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:
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.
The PHY exists in the expander but is not connected, by design
.
