Enclosure and Backplane Properties

Table 1. Enclosure and Backplane Properties
Property Definition
ID It displays the ID of the enclosure or backplane.
Status These icons represent the severity or health of the storage component. For more information, see Storage Component Severity.
  • NormalNormal/OK
  • WarningWarning/Non-critical
  • CriticalCritical/Failure/Error
NOTE: If the enclosure is connected to the controller in redundant path mode (for more information, see Setting the Redundant Path Configuration), the loss of connection to any one EMM may cause the enclosure status to be displayed as degraded.
Name It displays the name of the enclosure or backplane.
State It displays the status of the enclosure or backplane. Possible values are:
  • Ready—The enclosure or backplane is functioning normally.
  • Degraded—The enclosure has encountered a failure and is operating in a degraded state. This state does not apply to backplanes.
  • Failed—The enclosure or backplane has encountered a failure and is no longer functioning.
Connector It displays the number of SAS port connectors that are attached to the enclosures or backplanes. This number matches the number connector on the controller hardware. On PERC 10 and later internal controllers, only one logical connector is displayed.
Enclosure ID It displays the enclosure ID assigned to the enclosure by Storage Management. Storage Management numbers the enclosures attached to the controller starting with zero. This number is the same as the enclosure ID number reported by the omreport command. For information about Command-Line Interface, see the Server Administrator Command Line Interface User’s Guide.
Target ID It displays the enclosure to which the controller connector is attached. The default value is six.
Configuration It displays the mode in which the enclosure is operating. Possible values are:
  • Joined—Indicates that the enclosure is operating in the joined-bus mode.
  • Split—Indicates that the enclosure is operating in the split-bus mode.
  • Unified—Indicates that the enclosure is operating in the 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 about joined, split, and cluster modes, see the enclosure hardware documentation. For information about how to cable the enclosure to accommodate these different modes, see the enclosure hardware documentation. The bus configuration switch when toggled on a 220S or 221S enclosure, the enclosure should be turned 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 modes may display when applicable in these circumstances.
Firmware Version It displays the version of the enclosure firmware.
NOTE: For systems supporting multiple backplanes, the firmware version appears as upstream and downstream versions.
Service Tag It displays the enclosure Service Tag. The enclosure is identified by a unique Service Tag number. This information is used to route support calls to the appropriate personnel.
Express Service Code The enclosure is identified by a unique Express Service Code number. This information is used to route support calls to the appropriate personnel.
Asset Tag It displays the asset tag information for the enclosure. You can change this property using the Setting Asset Data task.
Asset Name It displays the name that is assigned to the enclosure. You can change this property using the Setting Asset Data task.
Backplane Part Number It displays the part number of the enclosure backplane.
SAS Address It displays the SAS address of the SAS backplane.
Split Bus Part Number It displays the part number of the enclosure split-bus module. A split-bus is indicated by a single triangle symbol on the back of the enclosure.
Enclosure Part Number It displays the part number of the enclosure.
Enclosure Alarm It displays whether the alarm on the enclosure is enabled or disabled.
