• Loop Detected - 0x00000001
• Unaddressable device exists- 0x00000002
• Multiple Ports - 0x00000004
• Expander Error - 0x00000008
• SMP Timeout - 0x00000010
• Out of route entries - 0x00000020
• SMP Response Index Does Not Exist - 0x00000040

• SMP CRC error - 0x00000100
Device Identifier Indicates the ASCII device identifier string extracted from the
device's inquiry data.
Scan Order Indicates the scan order for this device. This is equivalent to the
SCSI ID value in parallel SCSI configurations.
Device Information Indicates whether a device is SAS.
SAS Address Indicates the SAS address of the device.
Link Error Settings Number of invalid
DWORDs received outside
Invalid DWORDs
of PHY reset sequences
since the last PHY link error
reset.
Loss of DWORD Sync Number of times that
DWORD synchronization
was lost and the link reset
sequence occurred since the
last PHY link error reset.
Running Disparity Errors Number of dwords with
running disparity errors
that have been received
outside PHY reset
sequences since the last
PHY link error reset.
PHY Reset Errors Number of times the PHY
reset sequence has failed
since the last PHY link error
reset.
Error counts stop when they reach the maximum value.
Link Error Count Actual link error count values since the last PHY Link Error Reset.
a
Threshold Count Link error count threshold values. When a link error count exceeds
the threshold count within the threshold time, the MPT firmware
may reduce the link rate. You can modify the threshold values on
the Advanced Adapter Properties screen.
Threshold Time Time, in seconds, over which to apply Threshold Count. When a
link error count exceeds the threshold count within the threshold
time, the MPT firmware may reduce the link rate. You can modify
the threshold values on the Advanced Adapter Properties screen.
