show expander-status


Description	Shows diagnostic information relating to SAS Expander Controller physical channels, known as PHY lanes. NOTE:This command is for use by or with direction from technical support. For each enclosure, this command shows status information for PHYs in I/O module A and then I/O module B
Minimum role	monitor
Syntax	show expander-status
Output	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 “--”. `phy phy-ID` The logical PHY number. Type: Drawer0-Egress: Drawer 0 egress PHY Drawer0-Ingress-0: Drawer 0 ingress PHY 0 Drawer1-Egress: Drawer 1 egress PHY Drawer1-Ingress: Drawer 1 drawer ingress PHY Drawer2-Egress: Drawer 2 egress PHY Drawer2-Ingress: Drawer 2 ingress PHY Drive: Drive slot PHY Egress: Expansion port egress PHY Expander-Egress-0: Expansion port 0 egress PHY Expander-Egress-1: Expansion port 1 egress PHY Expander-Ingress-0: Expansion port 0 ingress PHY Expander-Ingress-1: Expansion port 1 ingress PHY Ingress: Expansion port ingress PHY Inter-Exp: Inter-Expander PHY SC: Storage Controller PHY SC-0: Storage Controller primary PHY SC-1: Storage Controller alternate PHY SC-a: Storage Controller alternate PHY SC-p: Storage Controller primary PHY SCA-A: Storage Controller A alternate PHY SCA-P: Storage Controller A primary PHY SCB-A: Storage Controller B alternate PHY SCB-P: Storage Controller B primary PHY 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. 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
