both data cache and accessed physical disks.
WB
Write-Back cache-write policy. A caching technique in which the
completion of a write request is signaled as soon as the data is
in cache and actual writing to non-volatile media occurs at a
later time. It speeds up system write performance but needs to
bear the risk where data may be inconsistent between data
cache and the physical disks in one short time interval.
RO
Set the volume to be Read-Only.
DS
Dedicated Spare disks. The spare disks are only used by one
specific RG. Others could not use these dedicated spare disks for
any rebuilding purpose.
GS
Global Spare disks. GS is shared for rebuilding purpose. If some
RGs need to use the global spare disks for rebuilding, they could
get the spare disks out from the common spare disks pool for
such requirement.
DG
DeGraded mode. Not all of the array’s member disks are
functioning, but the array is able to respond to application read
and write requests to its virtual disks.
