About the Hardware page

The Hardware page of the HCP System Management Console lists all the nodes in the HCP system, including HCP S Series Nodes, and provides general information about each one. If the nodes in the system are blades in Hitachi Compute Blade 320 servers, the page shows the status of the fans and power supplies in the CB 320 chassis under its own subsection labeled Chassis.

The Hardware page also shows the status of all other hardware components of the HCP system that can be monitored in the System Management Console.

To display the Hardware page, click Hardware in the top-level menu.

Note

To view the Hardware page, you need the monitor, administrator, security, service, or compliance role.

About the Nodes page

The Hardware Nodes page lists all the HCP General Nodes and HCP S Series Nodes in the HCP system. General Nodes remain listed on this page regardless of whether they are running, starting up, stopping, or not running. Nodes that have been permanently removed from the system are not displayed in the list.

For each node in the HCP system, the General Node list on the Hardware Nodes page shows:

  • Node ID

    The unique number assigned to the node.

  • Model

    The type of node. Possible models are:

    • G11

      A Hitachi Advanced Server DS220 that can exist in a RAIN or SAIN system

    • G10

      A Hitachi Advanced Server that is the predecessor to the HCP G11. A HCP G10 can exist in a RAIN or SAIN system.

    • 300

      A server other than a G11 or G10 that exists in a HCP RAIN system

    • 500

      A server other than a G11 or G10 that exists in a HCP SAIN system

    • 500XL

      A server other than a G11 or G10 that exists in a HCP SAIN system

    • VM

      A server running a HCP-VM system

  • Status

    The node status. Possible values are:

    • Available

      The node is running.

    • Unavailable

      The node is either not running, starting up but not yet able to perform HCP functions, or shutting down and no longer able to perform HCP functions. If a node is unavailable because of a hardware problem, you might be able to determine the cause by reviewing the Hardware Status section on the individual Storage Node page.

    • Migrating

      The node is available, and the Migration service is currently migrating data off the storage managed by the node.

    • Alert

      The node is unavailable, and HCP can detect which components are experiencing problems. One or more alerts identifying the problems are displayed in the Alerts column.

    NoteIf the status of a node changes from available to unavailable and the node does not restart automatically, contact your authorized HCP service provider. Do not try to restart the node manually; this action might cause the loss of information that is required to diagnose the problem.
  • Alerts

    None, one, or more icons representing components that are experiencing problems.

    For more information about any problem, click the node number.

  • Logical Volumes

    The status of the logical volumes managed by the node. Each logical volume can be one of these types:

    • Data volume

      Primary running storage that stores object data, but does not store the metadata query engine index. Primary running storage is storage that is managed by the nodes in the HCP system and consists of continuously spinning disks.

      Data volumes have numeric IDs in the range 1 (one) through 63 and 92 through 95.

    • Index volume

      (SAIN systems only) Primary running storage that stores only the metadata query engine index. All storage nodes should have the same number of index volumes.

      Index volumes have numeric IDs in the range 64 through 91.

    • Shared volume

      Primary running storage that stores both object data and the metadata query engine index. All storage nodes have one shared volume.

      The shared volume for each node has a numeric ID in the same range as data volumes.

    • Spindown volume

      (SAIN systems only) Primary spindown storage that is used for tiering purposes. Primary spindown storage is storage that is managed by the nodes in the HCP system and consists of disks that can be spun down and spun up as needed. Primary spindown storage stores object data, but it does not store the metadata query engine index. All storage nodes should have the same number of spindown volumes.

      Spindown volumes have numeric IDs in the range 96 through 127. The volume numbering starts at 96.

      A SAIN system can have spindown volumes only if both of these conditions are true:

      • One or more logical volumes used by the system are capable of being spun down. This means that they are on storage systems that support spindown.
      • The system is configured to use one or more spindown-capable logical volumes as primary spindown storage.
    • NFS volume

      (also called an external volume) Extended storage that is accessed using an NFS mount point. Extended storage is storage that is managed by devices outside of the HCP system and is used for storage tiering. NFS storage is one of six types of extended storage that you can configure HCP to use. NFS storage can be used to store object data only.

      NFS volumes have numeric IDs in the range 96 through 127. The volume numbering starts from 127 and goes down.

    • Database volume

      A volume that holds database transaction logs and indexes. Optional rear mounted SSD volumes are also available for G10 and G11 nodes. SSD volumes store only indexes.

    The Logical Volumes column displays a status icon for each logical volume managed by the node. The hover text for each icon shows the volume type, volume ID, and, for NFS volumes, the share path and the name of the extended storage pool that contains the NFS volume.

    The next table describes the logical volume status icons.

    Broken — HCP can cannot mount the volume. Possible reasons include the exported share is not configured correctl, or the NFS server is not running on the device. Check the export configuration and verify that the NFS server is running. If the configuration is correct and the NFS server is running, ensure that the device is functioning properly and that the network connecting HCP to the device is healthy.

    If this status persists, contact your authorized HCP service provider.

    External Unavailable iconNFS (External)

    Unavailable — HCP is in the process of mounting, updating, or deleting the volume. If you just created or updated the volume and the volume status does not quickly change to available or broken, try remounting the volume.

    If this status persists, contact your authorized HCP service provider for help.

    The following information applies to the logical volume display:

    • Each node also has a logical volume for the operating system; however, that logical volume is not included in this display.
    • For HCP SAIN systems that also have internal storage, this display does not include the logical volumes on the internal drives.
    • When a logical volume is removed from a node, the System Management Console might not show the change immediately. Heavy read or write activity causes more access to HCP storage and results in faster detection of the volume removal.
  • Volume Usage

    A graphical representation of the amount of primary storage currently in use compared to the total amount of primary storage that is managed by the node. The Volume Usage column also displays text indicating the total number of bytes of primary storage and the percent of primary storage space that is currently in use.

For each node that was permanently removed from the system, the first column in the display shows Removed.

For each HCP S Series Node associated with the HCP system, the S Series Nodes list on the Hardware Nodes page shows:

  • Name

    The name of the S Series Node.

  • Serial Number

    The serial number of the HCP S Series Node.

  • Model

    The type of S Series Node. Possible models are:

    • S11
    • S11
    • S30
    • S31
  • Status

    The node status. Possible values are:

    • Normal

      The S Series Node is running and has no problems that require attention.

    • Degraded

      The S Series Node has one or more noncritical problems that may require attention.

    • Critical

      The S Series Node has one or more critical problems that require attention.

    • Unavailable

      The S Series Node is either not running, starting up but not yet able to perform functions, or shutting down and no longer able to perform functions. If an S Series Node is unavailable dbecause of a hardware problem, you might be able to determine the cause by reviewing the Hardware Status section on the individual Overview page.

  • Alerts

    None, one, or more icons representing components that are experiencing problems.

  • Capacity

    A graphical representation of the amount of storage that is currently in use compared to the total amount of storage that is on the node. The Capacity column also displays text indicating the total number of bytes of storage and the percent of storage space that is currently in use.

Monitoring individual HCP general nodes

Each HCP general node has its own page on the HCP System Management Console that shows detailed information about the node. The page title indicates the node number and the node status.

Before you begin

To view an individual HCP general node page, you need the monitor, administrator, security, service, or compliance role.

Procedure

  1. Go to the Hardware Nodes page.

  2. Click the node that you want to examine.

Monitoring individual HCP S Series Nodes

The Overview panel on the page for an individual HCP S Series Node provides information about various components of the node. The pie chart at the top right of the page shows the total storage capacity of the S Series Node (dark blue) and the total storage capacity used (light blue).

The Server Modules section lists the names and statuses of HCP S Series Node server modules. Server modules run the software that manages the HCP S Series Node, provide data access, and ensure data protection.

The Enclosure section lists names and statuses of S Series Node enclosures. The enclosure is a container for the power, cooling, and server modules, along with the hard disk drives inside the node. S11 nodes have only one enclosure. S30 nodes support up to 16 enclosures.

The Events section shows the messages about warning-level and error-level alerts that occur on the HCP S Series Nodes. The messages in this panel are a subset of all the messages on the HCP system log.

To see more detailed information about the HCP S Series Node, click the HCP S Series Node URL located above the pie chart. This opens the HCP S Series Management Console.

About the Switches page

On the Hardware Switches page you can add, delete, and monitor your HCP system switches. With the Service role enabled you can add and delete switches. With the Administrator role you can monitor the status of existing switches, but you cannot add or delete them.

For each switch, the page displays the following information:

  • Type

    The type of component.

  • Model

    The make and model of the component (for example, Dell® PowerConnect 2824).

  • IP address

    The IP address of the switch.

  • Status

    The status of the component. Possible values are:

    • Normal

      The component is available and functioning properly.

    • Warning

      The component has detected an error. For switches, possible causes include:

      • A fan in the switch is not operating normally.
      • A sensor in the switch is detecting an abnormal temperature.
      • One of two power supplies in the switch is not connected.
      • One or more ports in the switch are malfunctioning.
    • Unavailable

      HCP does not have connectivity to the component.

      HCP also reports a component as unavailable if it has not yet contacted the component for status information. To determine whether this is the reason for the unavailable status, refresh the Hardware Switches page in five minutes.

    If the status of a component is unhealthy or if a component remains unavailable for more than five minutes, contact your authorized HCP service provider for help.

Adding a switch

Procedure

  1. Click the drop down menu located in the top right of the Switches tab and select the switch type you want to add.

  2. Click Add.

    A new switch, highlighted in green, appears in the window.

  3. Click the Model drop down menu in the new switch, and select the applicable model.

  4. Type the IP address.

  5. Click Update Settings.

Next steps

Switches can be deleted by clicking the garbage can icon on the left hand side of the switch and confirming that you want the switch removed.

About the Chassis tab

For HCP SAIN systems that use CB 320 servers, the Hardware Chassis page shows the IPMI sensor information for the fans and power supplies on the server chassis.

Note

HCP uses SNMP to retrieve the IPMI sensor information from the CB 320 servers. To enable this, for each server, you need to add the lowest-numbered storage node in the HCP system to the list of SNMP managers in the server configuration. To identify the node, use a valid network IP address for the node. For the community name, use public.

If the lowest-numbered node changes at any time (for example, because of prolonged node unavailability or the addition of a node with a lower number), you need to update the each CB 320 server configuration accordingly.

For information about configuring CB 320 servers, see the applicable Hitachi documentation.
