•
Current Speed—D
isplays the current negotiated data transfer rate for a SCSI physical drive. The
possible values are:
•
Asynchronous—The negotiated data transfer rate for this drive is asynchronous.
•
Fast—The negotiated data transfer rate for this drive is 20 megabytes per second.
•
Ultra—The negotiated data transfer rate for this drive is 40 megabytes per second.
•
Ultra2—The negotiated data transfer rate for this drive is 80 megabytes per second.
•
Ultra3—The negotiated data transfer rate for this drive is 160 megabytes per second.
•
Ultra320—The negotiated data transfer rate for this device is 320 megabytes per second.
•
Unknown—The agent is unable to determine the negotiated data transfer rate for this drive.
NOTE:
If the negotiated data transfer width is Narrow (8 bits), the actual data transfer rate is equal
to half the negotiated data transfer rate. For example, if the current negotiated data transfer rate is
Ultra (40 megabytes per second) and the width is Narrow, then the actual data transfer rate is 20
megabytes per second.
•
Placement—Indicates whether the physical drive is in an internal or external storage system. The following
values are valid:
•
Internal—The physical drive is in an internal storage system.
•
External—The physical drive is in an external storage system.
•
Unknown—The physical drive is not in a storage system or the Storage Agents cannot determine the drive
placement.
This symbol indicates that the drive is a hot plug drive.
•
Rotational Speed—Indicates the rotational speed of the drive in revolutions per minute.
•
Drive Type—Indicates the type of physical drive. The following values are valid:
•
SCSI—The physical drive is a parallel SCSI drive.
•
SATA—The physical drive is a Serial ATA drive.
•
SAS—The physical drive is a Serial attached SCSI drive.
•
Unknown—The Storage Agents cannot determine the drive 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.
