version installed, and the IP addresses associated with the node. The Interface column contains the name of the interface, as follows:
    • eth is the Grid Network, Admin Network, or Client Network
    • hic is a bonded port
    • mtc are the management IP addresses on the appliance

  3. 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 display the information available for intervals of 1 hour, 1 day, 1 week, 1 month, or 1 year. You can also 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.

      Components for the storage shelves, and expansion shelves if they are part of the installation, appear in a separate table below the appliance table.


      Nodes Page SG Appliance Hardware
      Field in the Appliance table Description
      Appliance Model The model number for this StorageGRID appliance shown in SANtricity software.
      Storage Controller Name The name for this StorageGRID 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.

      Some appliance models do not have a storage controller B.

      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 appliance and it needs attention, then both the StorageGRID 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 Data Drive Type The type of drives in the appliance, such as HDD (hard disk drive) or SSD (solid state drive).
      Storage Data Drive Size The total capacity including all data drives in the appliance.
      Storage RAID Mode The RAID mode configured for the appliance.
      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.
      Column in the Storage Shelves table Description
      Shelf Chassis Serial Number The serial number for the storage shelf chassis.
      Shelf ID The numeric identifier for the storage shelf.
      Shelf Status The overall status of the storage shelf.
      IOM Status The status of the input/output modules (IOMs) for the storage shelf. If no expansion shelves are present, the status is N/A.
      Power Supply Status The overall status of the power supplies for the storage shelf.
      Drawer Status The status of the drawers in the storage shelf. If the appliance does not contain drawers, the status is N/A.
      Fan Status The overall status of the cooling fans in the storage shelf.
    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, see the information about troubleshooting.

  4. 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
  5. 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.
