Conversion of mode

An Active File Management (AFM) cache can be converted to another mode in some conditions to meet all types of requirements of data management by unlinking the fileset and by using mmchfileset -p afmmode command.

The mode conversion limitations are as follows:

A single-writer (SW) or independent-writer (IW) fileset with pending requests in the queue cannot be converted.
Local-update (LU) filesets cannot be converted to any other mode.
Before you convert a fileset from the IW mode to the SW mode, ensure that all the remaining IW filesets are converted to either RO or LU. This conversion is necessary to avoid home conflicts that are caused by writers from other IW filesets.
You cannot change the mode or disable AFM when the fileset is linked.
