    T10 DIF volumes can be used by any type of Open host with the exception of iSeries, but active protection is supported only for Linux on IBM Z or AIX on ™ IBM Power Systems . The protection can only be active if the host server has T10 DIF enabled.

  • Page 43: Lun Calculation

    If you migrate an existing non-striped volume to the same extent pool with a rotate extents allocation method, then the volume is "reorganized." If you add more ranks to an existing extent pool, then the "reorganizing" existing striped volumes spreads them across both existing and new ranks. You can configure and manage storage pool striping using the DS Storage Manager, and DS CLI, and DS Open API.

    On open volumes with 520 byte blocks, you can select one of the supported LUN sizes that are used on IBM i processors to create a LUN. The operating system uses 8 of the bytes in each block. This leaves 512 bytes per block for your data. Variable volume sizes are also supported.

  • Page 87: Chapter 5. Planning Use Of Licensed Functions

    Each licensed function indicator requires a corequisite 283x or 904x function authorization. Function authorization establishes the extent of IBM authorization for the licensed function before the feature activation code is provided by IBM. Each function authorization applies only to the specific storage system (by serial number) for which it was acquired.

  • Page 88: Ordering Licensed Functions

    You do not specify the license scope when you order function authorization feature numbers. Feature numbers establish only the extent of the IBM authorization (in terms of physical capacity), regardless of the storage type. However, if a licensed function has multiple license scope options, you must select a license scope when you initially retrieve the feature activation codes for your storage system.
