NOTE: If the Controllers are in fault-tolerant mode, then the following information regarding the fault-tolerant status and
mode is also displayed:
• Fault Tolerant Mode – Shared, Active/Passive
• Fault Tolerant Status – Healthy/Normal, or Lost/Degraded
• Peer Controller - Indicates the name of controller that acts as the peer (stand-by) in case of a fault-tolerant mode supported
by two controllers
NOTE: If the peer controller is disabled, the name is displayed as Disabled PERC (Integrated 2) or Disabled PERC(SPERC
Slot 6) and the Status is displayed as Unknown, which implies that the peer controller is turned o.

Importing or Clearing Foreign Conguration
A foreign disk must be inserted into the chassis.
To import or clear the foreign conguration:
1 In the left pane, click Chassis Overview > Storage > Controllers > Setup.
2 On the Controller Setup page, in the Foreign Conguration section, for the respective controller, click:
• Clear Foreign Conguration to clear the existing conguration of the disk.
• Import/Recover to import the disk with the foreign conguration.
NOTE
: When you remove the disks of a particular virtual disk, reset the controller and reinsert the drives one by one,
multiple virtual disk instances of dierent sizes and states are displayed on the Foreign Conguration page. The correct
state and size of the virtual disk is displayed after the import activity is complete.
Conguring Storage Controller Settings
You can modify existing properties of a storage controller or congure the properties of a newly-installed storage controller.
Conguring Storage Controller Settings Using CMC Web
Interface
Make sure at least one storage controller is installed in the chassis.
Tocongure the storage controller settings:
1 In the CMC Web interface, go to Chassis Overview > Storage > Controllers > Setup.
2 On the Controller Setup page, from the Controller drop-down menu, select the controller.
NOTE
: Note the following:
• If the storage controllers are in fault-tolerant mode, and if both have the same rmware version, then both the controllers are
displayed as a single device in the drop-down menu. For example, Shared PERC8 (Integrated 1) or Shared PERC8 (Integrated
2) or Shared PERC8 (SPERC Slot 5) or Shared PERC8 (SPERC Slot 6). If the settings of two controllers are dierent, the
Settings Incompatible message is displayed. You can set the properties of fault-tolerant controllers so that the properties are
same on both the controllers. Controllers in this mode cannot have separate properties.
• If a second storage controller with a dierent rmware version is installed, then the controllers are displayed as two dierent
components in the drop-down menu. For example, Shared PERC8 (Integrated 1), Shared PERC8 (Integrated 2), Shared
PERC8 (SPERC Slot 5) and Shared PERC8 (SPERC Slot 6).
