Property Denition

State Displays the current state of the EMMs. Possible values are:

• Ready — EMM is functioning normally.

• Degraded — EMM has encountered a failure and is operating in a

degraded state.

• Failed — EMM has encountered a failure and is no longer

functioning. Storage Management is unable to communicate with the

enclosure using SES commands. The Failed state is displayed when

the enclosure does not respond to a status query from Storage

Management. For example, disconnecting the cable.

• Missing — EMM is not present in the enclosure.

• Not Installed — EMM is not present in the enclosure.

Part Number Displays the part number of the EMM module.

Type Indicates whether the EMM is a SCSI SES Module or a SCSI

Terminator.

SCSI SES Module — A SCSI SES module provides SCSI Enclosure

Services (SES) and SCSI Accessed Fault-Tolerant Enclosures (SAFTE)

reporting to the host server, control of all system LED indicators, and

monitoring of all environmental elements, such as temperature sensors,

cooling modules, and power supplies.

SCSI Terminator — The SCSI terminator card is only used if the 220S

or 221S enclosure is not congured with a redundant SCSI SES module

type of EMM. In systems equipped with two SCSI SES modules, the

SCSI termination is done through the EMMs.

Firmware Version Indicates the version of the rmware loaded on the EMM. All EMM

modules in the enclosure should have the same level of rmware.

NOTE: For multiple backplanes, the rmware version appears as

upstream and downstream versions.

SCSI Rate Displays the maximum SCSI speed that the EMM in a SCSI enclosure

supports.

Enclosure And Backplane Health

Displays the status of the enclosure or backplane and the components attached to the enclosure or backplane.
