Reseat the disk shelf I/O module. If that does not fix the problem, replace the disk shelf I/O module.

ds.sas.element.fault

Severity

ERROR

Description

This message occurs when a Serial Attached SCSI (SAS) module in a disk shelf reports an error.

Corrective Action

Check cabling to the shelf. Check the status LED on the shelf, making sure that the fault LEDs are not on. Clear any fault condition, if possible.

Syslog Message

State of shelf module %s is %s on channels %s shelf ID %d

Parameters

element (STRING): Shelf module designator (A or B).
state (STRING): Current state of IOM.
channels (STRING): Channels that have the error if local, PARTNER for high-availability partner, UNUSED if unconnected.

ds.sas.element.xport.error

Severity

ERROR

Description

This message occurs when a Serial Attached SCSI (SAS) disk shelf module reports a transport error.

Corrective Action

Check cabling to the shelf. Check the status LED on the shelf, making sure that the fault LEDs are not on. Clear any fault condition, if possible.

Syslog Message

Shelf module %s XPORT ERROR on channels %s shelf ID %d

Parameters

element (STRING): Shelf module designator (A or B).
channels (STRING): Channels that have the error if local, PARTNER for high-availability partner, UNUSED if unconnected.
shelfID (INT): Shelf ID (0-99) of the shelf reporting the error.

ds.sas.hostphy.disableErr

Severity

ALERT

Description

This message occurs when a host physical layer device (phy) on a Serial Attached SCSI (SAS) I/O module is disabled due to one of the following reasons: Invalid SAS2-SAS3 Transition; manually bypassed; exceeded loss of double word synchronization threshold; exceeded running disparity threshold; transmitter fault; exceeded CRC error threshold; exceeded invalid double word threshold; exceeded phy reset problem threshold; exceeded broadcast change threshold; or mirroring disabled on the other I/O module.

Corrective Action

If the Host phys were disabled because of an invalid transition, remove the SAS cable on the disabled phys completely from both IOMs and then recable correctly. Removing the cable completely allows both IOMs to reset. For other disabled host phy conditions, replace the shelf module to which the affected host phy belongs.

Syslog Message

Port %s on channels %s shelf ID %lld %s %s.

Parameters

phy (STRING): Host port that is being disabled.
channels (STRING): Channels that have the error if local, PARTNER for high-availability partner, UNUSED if unconnected.
shelfID (LONGINT): Shelf ID of the shelf reporting the error.
element (STRING): I/O module designator (A or B).
reason (STRING): Reason the host phy was disabled.

ds.sas.id.conflict.cleared

Severity

NOTICE

Description

This message occurs when a shelf ID conflict on a channel reported earlier is resolved.

Corrective Action

(None).

Syslog Message

Shelf ID conflict on channel %s (shelf ID: %lld, S/N: %s) was cleared.

Parameters

channel (STRING): Channel that the shelf is attached to.
shelfId (LONGINT): Shelf ID.
SerialNumber (STRING): Shelf serial number.

ds.sas.id.conflict.detected

Severity

ERROR

Description

This message occurs when a SAS shelf ID conflict is detected on a channel.

Corrective Action

Ensure that all of the disk shelves in a high-availability pair have a unique shelf ID. For instructions, see "Changing the disk shelf ID" in the Disk Shelf Installation and Service Guide for the shelf model.

Syslog Message

SAS shelf on channel %s (shelf ID: %lld, S/N: %s) reported a shelf ID conflict.

Parameters

channel (STRING): Channel that the shelf is attached to.
shelfId (LONGINT): Shelf ID.
SerialNumber (STRING): Shelf serial number.

ds.sas.multPhys.disableErr

Severity

ALERT

Description

This message occurs when the system detects that multiple Physical Layer Devices (PHYs) are disabled on a SAS disk shelf.

Corrective Action

Check whether the problems on the PHYs are valid by looking for PHY errors in nearby events. If multiple PHYs are disabled at the same time in a particular disk shelf module, replace the disk shelf module.

Syslog Message

Multiple phys have been disabled on the disk shelf %d on Channels %s, %s.
