Storage Health
The Storage Dashboard displays the combined status for each controller and lower-level storage components. For example, if the health
of the storage system has been compromised due to a degraded enclosure, both the enclosure Health and the controller severity on the
Storage Dashboard display a yellow exclamation mark to indicate a Warning severity. If a controller on the Storage Dashboard displays
a Warning or Critical status, perform the following actions to investigate the cause:
• Click Check Alert Log to display the Alerts Log. Review the Alert Log for alerts relating to the status of the controller and its lower-
level components. The Check Alert Log link is only displayed when the controller displays a Warning or Critical status.
• Select the controller and investigate the status of the lower-level components. For more information, see the Storage Component
Severity section.
• Click the virtual disk that is in degraded state to display the Physical Disk Properties page.
NOTE: The virtual disk link is displayed only if the physical disks that are part of the virtual disk, are in a Warning or
Critical state.
For more information on how the status of lower-level components is rolled up into the status displayed for the controller, see the
Determining The Health Status For Storage Components section.
How do I configure RAID using operating system
deployment wizard
You can configure RAID using an operating System deployment wizard on the Dell Lifecycle controller. To configure RAID:
• Launch the Lifecycle Controller.
• In the left pane, click OS Deployment.
• On the OS Deployment page, click Deploy OS.
• On the Deploy OS page, click Configure RAID First, and then click Next.
• The storage controllers available for configuration are displayed in the RAID Configuration page.
NOTE: Make sure that the selected controller is not in a non-RAID mode.
• Select a storage controller. The RAID configuration options are displayed.
• Follow the instruction on the screen, complete the RAID setting tasks, and then click Finish.
The RAID configuration is applied to the virtual disks.
To create virtual disks using RAID configuration at the preferred RAID level, watch the Dell Lifecycle Controller RAID configuration video
on YouTube https://www.youtube.com/watch?v=JFPmeHNENV4
Foreign drivers on physical disk
Importing Foreign Configurations
NOTE:
To make the foreign configuration effective, ensure that you have installed the latest version of Server
Administrator. For more information, see the Dell EMC OpenManage Software Support Matrix available on the support
site.
You can import a foreign configuration only if it contains a virtual disk that is either in a Ready or Degraded state. In other words, all of the
virtual disk data must be present, but if the virtual disk is using a redundant RAID level, the additional redundant data is not required.
For example, if the foreign configuration contains only one side of a mirror in a RAID 1 virtual disk, then the virtual disk is in a Degraded
state and can be imported. On the other hand, if the foreign configuration contains only one physical disk that was originally configured as
a RAID 5 using three physical disks, then the RAID 5 virtual disk is in a Failed state and cannot be imported.
In addition to virtual disks, a foreign configuration may consist of a physical disk that was assigned as a hot spare on one controller and
then moved to another controller. The Import Foreign Configuration task imports the new physical disk as a hot spare. If the physical disk
was set as a dedicated hot spare on the previous controller, but the virtual disk to which the hot spare was assigned is no longer present
in the foreign configuration, then the physical disk is imported as a global hot spare.
