HP 8 INT Port SAS/SATA HBA
HP 4 INT Port SAS/SATA HBA
Unknown - You may need to upgrade your driver software or Storage Agents or you have a SAS HBA in the system that the Storage Agents do not recognize.
Serial Number displays the serial number of the SAS HBA. This number can be used for identification purposes.
OK - The host bus adapter is operating normally.
Failed - The host bus adapter has failed and is no longer operating.

Serial Number displays the serial number assigned to the physical drive. This value is based on the serial number as returned by the SCSI inquiry command, but may have been shortened due to space limitations. Use this item for identification purposes.
Capacity displays the size of the physical drive. A megabyte (MB) is 1,048,576 bytes, a gigabyte (GB) is 1,073,741,824 bytes, and a terabyte (TB) is a thousand gigabytes.
Many hardware manufacturers use a megabyte value of 1,000,000 instead of 1,048,576. This may result in discrepancies between the manufacturer's stated size and the size reported by this application.
Firmware Version displays the firmware revision level of the SAS physical drive.
Placement indicates if 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.
Disk Type indicates the type of disk drive. The following values are valid:
SAS - The disk is a serial SCSI disk drive.
SATA - The disk is a Serial ATA disk drive.
Unknown - The Storage Agents cannot determine the disk type.
SAS Address displays the SAS address assigned to this disk drive. This item can be used for identification purposes.
Rotational Speed indicates the rotational speed of the drive in revolutions per minute.
Used Reallocs displays the number of sectors of the reallocation area that have been used by the physical drive.
OS Assigned Name displays the operating system name associated with this disk drive.
Select a SAS logical drive from the SAS host bus adapter submenu to display the following information:
Status shows the status of the physical drive selected.
OK - The logical drive is in normal operation mode. No user action is required.
Degraded - The logical drive is in a degraded state.
Failed - There are more failed physical drives than the fault tolerance mode of the logical drive can handle without data loss.
Unknown - The Storage Agents cannot determine the status of this drive. You may need to upgrade your driver software or Storage Agents.
Raid Level displays the raid configuration of the logical drive. The possible values are:
RAID 0 - fault tolerance is not enabled. If a physical drive reports an error, the data cannot be recovered.
RAID 1 - Mirroring is the highest level of fault tolerance. It is the only method offering fault tolerance protection if no more than two physical drives are selected. Drive mirroring creates fault tolerance by storing duplicate data on two drives. There must be an even number of drives. This is the most costly fault tolerance method because it requires 50 percent of the drive capacity to store the redundant data.
Unknown - The Storage Agents cannot determine the raid configuration of this logical drive. You may need to upgrade your driver software or Storage Agents.
Capacity displays the size of the logical drive. A megabyte (MB) is 1,048,576 bytes, a gigabyte (GB) is 1,073,741,824 bytes, and a terabyte (TB) is a thousand gigabytes.
Drive manufacturers sometimes use the number 1,000,000 as a megabyte when giving drive capacities so this value may differ from the advertised size of a drive.Stripe Size The size of a logical drive stripe or group of data written to a physical drive in kilobytes. It may be zero in some raid configurations.
OS Assigned Name displays the operating system name associated with this logical drive.
When the status is Rebuilding the following will be displayed to indicate the progress of the operation.
Percent Rebuild Complete displays the percent complete of the rebuild. When the value reaches 100, the rebuilding process is complete. The drive array continues to operate in interim recovery mode while the drive is rebuilding.
Rebuilding Drive identifies the physical drive that failed. The logical drive is rebuilding using a spare drive in place of this failed drive.
Physical Drives
A list of physical drives that are members of this logical drive. Select one of the listed physical drives to see more information about the drive.
Spare Drives
A list of spare drives that may be used by this logical drive to replace a failed drive. Select one of the listed spare drives to see more information about the drive.

Drive Bays displays the number of drive bays provided by this storage system. If duplexing hardware is used with the storage system, the drive bay number is less than the number of physical drive bays in the enclosure.
Fan Status displays the status of the fan subsystem in the drive enclosure, or box. The following values are possible:
Power Supply Status displays the status of the redundant power supply. The following values are possible:
OK - The fan subsystem is working properly.
Failed - A fan has failed and there are not enough fans in the fan subsystem to keep the enclosure cool. Check your fan subsystem as soon as possible. Continued operation may cause failure of the drives.
Degraded - A fan has failed but there are still enough fans in the fan subsystem to keep the enclosure cool.
Unknown - The Storage Agents do not recognize the status of the fan subsystem. You may need to upgrade your software.
No Fan - This storage system does not have a fan.
OK - All component power supplies that make up the redundant power supply are in normal working order.
Degraded - One of the component power supplies that make up the redundant power supply has failed. The drive system (either a drive subsystem or a power supply for the main unit) continues to operate. However, if the remaining power supply should fail, the drive system will lose all power and data loss could occur. To correct this situation, schedule a time to bring the device down and replace the failed power supply.
Unknown - The Storage Agents do not recognize the redundant power supply. You may need to upgrade your software.
No Redundant Power Supply - This storage system does not support a redundant power supply.
