This screen enables you to specify where to allocate capacity for the FlashCopy repository logical drive.
Select the corresponding radio button, and then select Next to continue the FlashCopy logical drive creation process by creating a new array.
Information: If the free capacity nodes in the Capacity Allocation list are grayed out, they are unusable. Either the array is degraded or there is a long running operation in progress, for example, modifying segment size, defragmentation or copyback.
You have three options:
Free capacity on the same array as the base logical drive (recommended)
Use this option to ensure that if drives associated with the array are moved to another storage subsystem, all logical drives associated with the FlashCopy logical drive reside on that group, and no further drives are required to be moved.
You are presented with a list of free capacity nodes on this array that are large enough for the FlashCopy repository logical drive, with their capacities and RAID levels.
Free capacity on different array
You should use this option if there isn't enough free capacity to create the FlashCopy repository logical drive on the same array where the base logical drive resides, or if that free capacity is unusable.
You are presented with a list of free capacity nodes that are large enough for the FlashCopy repository logical drive and that exist on arrays in the storage subsystem where the base logical drive does NOT reside. The capacity and RAID levels of the free capacity nodes are shown.
Unconfigured capacity to create a new array
Use this option if there is not enough free capacity to create the FlashCopy repository logical drive on the same array where the base logical drive resides, or there is not free capacity on another array. This option should also be used if free capacity on the same array where the base logical drive resides is unusable.
