Preserved Cache State

Multi-bit errors are more serious as they result in corrupted data and data loss. The following are the actions that occur in the case of multi-bit errors:

•If a multi-bit error occurs while accessing data in the cache when the controller is started with dirty cache, the controller discards the cache contents. The controller generates a warning message to the system console to indicate that the cache was discarded and generates an event.

•If a multi-bit error occurs at run-time either in code/data or in the cache, the controller stops.

•The controller logs an event to the controller’s internal event log and a message during POST is displayed indicating a multi-bit error has occurred.

NOTE: In case of a multi-bit error, contact Dell Technical Support.

Preserved Cache State

The controller preserves the dirty cache from a virtual disk if the virtual 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.

Use the BIOS Configuration Utility (<Ctrl><R>) utility to select whether to import the virtual disk or discard the preserved cache. In the VD Mgmt menu, select Manage Preserved Cache and follow the steps on the screen.
