show expander-status Description Shows diagnostic information relating to SAS Expander Controller physical channels, known as PHY lanes. 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. Syntax show expander-status Output Encl Enclosure that contains the SAS expander. Ctlr I/O module that contains the SAS expander. Phy Identifies a PHY's logical location within a group based on the PHY type. Logical IDs are 0-23 for drive PHYs; 0-1 for SC PHYs; and 0-3 for other PHYs. If the PHY's controller module or expansion module is not installed, this field shows "--". Type • Drive: 1-lane PHY that communicates between the expander and a disk drive. • Egress: 4-lane PHY that communicates between the expander and an expansion port or SAS Out port. • SC-1: (Controller module only) 2-lane PHY that communicates between the expander and the partner's expander. • SC-0: (Controller module only) 4-lane PHY that communicates between the expander and the SC. • Ingress: (Expansion module only) 4-lane PHY that communicates between the expander and an expansion port. • Inter-Exp: (Expansion module only) Communicates between the expander and the partner's expander. • Undefined: No status information is available. • Unused: The PHY exists in the expander but is not connected, by design. 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. 232
