Battery Discharged or Disconnected Error Message

Error Message: The battery is currently discharged or disconnected. Verify the connection and allow 30 minutes for charging.If the battery is properly connected and it has not returned to operational state after 30 minutes of charging then contact technical support for additional assistance.

Probable Cause: This message may appear for controller without battery, depending on the virtual disks’ policies.

Corrective Action:

•The controller battery is missing or currently inaccessible, contact Dell support if the problem persist after 30 minutes.

•The controller battery is completely discharged and needs to be charged for it to become active. You must first charge the battery, then wait for a few minutes for the system to detect it.

Degraded State of Virtual Disks

A redundant virtual disk is in a degraded state when one or more physical disks have failed or are inaccessible. For example, if a RAID 1 virtual disk consists of two physical disks and one of them fails or become inaccessible, the virtual disk become degraded.

To recover a virtual disk from a degraded state, you must replace the failed physical disk and rebuild it. Once the rebuilding process is complete, the virtual disk state changes from degraded to optimal. For information on rebuilding the disk, see "Performing a Manual Rebuild of an Individual Physical Disk" on page 85.

Memory Errors

Memory errors can corrupt cached data, so the controllers are designed to detect and attempt to recover from the memory errors. Single-bit memory errors can be handled by the controller and do not disrupt normal operation. A notification is sent if the number of single-bit errors exceeds a threshold value.
