Cache Data Lost Error Message

Error Message: Cache data was lost, but the controller has recovered. This could be due to the fact that your controller had protected cache after an unexpected power loss and your system was without power longer than the battery backup time. Press any key to continue or 'C' to load the configuration utility.

Probable Cause: This message is displayed under the following conditions:

•The adapter detects that the cache in the controller cache has not yet been written to the disk subsystem.

•The controller detects an Error-Correcting Code (ECC) error while performing its cache checking routine during initialization.

•The controller discards the cache rather than sending it to the disk subsystem because the data integrity cannot be guaranteed.

Corrective Action: To resolve this issue, allow the battery to charge fully. If the problem persists, the battery or adapter DIMM might be faulty; contact Dell Technical Support.

Missing Disks in Virtual Disk Error Message

Error Message: The following virtual disks have missing

disks: (x). If you proceed (or load the configuration utility), these virtual disks will be marked OFFLINE and will be inaccessible. Please check your cables and ensure all disks are present. Press any key to continue, or 'C' to load the configuration utility.

Probable Cause: The message indicates that some configured disks were removed. If the disks were not removed, they are no longer accessible. The SAS cables for your system might be improperly connected.

Corrective Action: Check the cable connections and fix any issues. Restart the system. If there are no cable problems, press any key or <C> to continue.
