Alert Message Temperature probes have recorded temperatures in the failed range. Description/Meaning or Action • Check the Events page in the DR Series system for specific temperature events and the location of the temperature probes. • Check the data center air conditioning, ventilation, and internal system cooling fans for any problems. • Ensure there is proper air flow through the storage appliance, and as needed, clean the cooling vents. Voltage probes have recorded readings in the failed range. • Check the Events page in the DR Series system for specific voltage events and the location of the voltage probes. • Check the power supplies. If there are no issues with the power supplies, have a service technician check the DR Series system appliance to see if it requires any servicing. Storage Controller failed. Replace the RAID controller in the DR Series system. Storage Controller is missing. Reinsert or replace the RAID controller in the DR Series system. Storage Controller has an illegal configuration. The expected number of virtual drives is , and the actual number of virtual drives found was . Run the Dell Restore Manager (RM) utility to repair the drive configuration mismatch. The expected number of enclosures is , and the actual number of enclosures found was . • Check the SAS cable connections between the storage controller and all its enclosures. • Check the power cable connections to the enclosure power supplies. Physical disk failed. Physical disk is missing, removed, or it cannot be detected. Physical disk predictive failure reported. Replace the physical disk that failed. Reinsert or replace the physical disk. Replace the physical disk. NOTE: Even though the disk may not have failed yet, the recommended best practice is to replace the disk. Physical disk is an unsupported type. Physical disk has been manually set to offline with a configuration command. Physical disk is foreign. This disk type is unsupported and cannot be used in this configuration. Replace the unsupported physical disk with a Dellsupported SAS physical disk. Remove the physical disk and reinsert it (the drive is nonoperational in this state). This can occur when a storage controller has been replaced or all drives have been migrated from another system. In such cases, the foreign configuration should be imported. 153

Even though the disk may not have failed yet,
the recommended best practice is to replace the disk.
Physical disk <
number
> is an unsupported type.
This disk type is unsupported and cannot be used in this
configuration.
