6 Select OK. Firmware or Physical disks out-of-date Issue:The Firmware or Drives out of date adn results in unknown disk errors. Solution: • Update the Firmware/ PERC Controller. Cannot boot to Windows due to foreign configuration About this task When a foreign configuration exists in the controller, and you cannot boot to Windows, do the following: Steps 1 Import the foreign configuration to the RAID controller. See, Importing foreign configuration using PERC. 2 Rebuild the failed hard drives. See, Rebuild. 3 Upgrade the iDRAC firmware/PERC. See, Downloading drivers and firmware. Offline or missing virtual drives with preserved cache error message Error Message: There are offline or missing virtual drives with preserved cache. Please check the cables and ensure that all drives are present. Press any key to enter the configuration utility. Probable Cause: The controller preserves the dirty cache from a virtual disk if the disk becomes offline or is deleted because of missing physical disks. This preserved dirty cache is called pinned cache, and is preserved until you import the virtual disk, or discard the cache. Corrective Action: Use the utility to import the virtual disk or discard the preserved cache. For the steps used to manage preserved cache, see Managing preserved cache. NOTE: Ctrl R is not available for systems set to UEFI boot mode. Use the HII menu to manage preserved cache in these cases. Managing preserved cache About this task If a virtual disk goes offline or is deleted because of missing physical disks, the controller preserves the dirty cache from the virtual disk. The preserved dirty cache, known as pinned cache, is preserved until you import the virtual disk or discard the cache. NOTE: Certain operations, such as creating a new virtual disk, cannot be performed if preserved cache exists. You have to enter the BIOS Configuration Utility ( ) to resolve the situation before you boot to the operating system. Messages are displayed notifying you that you must enter the BIOS Configuration Utility ( ) to discard the preserved cache or import the virtual disks with the preserved cache. CAUTION: If there are any foreign configurations, it is strongly advised that you import the foreign configuration before you discard the preserved cache. Otherwise, you might lose data that belongs with the foreign configuration. Troubleshooting hardware issues 57

Offline
or missing virtual drives with preserved cache error
message
Error Message:
There are offline or missing virtual drives with preserved cache. Please check the cables and
ensure that all drives are present. Press any key to enter the configuration utility.
Probable Cause:
The controller preserves the dirty cache from a virtual disk if the disk becomes
offline
or is deleted because of missing physical disks. This
preserved dirty cache is called pinned cache, and is preserved until you import the virtual disk, or discard the cache.
Corrective Action:
Use the <Ctrl> <R> utility to import the virtual disk or discard the preserved cache. For the steps used to manage preserved cache, see

NOTE:
Ctrl R is not available for systems set to UEFI boot mode. Use the HII menu to manage preserved cache in these cases.
Managing preserved cache
About this task
If a virtual disk goes
offline
or is deleted because of missing physical disks, the controller preserves the dirty cache from the virtual disk. The
preserved dirty cache, known as pinned cache, is preserved until you import the virtual disk or discard the cache.
NOTE:
Certain operations, such as creating a new virtual disk, cannot be performed if preserved cache exists. You have to enter
the BIOS
Configuration
Utility (<Ctrl> <R>) to resolve the situation before you boot to the operating system. Messages are
displayed notifying you that you must enter the BIOS
Configuration
Utility (<Ctrl> <R>) to discard the preserved cache or
import the virtual disks with the preserved cache.
CAUTION:
If there are any foreign
configurations,
it is strongly advised that you import the foreign
configuration
before you
discard the preserved cache. Otherwise, you might lose data that belongs with the foreign
configuration.
