Fields

Add these arrays to ranks

Indicates that the new arrays will be put into ranks (checked) or indicates that the new arrays will not be put into ranks (unchecked). If this box is checked, the Storage type field is required.

Storage type (Required if box above is checked)

The type of extent for which the rank is to be configured.

Note: Once you select either count key data (CKD) or fixed block (FB), the arrays are assigned.

The storage type can be set to one of the following values:

• Fixed block (FB) extents -- 1 GB. In fixed block architecture, the data (the logical volumes) are mapped over fixed-size blocks or sectors.
• Count key data (CKD) extents -- CKD Mod 1. In count-key-data architecture, the data field stores the user data.
