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.

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.

•

Undefined

: No status information is available.

•

Unused

: Unused 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.

•

: 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.
