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.
• 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.
Replace the RAID controller in the DR Series system.
Reinsert or replace the RAID controller in the DR Series
system.

• Check the SAS cable connections between the

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.
This disk type is unsupported and cannot be used in this
configuration.
Replace the unsupported physical disk with a Dell-
supported SAS physical disk.
Remove the physical disk and reinsert it (the drive is non-
operational 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.
