*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.
Number of Processes That Can Be Executed Simultaneously
The following upper limits are applied to the number of processes that are to be executed.
• Only one process can be executed with Logical Device Expansion (LDE). Two or more processes cannot be
executed simultaneously in the same ETERNUS AF.
•
A total of 32 processes can be executed simultaneously for TPV balancing, FTRP balancing, RAID Migration,
Flexible Tier Migration, and Non-disruptive Storage Migration.
Capacity That Can Be Processed Simultaneously
The following upper limit is applied to the capacity of processes that are to be executed.
• A total capacity of 128TB can be processed simultaneously for TPV balancing, FTRP balancing, RAID Migration,
Flexible Tier Migration, and Non-disruptive Storage Migration.
