is detected, the data is rebuilt using the data from the mirrored stripes on the other
drives.
— Unknown—The Storage Agents cannot determine the fault tolerance of this logical
drive. You might need to upgrade your driver software or Storage Agents.
• Stripe Size—The size of a logical drive stripe or group of data written to a physical drive in
kilobytes. It might be zero in some fault-tolerance modes like None and Mirroring.
• Percent Rebuild Complete—Displays the percent complete of the resynchronization of the
data. When the value reaches 100, the rebuilding process is complete. The logical drive
continues to operate with slightly reduced performance during the rebuild. This value is
only active when the logical drive has a status of Rebuilding.
• OS Assigned Name—Displays the operating system name associated with this logical 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 can 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.
SCSI bus information
Select a SCSI device from the SCSI controller submenu to display more information about the
device. The following information might appear depending on the type of device:
• Parity Errors—Displays the number of parity errors that occurred on the SCSI bus while the
bus was processing commands. The error count is kept from the time the SCSI Hardware
Interface Driver was loaded.
Parity errors might occasionally occur over time. If this number rises dramatically, and you
suspect a problem, complete the following steps:
1. Ensure that the cables are not damaged and that they are intact and properly shielded
from possible RFI.
2. Ensure that all required terminating resistors on all devices on the SCSI bus are present.
3. Ensure that each device on the SCSI bus has a unique SCSI ID.
• Phase Errors—Displays the number of times the SCSI bus entered an invalid operating state
while processing commands. The number of errors is counted from the time the SCSI
Hardware Interface Driver was loaded.
If you see any phase errors, the device might have a problem. Phase errors can be caused
by a device that is not operating correctly. If the phase errors continue to increase, replace
the device.
• Select Timeouts—Displays the number of times the controller attempted to start
communications with a device and received no response from the device. The number of
errors is counted from the time the SCSI Hardware Interface Driver was loaded.
The number of select timeouts should always be 0. Any other number of timeouts might
indicate a problem with the device. The SCSI controller attempts to reset the device, but if
the value continues to increase, power cycle the device.
A large number for this item does not indicate a problem. It shows that the device does not
support certain advanced SCSI commands that the device driver issued.
• Message Rejects—Displays the number of times the device rejected a command because the
device does not support the specific operation. The number of errors is counted since the
SCSI Hardware Interface Driver was loaded.
