HCP System Management Help
The Hardware►Nodes page lists all of the HCP General Nodes and HCP S Series Nodes in the HCP system. General Nodes remain listed on this page regardless of whether they’re running, starting up, stopping, or not running at all. Nodes that have been permanently removed from the system do not appear on 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:
oG10 — A Quanta D51B-2U server which can exist in both a RAIN or SAIN system
o300 — A server other than a Quanta D51B-2U server that exists in an HCP RAIN system
o500 — A server other than a Quanta D51B-2U server that exists in an HCP SAIN system
o500XL — A server other than a Quanta D51B-2U server that exists in an HCP SAIN system
oVM — A server running an HCP-VM system
•Status — The node status. Possible values are:
oAvailable — The node is running.
oUnavailable — 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 due to a hardware problem, you may be able to determine the cause by reviewing the Hardware Status section on the individual Storage Node page.
oMigrating — The node is available, and the migration service is currently migrating data off the storage managed by the node.
oAlert — The node is unavailable, and HCP can detect which components are experiencing problems. In this case, one or more alerts identifying the problems appear in the Alerts column for the node.

Important: If the status of a node changes spontaneously from available to unavailable and the node does not restart automatically, please contact your authorized HCP service provider. Do not try to restart the node manually, as that may cause the loss of information needed to diagnose the problem. |
•Alerts — None, one, or more icons representing components that are experiencing problems. To see the text that accompanies an icon, mouse over the icon.
For more information on any problems that are occurring, click on the node number.
For information on the alerts that can appear on the Hardware►Nodes page, see Hardware page alerts.
•Logical Volumes — The status of the logical volumes managed by the node. Each logical volume can be one of these:
oData volume — Primary running storage that stores object data, but does not store the metadata query engine index. Primary running storage is storage that’s 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.
oIndex 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.
oShared 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.
oSpindown volume (SAIN systems only) — Primary spindown storage that’s used for tiering purposes. Primary spindown storage is storage that’s 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 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 from 96 and goes up.
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 arrays that support spindown.
For information on storage arrays that support spindown, see the applicable array documentation.
–The system is configured to use one or more of the spindown-capable logical volumes as primary spindown storage.
oNFS volume (also called an external volume)— Extended storage that’s accessed using an NFS mount point. Extended storage is storage that’s managed by devices outside of the HCP system and is used for storage tiering purposes. NFS storage is one of six types of extended storage that HCP can be configured 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.
oDatabase volume — A volume that holds database transaction logs and indexies. Optional rear mounted SSD volumes are also available for G10 nodes. SSD volumes store only indexes.
For information on primary running storage and primary spindown storage, see Storage tiering service. For information on the metadata query engine index, see Metadata query engine index. For information on NFS volumes and other types of extended storage, see Storage for HCP systems.
The Logical Volumes column displays a status icon for each volume managed by the node. The mouse-over text for each icon shows the volume type and ID and, for NFS volumes, the share path and the name of the extended storage pool that contains the NFS volume.
The table below describes these status icons:

Broken — HCP can cannot mount the volume, most likely because the exported share is not configured correctly or because 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. For additional possible resolutions to the problem, see NFS storage pools. If this status persists, contact your authorized HCP service provider for help. |
![]() |
NFS (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 change to available or broken within a short amount of time, try remounting the volume. If this status persists, contact your authorized HCP service provider for help. |
These considerations apply to the logical volume display:
oEach node also has a logical volume for the operating system, but that logical volume is not included in this display.
oFor HCP SAIN systems that also have internal storage, this display does not include the logical volumes on the internal drives.
oWhen a logical volume is removed from a node, the System Management Console may not show the change immediately. Heavy read or write activity causes more access to HCP storage and, therefore, results in faster detection of the volume removal.
•Volume Usage — A graphical representation of the amount of primary storage that’s currently in use compared to the total amount of primary storage that’s 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’s currently in use.
For each node that has been 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 to 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:
•Status — The node status. Possible values are:
oNormal — The S Series Node is running and has no problems that require attention.
oDegraded — The S Series Node has one or more noncritical problems that may require attention.
oCritical — The S Series Node has one or more critical problems that require attention.
oUnavailable — 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 due to a hardware problem, you may 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. To see the text that accompanies an icon, mouse over the icon.
•Capacity — A graphical representation of the amount of storage that’s currently in use compared to the total amount of storage that’s on the node. The Capacity column also displays text indicating the total number of bytes of storage and the percent of storage space that’s currently in use.
