Logical volume usage details


When you click on Logical volume usage, the Console displays the following information for each logical volume that’s managed by the node you’re currently viewing:

Volume ID — The logical 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 volumes are not necessarily listed in numeric order.

Status — The logical volume status. For the possible statuses, see About the Nodes page.

Capacity — The total number of bytes of storage on the logical volume.

Used — The number of bytes of storage that are currently in use on the volume. This number includes bytes occupied by parts of in-progress multipart uploads, including replaced parts, parts uploaded for aborted multipart uploads, and unused parts of completed multipart uploads until these parts are automatically deleted by the garbage collection service.

For information on multipart uploads, seeWorking with multipart uploads. For information on how the garbage collection service handles parts of multipart uploads, see Object deletions.

Percent Used — The percentage of storage space that’s currently in use on the volume.

ImportantWebHelp.png

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.

Last Status Update Time — The time of the last update to the node status.

Node ID — The number assigned to the node.

[hcp_system] — All IPv4 and IPv6 addresses assigned to the node for the [hcp_system] network.

[hcp_management] — All IPv4 and IPv6 addresses assigned to the node for the [hcp_management] network.

[hcp_backend] — The IP address assigned to the node for the [hcp_backend] network.

Boot Time — The date and time the node last started.

Usage/Capacity — The total amount of storage space on all of the primary storage volumes managed by the node and the amount of that primary storage space that’s currently in use.

Memory — The amount of RAM in the node.

Swap — The status of the swappable memory in the node:

oUsing — The amount of storage set aside for swappable memory, in GB, and the percentage of that amount that’s currently in use

oPages In — The number of pages currently swapped in

oPages Out — The number of pages currently swapped out

Load Average — The average process workload on the node over the past minute, five minutes, and 15 minutes. The load average is based on all processes, regardless of their current state (for example, running, waiting for CPU time, or sleeping).

CPU — Make and model of the CPUs in the node, listed one per line. The CPUs are numbered and are listed in numeric order starting with CPU 0.

Files systems on storage devices managed by a node


The Hardware Status section on the Storage Node page for any given node shows the number of file systems the node supports on primary storage and the number of physical storage devices to which those file systems are mapped. When you click on X file systems on Y storage devices, the Console displays the following information for each file system on the physical storage that’s managed by the node you’re currently examining:

The directory path that identifies the file system

Whether or not the file system is currently mounted

Each level of mapping that ultimately associates the file system with one or more low-level block devices

Some device diagnostic information, if available

Additional RAID-specific information, if available

Additionally, for SAIN systems, the details include this information for each low-level block device: vendor, array type, serial number, device number, and worldwide port number.

NoteWebHelp.png

Notes: 

For SAIN systems that also have internal storage, the number of file systems includes those located on the internal drives.

For SAIN systems, if multipathing is degraded, one or more of the low-level block devices will be missing from the display details.

IPMI information


Intelligent Platform Management Interface (IPMI) is a specification that defines a method of monitoring the internal hardware components of a server. If IPMI is implemented on a node, sensors in that node can detect abnormal conditions such as a high fan speed or a failed power supply.

The IPMI data that’s displayed on the Storage Node page for a given node is organized by sensor type. The list of sensors that you see for each sensor type depends on the specific IPMI implementation.

The details displayed, by sensor type, are:

Temperatures — For each temperature sensor, the current temperature reading, and for some sensors, the normal range for the temperature.

Power Supplies — For each power supply sensor, a text string read from the applicable power supply. If only one power supply is working, this section displays the message, “No redundancy.”

Fans — For each fan sensor, the current fan speed.

Processors — For each processor sensor, a text string giving the status of the applicable processor.

Voltages — For each voltage sensor, the current voltage reading.

NoteWebHelp.png

Notes: 

For fans and power supplies in CB 320 server chassis, IPMI information appears on the Hardware page. Nodes that are individual blades do not have their own fans and power supplies.

HCP does not report IPMI information for nodes in HCP-VM systems.

Network interface cards (NICs)


Each HCP node has two pairs of bonded ports:

One pair of ports is used for connecting to the front-end networks, including the [hcp_system] network and all user-defined networks. These ports share all front-end network IPv4 and IPv6 addresses assigned to the node.

One pair of ports is used for connecting to the back-end network. These ports share the back-end IP address assigned to the node.

The name assigned to each front-end and back-end port includes the NIC port number (for example, eth0 and eth1). By default, HCP uses the lower-numbered port in each bonded pair. If the lower-numbered port for a network fails, HCP automatically switches to the other port in the pair.

Optionally, depending on your HCP system hardware configuration, an HCP node may have an extra port connected to the management network. The name assigned to the management port is eth4.

On the Storage Node page for a given node, the Console displays information about each of the NICs in the node. The NIC information is organized by network. For each port assigned to a network, the Console displays these details:

Interface — The name assigned to the port.

Active — An indication of whether the port is available for use. Possible values are true and false.

Duplex — An indication of whether the port is full-duplex (full) or half-duplex (half).

Active in Bond — An indication of whether the port is currently the one being used. Possible values are true, false, and N/A.

Speed — The current rate of data transmission through the port.

Maximum Supported Speed — The maximum supported rate of data transmission for the port.

File system status


Each node in an HCP system has multiple file systems on its primary storage. At installation time, a fixed amount of space and a fixed number of inodes are allocated to each of those file systems. Each NFS volume associated with a node has a single file system with a fixed amount of space and a fixed number of inodes.

Inodes determine the total number of files and directories a file system can have. (These files and directories do not have a direct correspondence to the objects and directories that users create.)

On the Storage Node page for a given node, when you click on the row that shows the file system status summary, the Console displays the following information about each file system on each primary storage volume and NFS volume that’s managed by the node:

Path — The directory path

Free 1K Blocks — The amount of available storage associated with the file system, in one-KB blocks

Total 1K Blocks — The total amount of storage associated with the file system, in one-KB blocks

Block Usage — The percent of the storage blocks currently in use

Inode Usage — The percent of the allocated inodes currently in use

NoteWebHelp.png

Note: The file systems listed include those used for the operating system. Therefore, the total amount of storage associated with all the file systems for a node is greater than the total amount of storage associated with the logical volumes displayed for that node.

Node events


The Node Events section on the Storage Node page for a given General Node lists all event messages logged for that node since the HCP system was installed. The list of messages in this section is a subset of the messages in the HCP system log. You can view all the messages in the system log in the All Events panel on the System Events page. For more information on this panel, see Viewing the complete event log.

For a description of the information provided by each log message, see Understanding the HCP system log. For information on the messages that can appear in the system log and how to respond to them, see HCP system log messages.

By default, the messages are listed ten at a time in reverse chronological order. For information on managing the message display, see Managing the message list.
