Users Guide

The firmware for the EMM must be at the same level as that of the enclosure. The status of the EMMs is displayed as degraded if there is
a mismatch between the EMM firmware.
To verify the EMM firmware version:
1. In the Server Administrator window, under the system tree, click Storage dashboard.
2. Expand the tree view until the EMMs object is displayed.
3. Select the EMMs object. The firmware version for each EMM is displayed in the Firmware Version column in the right pane.
For information related to the enclosure’s EMMs, see Enclosure Management Modules (EMMs).

Property Definition
Status These icons represent the severity or health of the storage component.
— Normal/OK
— Warning/Non-critical
— Critical/Failure/Error
— Unknown
For more information, see Storage Component Severity.
Name Displays the name of the EMM.
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 configured 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 firmware loaded on the EMM. All EMM modules
in the enclosure should have the same level of firmware.
NOTE: For multiple backplanes, the firmware version appears as
upstream and downstream versions.
SCSI Rate Displays the maximum SCSI speed that the EMM in a SCSI enclosure
supports.
