ยก: Possible, ยด: Not possible
*1 : This indicates that the copy session is being set or the copy session is already set.
*2 : This indicates the copy session setting operation.
*3 : Volume formatting will cause losing the entire data in volumes.
*4 : The function cannot be executed when the same volume is set as the execution target.
*5 : LUN concatenated volumes can be set as the RAID Migration source.
Note that LUN concatenated volumes cannot be set as the RAID Migration destination.
*6 : RAID Migration that expands the capacity cannot be performed on any volumes with copy sessions in LUN units.
*7 : The function cannot be executed when the same RAID group is set as the execution target.
*8 : When a copy session with a copy area that is specified in LUN units exists, volume capacity expansion cannot be performed because
copying cannot be processed for the expanded part. When a copy session is specified for a logical disk, volume capacity expansion can
be performed.
*9 : Copy sessions in LUN units cannot be performed on a volume that is being expanded with RAID Migration.
*10: Complies with Advanced Copy specifications (multi-copy/Cascade Copy).
*11: The REC session needs to be suspended or stopped before the operation.
*12: The motor-off state of Eco-mode is stopped, and the drive motor is activated (spin-up).
*13: EC/REC can be performed (the motor-off state of Eco-mode will be stopped).
OPC/QuickOPC/SnapOPC/SnapOPC+ cannot be performed (the
ETERNUS DX returns an error).
