Enclosures and Backplanes 143
Configuration This property displays the mode in which the enclosure is
operating. Possible values are:
Joined—Indicates that the enclosure is operating in joined-
bus mode.
Split—Indicates that the enclosure is operating in split-bus
mode.
Unified—Indicates that enclosure is operating in unified
mode.
Clustered—Indicates that the enclosure is operating in
cluster mode. Clustered mode is only available on cluster-
enabled RAID controllers. For more information, see
Background Initialization on PERC Controllers .
For more information on joined, split, and cluster modes, see
the enclosure hardware documentation. For information on
how to cable the enclosure to accommodate these different
modes, see the enclosure hardware documentation.
When toggling the bus configuration switch on a 220S or
221S enclosure, the enclosure should be powered off. For
more information, see
Changing the Mode on 220S and 221S
Enclosures .
Older 200S enclosures with a version 1.8 kernel that only have
one EMM may display Split Bus mode and not Joined Bus
mode. Joined Bus or Clustered when applicable are the only
possible modes in these circumstances.
Firmware Version This property displays the version of the enclosure firmware.
NOTE: For systems supporting multiple backplanes, the
firmware version appears as upstream and downstream
versions.
Service Tag This property displays the enclosure’s service tag number.
This number is required when talking to support. You can use
this number to identify a specific enclosure in your
environment by matching this number with the number on
the service tag affixed to the enclosure. For example, if you
have multiple enclosures and one of them experiences a
failure, you can use the service tag number to identify which
enclosure has failed.
