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 degr
aded 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.
