show expander-status
Description For use by or with direction from a service technician.
Shows diagnostic information relating to SAS Expander Controller physical channels, known as PHY
lanes. 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.
