This section will cover the RAID Concept in general.
RAID Set
A RAID set is a group of disks connected to a RAID controller. A RAID set contains one or more volume sets. The
RAID set itself does not define the RAID level (0, 1, 1E, 3, 5, 6, 10, 30, 50 60, etc); the RAID level is defined within
each volume set. Therefore, volume sets are contained within RAID sets and RAID Level is defined within the volume
set. If physical disks of different capacities are grouped together in a RAID set, then the capacity of the smallest disk
will become the effective capacity of all the disks in the RAID set.
Volume Set
Each volume set is seen by the host system as a single logical device (in other words, a single large virtual hard disk).
A volume set will use a specific RAID level, which will require one or more physical disks (depending on the RAID
level used). RAID level refers to the level of performance and data protection of a volume set. The capacity of a

Check DRAM
Check the DRAM module and replace with new
one if required.
Check air flow and cooling fan of the enclosure,
and contact us.
Check air flow and cooling fan of theenclosure.
Check cooling fan of the enclosure and replace
with a new one if required.
Check disk information to find out which
channel missing.
