Encl
The enclosure that contains the SAS Expander.
Drawer
Shown in drawer output. The number of the drawer.
Expander
Shown in drawer output. The number of the Expander.
Ctlr
The I/O module that contains the SAS Expander.
Phy
Identifies the logical location of a PHY within a group based on the PHY type. If the controller module or expansion module for the PHY is not installed, this field shows “--”.
Type:
- Drive: Drive slot PHY.
- SC-P: Storage Controller primary PHY.
- SC-A: Storage Controller alternate PHY.
- Expander-Universal-0: Expansion port 0 universal PHY.
- Expander-Universal-1: Expansion port 1 universal PHY.
- Expander-Universal-2: Expansion port 2 universal PHY.
- Drawer0-Ingress-0: Drawer 0 ingress PHY 0.
- Drawer0-Ingress-1: Drawer 0 ingress PHY 1.
- Drawer0-Ingress-2: Drawer 0 ingress PHY 2.
- Drawer0-Egress-0: Drawer 0 egress PHY 0.
- Drawer0-Egress-1: Drawer 0 egress PHY 1.
- Drawer0-Egress-2: Drawer 0 egress PHY 2.
- Drawer1-Ingress-0Drawer 1 ingress PHY 0.
- Drawer1-Ingress-1: Drawer 1 ingress PHY 1.
- Drawer1-Ingress-2: Drawer 1 ingress PHY 2.
- Drawer1-Egress-0: Drawer 1 egress PHY 0.
- Drawer1-Egress-1: Drawer 1 egress PHY 1.
- Drawer1-Egress-2: Drawer 1 egress PHY 2.
Status
- Enabled - Healthy: The PHY is enabled and healthy.
- Enabled - Degraded: The PHY is enabled but degraded.
- Disabled: The PHY has been disabled by a user or by the system
Elem Status
A standard SES status for the element:
- Disabled: Critical condition is detected.
- Error: Unrecoverable condition is detected. Appears only if there is a firmware problem related to PHY definition data.
- Non-critical: Non-critical condition is detected.
- Not Used: Element is not installed in enclosure.
- OK: Element is installed and no error conditions are known.
- Unknown: Either:
- Sensor has failed or element status is not available. Appears only if an I/O module indicates it has fewer PHYs than the reporting I/O module, in which case all additional PHYs are reported as unknown.
- Element is installed with no known errors, but the element has not been turned on or set into operation.
Disabled
- Enabled: PHY is enabled.
- Disabled: PHY is disabled.
Reason
- 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.
- Firmware reboot: PHY disabled because of a firmware reboot. .
- Drive 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: HY is enabled but not ready because it did not pass
COMINIT.
Change Cnt
Shown by the
stats parameter. The 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 Viol
Shown by the
stats parameter. The number of times the PHY received an unrecognized or unexpected signal.
Disparity
Shown by the
stats parameter. The 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
Shown by the
stats parameter. 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
Shown by the
stats parameter. The number of times the lane between two expanders experienced a communication error.
Lost DWORD
Shown by the
stats parameter. The number of times the PHY has lost doubleword synchronization and restarted the Link Reset sequence.
Invld DWORD
Shown by the
stats parameter. The number of invalid doublewords that have been received by the PHY, not including those received during Link Reset sequences.
ResErrCnt
Shown by the
stats parameter. The number of times the expander performed a reset of error counters.
Flag Bits
Shown by the
stats parameter. PHY status bits, for internal use.
