Auto Configure RAID0 Operation
Does my controller support this feature? See Supported Features.
You can use this feature to automatically configure all physical disks in Ready state into RAID 0 virtual disks. This feature is supported on
PERC 9 and later family of hardware controllers with the latest firmware version.
NOTE:
When performing an Auto Configure RAID0 operation on a single storage controller, the maximum number of
physical disks supported is 192. Only physical disks in Ready state are configured into RAID 0 virtual disks.
Before you proceed, browse to the physical disks details page and verify if the physical disks are in Ready state. To configure physical
disks into RAID 0 virtual disks, perform the following steps:
1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
2. Select the Controller object.
3. Click Information/Configuration on the controller Properties page.
4. In the Controller Tasks drop-down menu, select Auto Configure RAID0, and then click Execute.
The Auto Configure RAID0 window is displayed. Read the messages displayed on this window before you proceed.
5. Click Confirm to configure the physical disks.
The auto configure operation may take time to complete, depending on the configuration and available physical disks in Ready state.
The Auto Configure RAID0 operation is successful, only if the Alert Log is updated. You can check the Alert Log for more
information.
NOTE:
If there are no physical disks in Ready state and you repeat the procedure, the Auto Configure RAID0 operation
automatically ignores your request without displaying any error message. For more information about alerts and their
corrective actions, see the Server Administrator Messages Reference Guide . at dell.com/openmanagemanuals.
System Configuration Lock Down Mode
‘System Configuration Lock Down Mode’ provide a configurable option to the customer so that after it is enabled, any configuration on
that particular system is not permitted with some exceptions. Typical usage of this setting is after the system is provisioned to a certain
level along with the rest of the systems in the domain then enabling this mode reduces the drift the systems usually see during the
operation over a period of time.
When the server is in “System configuration lock down” mode you will not be allowed to initiate any of the configuration operation from
either OMSS GUI or CLI. If this mode is set, you are not allowed to perform most of the operations in OMSS except some of the
enumeration or reporting operations.
You can enable the lock down mode from the iDRAC GUI. For enabling the lock down mode, you have to select the Turn on the System
Lockdown mode option from the More Actions drop-down menu on the iDRAC page. It may take some time for the changes to be
available on the OMSS GUI.
NOTE:
OMSS does not support configuring or setting the lock down mode from either GUI or CLI. For enabling the
system configuration lock down mode, you have to access iDRAC GUI or similar applications.
