Directory conversion considerations

Here are several things to consider during the directory conversion process.

Conversion status determination
Shortly after IBM i V5R3M0 operating system or a later release is installed, the conversion to *TYPE2 directories will automatically begin for any of the file systems which have not yet been converted to support *TYPE2 directories. This conversion processing will take place in a secondary thread of the QFILESYS1 system job.
User profiles creation
The conversion function creates a user profile that is used while the conversion function is running. This user profile has the name QP0FCWA. It is used by the conversion function to own converted directories in the file system if the original owner is unable to own their directories.
Objects renamed
*TYPE2 directories require the link names to be valid UTF-16 names.
User profile considerations
While the conversion is running, every attempt is made to ensure that the same user profile that owns any *TYPE1 directories continues to own the corresponding *TYPE2 directories.
Auxiliary storage requirements
Auxiliary storage requirements should be considered while the system is converting the directories in a file system to the *TYPE2 format.
Tips: Symbolic link
Symbolic links are objects within the integrated file system that contain a path to another object.
Tips: Independent ASP
If the user-defined file systems in an independent ASP have not yet been converted to the *TYPE2 directory format, they will be converted the first time the independent ASP is varied on to a system installed with V5R2 or later of the operating system.
Tips: Saving and restoring
Directories that exist as *TYPE1 can be saved and restored in a file system that has been converted to *TYPE2.
Tips: Reclaiming integrated file system objects
While the system is converting the "root" (/), QOpenSys and user ASP UDFS file systems to support the *TYPE2 directory format, the Reclaim Storage (RCLSTG) and Reclaim Object Links (RCLLNK) commands cannot be run on any integrated file system directories including those in independent ASPs.
Integrated file system scanning
Objects in the "root" (/), QOpenSys and user ASP UDFS file systems will not be scanned using the integrated file system scan-related exit points until the file systems have fully converted to the *TYPE2 directory format.
