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 congured 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.
