Agent information 43
• Unknown—The Storage Agents cannot determine the drive type.
• Media Type—Indicates the type of media the physical drive is composed of. The following values are valid:
• Rotating Platters—Indicates that the physical drive media is composed of rotating platters.
• Solid State—Indicates that the physical drive media is composed of solid state electronics.
• Unknown—Indicates that the Storage Agents cannot determine the media type.
• Negotiated Link Rate—Displays the negotiated link rate for SAS and SATA physical drives. The possible values
are:
• 1.5 Gbps—The negotiated link rate for this drive is 1.5 gigabits per second.
• 3.0 Gbps—The negotiated link rate for this drive is 3.0 gigabits per second.
• 6.0 Gbps—The negotiated link rate for this drive is 6.0 gigabits per second.
• Unknown—The agent is unable to determine the negotiated link rate for this drive.
• NCQ Support—Displays the status of Native Command Queuing support for this drive. The possible values are:
• No Controller Support—The array controller does not support NCQ.
• No Drive Support—The array controller does support NCQ, but the drive does not.
• Disabled—The array controller and drive support NCQ, but it is disabled.
• Enabled—The array controller and drive support NCQ and it is enabled.
• Unknown—The agent is unable to determine the NCQ configuration for this drive or it is not a SATA drive.
• Phy Count—Displays the number of phys for each physical drive. Single-ported drives have one phy. Dual-
ported drives have two phys.
• Multipath Status—Displays the overall multipath status of this physical drive. The following values are valid:
• Not Configured—Indicates that the physical drive is not configured to have multipath access.
• Redundant—Indicates that the physical drive currently has more than one I/O path to the controller.
• Not Redundant—Indicates that the physical drive previously had more than one I/O path to the controller
but now has no redundant I/O path.
• Disk Failed—Indicates that the physical drive has failed.
Paths
For multipath-capable hardware, the status and role of each data path to the physical drive is reported.
• Path—Indicates the path to the physical drive. Each path is identified by a descriptor, for example "Port 2E Box
1 Bay 12" indicates a path from the host adapter external port number 2 ("Port 2E") to the 12th bay in the first
box.
• Status—Indicates the status of the data path. Possible values are:
• OK—The path is operational.
• Link down—The path is not operational.
• Unknown—The path status cannot be determined.
• Role—Indicates the role of this path in the configuration. Possible values are:
• Active—This path is the preferred data path to the physical drive.
• Alternate—This path is the alternate data path to the physical drive.
• Unknown—The role of this path cannot be determined.
Identify Drive
Select the length of time to identify the physical drive from the drop-down list box and then click the Start button. The
page automatically refreshes, and then an image of an identified drive and a Stop button appears. Click the Stop
button to end identification before the time expires.
After the drive identification completes, the page must be manually refreshed to display the Start button. There may
be a delay, depending on the length of the HP Insight Management Agents data collection interval, after the drive
identification completes and before the Start button appears.
Only drives in hot plug trays are supported since the LEDs are part of the tray. Only one drive on a selected controller
may be identified at a time. If a different drive is selected while another drive is currently identified then the other
drive stops identification and the selected drive is identified.
