Table 101. sas-status-controller-a properties (continued)
Name Type Description
● 0: Enabled
● 1: Disabled
elem-reason string More information about the status value.
● Blank if elem-status is OK.
● Error count interrupts : PHY disabled because of error-count
interrupts.
● PHY control : PHY disabled by a SES control page as a result of action by a
Storage Controller or user.
● Not ready : PHY is enabled but not ready. Appears for SC-1 PHYs when the
partner I/O module is not installed. Appears for Drive, SC-1, or Ingress PHYs
when a connection problem exists such as a broken connector.
● Disk removed : PHY disabled because drive slot is empty.
● Unused - disabled by default : PHY is disabled by default because it
is not used.
● Excessive PHY changes : PHY is disabled because of excessive PHY
change counts.
● Did not initialize : PHY is enabled but not ready because it did not
pass COMINIT.
elem-reason-numeric uint32 Numeric equivalents for elem-reason values.
● 0 : (blank)
● 3: Error count interrupts
● 5: PHY control
● 6: Not ready
● 8: Disk removed
● 9: Unused - disabled by default
● 10: Excessive PHY changes
● 11: Did not initialize
change-counter hex32 Number of times the PHY originated a BROADCAST (CHANGE). A BROADCAST
(CHANGE) is sent if doubleword synchronization is lost or at the end of a Link
Reset sequence.
code-violations hex32 Number of times the PHY received an unrecognized or unexpected signal.
disparity-errors hex32 Number of doublewords containing running disparity errors that have been
received by the PHY, not including those received during Link Reset sequences. A
running disparity error occurs when positive and negative values in a signal do not
alternate.
crc-errors hex32 In a sequence of SAS transfers (frames), the data is protected by a cyclic
redundancy check (CRC) value. The crc-errors value specifies the number
of times the computed CRC does not match the CRC stored in the frame, which
indicates that the frame might have been corrupted in transit.
conn-crc-errors hex32 Number of times the lane between two expanders experienced a communication
error.
lost-dwords hex32 Number of times the PHY has lost doubleword synchronization and restarted the
Link Reset sequence.
invalid-dwords hex32 Number of invalid doublewords that have been received by the PHY, not including
those received during Link Reset sequences.
reset-error-counter hex32 Number of times the expander performed a reset of error counters.
flag-bits hex32 PHY status flag bits, for internal use.
