Table 66 sas-status-controller-a properties (continued) Name Type Description elem-reasonnumeric change-counter code-violations disparityerrors crc-errors conn-crc-errors lost-dwords invalid-dwords reset-errorcounter flag-bits uint32 Numeric equivalents for elem-reason values. • 0: (blank) • 32769: Error count interrupts • 32771: PHY control • 32772: Not ready • 32774: Drive removed • 32775: Unused - disabled by default • 32776: Excessive PHY changes uint32 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. uint32 Number of times the PHY received an unrecognized or unexpected signal. uint32 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 don't alternate. uint32 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. uint32 Number of times the lane between two expanders experienced a communication error. uint32 Number of times the PHY has lost doubleword synchronization and restarted the Link Reset sequence. uint32 Number of invalid doublewords that have been received by the PHY, not including those received during Link Reset sequences. uint32 Number of times the expander performed a reset of error counters. uint32 PHY status flag bits. sas-status-controller-a 449
