Model displays the model of the device.
Firmware Revision displays the firmware version of the device.
The information displayed for each IDE ATA disk drive entry in the submenu includes condition graphic and disk drive location: Primary or Secondary channel, Master device 0 or Slave device 1. If the Storage Agents cannot determine the channel then Channel unknown will be displayed. If the device position cannot be determined then Device unknown will be displayed. You may need to upgrade your driver software or the Storage Agents. Select any of the disk drives from the submenu to display more information about the disk drives. The following information is displayed for all disk drives:
Model displays the model of the disk drive.
Status displays the current status of the disk drive. The following values are valid:
OK - The disk drive is operating normally.
S.M.A.R.T. Error - The S.M.A.R.T. predictive failure monitoring predicts imminent failure of this disk drive. Schedule replacement before actual failure occurs.
Failed - The disk drive has failed and needs to be replaced.
Unknown - The Storage Agents cannot determine the status of the disk drive. You may need to upgrade your driver software or Storage Agents.
S.M.A.R.T. Support indicates whether S.M.A.R.T. support is available for this disk drive. The following values are valid:
Available - This drive supports predictive failure monitoring.
Not Available - This drive does not support predictive failure monitoring.
Unknown - The Storage Agents cannot determine if the drive supports predictive failure monitoring. You may need to upgrade your driver or Storage Agents.
Serial Number displays the serial number of the disk drive.
Firmware Revision displays the firmware version of the disk drive.
Capacity (MB) displays the capacity of the drive in megabytes. For example, 210 identifies a 210-megabyte drive. A megabyte is defined as 1,048,576 bytes. The capacity value shown may differ from the stated size of the drive due to different definitions of a megabyte. Many hardware manufacturers use the value of 1,000,000 for megabyte instead of 1,048,576.
Transfer Mode displays the data transfer mode of the disk drive. The following values are valid:
PIO Mode 0 - The data transfer mode is programmed input/output mode 0.
PIO Mode 1 - The data transfer mode is programmed input/output mode 1.
PIO Mode 2 - The data transfer mode is programmed input/output mode 2.
PIO Mode 3 - The data transfer mode is programmed input/output mode 3.
PIO mode 4 - The data transfer mode is programmed input/output mode 4.
DMA Mode 0 - The data transfer mode is direct memory access mode 0.
DMA Mode 1 - The data transfer mode is direct memory access mode 1.
DMA Mode 2 - The data transfer mode is direct memory access mode 2.
Ultra DMA Mode 0 - The data transfer mode is ultra direct memory access mode 0.
Ultra DMA mode 1 - The data transfer mode is ultra direct memory access mode 1.
Ultra DMA Mode 2 - The data transfer mode is ultra direct memory access mode 2.
Ultra DMA Mode 3 - The data transfer mode is ultra direct memory access mode 3.
Ultra DMA Mode 4 - The data transfer mode is ultra direct memory access mode 4.
Ultra DMA Mode 5 - The data transfer mode is ultra direct memory access mode 5.
Unknown - The Storage Agents cannot determine the disk drive data transfer mode.
This is a list of logical drives that includes this physical drive as a member. Select one of the listed logical drives to see more information about the drive.
A list of logical drives associated with the controller displays in the Mass Storage submenu. Each logical drive in the list displays the condition, logical drive number and the fault tolerance of that logical drive. Select one of the logical drive entries to display the following information.
Status displays the status of the logical drive. The logical drive can be in one of the following states:
OK - Indicates that the logical drive is in normal operation mode.
Degraded - Indicates that at least one physical drive has failed, but the logical drive's RAID level lets the drive continue to operate with no data loss.
Rebuilding - Indicates that the logical drive is rebuilding a physical drive. When complete, the logical drive will return to normal operation.
Failed - Indicates that more physical drives have failed than the RAID level of the logical drive can handle without data loss.
Unknown - The agent cannot determine the logical drive status. You may need to upgrade your software.
Fault Tolerance displays the fault tolerance mode of the logical drive. The following values are valid:
RAID 0 - Fault tolerance is not enabled. You will experience data loss for that logical drive if one physical drive fails.
RAID 1 - Drive 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. This is the most costly fault tolerance method because it requires 50 percent of the drive capacity to store the redundant data. If a physical drive fails, the mirror drive provides a backup copy of the files and normal system operations are not interrupted.
RAID 0+1 - Drive mirroring is the highest level of fault tolerance. There must be four drives for RAID 0+1. This is the most costly fault tolerance method because it requires 50 percent of the drive capacity to store the redundant data. If a physical drive fails, the mirror drive provides a backup copy of the files and normal system operations are not interrupted. This mirroring feature can withstand multiple simultaneous drive failures as long as the failed drives are not mirrored to each other.
Unknown - The agent cannot determine the RAID level of this logical drive. You may need to upgrade your software.
Capacity displays the size of the logical drive in megabytes. For example, 120 indicates that the logical drive is 120 megabytes. Use this data to determine whether the drive will be large enough to accommodate your needs.
The capacity utility defines a megabyte as 1,048,576 bytes. The capacity value shown may differ from the stated size of the drive due to different definitions of a megabyte. Many hardware manufacturers use the value of 1,000,000 for megabyte instead of 1,048,576.
Stripe Size displays the size of a logical drive stripe in kilobytes.
Disk Rebuilding identifies the physical drive that is being rebuilt. The identity of the physical drive will only be displayed when the status of the logical drive is Rebuilding otherwise N/A will be displayed.
This is a list of physical drives that make up the logical drive. Select one of the listed physical drives to see more information about the drive.
This is a list of physical drives that can be used to replace a failed physical drive if the fault tolerance mode is RAID 1 or RAID 0+1. Select one of the listed spare drives to see more information about the drive.
