<div><p><span>The "root" (/), QOpenSys, and user-defined
|
||
|
|
file systems (UDFS) in the integrated file system support the *TYPE2 directory
|
||
|
|
format as of OS/400<sup>®</sup> V5R1.</span></p>
|
||
|
|
<p>The *TYPE2 directory format is an enhancement of the original *TYPE1 directory
|
||
|
|
format. *TYPE2 directories have a different internal structure from *TYPE1
|
||
|
|
directories and provide improved performance and reliability. In addition
|
||
|
|
to improved performance and reliability, new functions such as integrated
|
||
|
|
file system scanning support are only available for objects in *TYPE2 directories.
|
||
|
|
See <a href="rzaaxscan.htm#rzaaxscan">Scanning support</a> for more information.</p>
|
||
|
|
<p>Shortly after <span class="keyword">i5/OS™</span> 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 should
|
||
|
|
not significantly impact your system activity as it will run in a low priority
|
||
|
|
background job. </p>
|
||
|
|
<p>If the conversion function has not yet completed, and the system has a
|
||
|
|
normal or abnormal IPL, the conversion function will resume when the IPL is
|
||
|
|
completed. The conversion will restart on every IPL until all eligible file
|
||
|
|
systems have been fully converted.</p>
|
||
|
|
<p>The file systems that are eligible for this automatic conversion are "root"
|
||
|
|
(/), QOpenSys and the user-defined file systems for ASPs 1 through 32. </p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> You can avoid the automatic conversion to *TYPE2

directories if you convert the file systems before installing V5R3M0 operating
