<div><p><span>(This information applies only if you are upgrading
|
|
from V5R2. The conversion does not affect the length of time for an upgrade.)</span> As
|
|
of V5R1, the "root" (/), QOpenSys, and user-defined file systems (UDFS) in
|
|
the integrated file system support the *TYPE2 directory format. </p>
|
|
<p>The *TYPE2 directory format is an enhancement of the original *TYPE1 directory
|
|
format. *TYPE2 directories have a different internal structure
|
|
than *TYPE1 directories and provide improved performance and reliability.
|
|
In releases V5R1 and V5R2, you could optionally convert to the *TYPE2 directory
|
|
format using the appropriate conversion utility. Additionally, if the server
|
|
was preloaded with V5R2, the directory format was *TYPE2.</p>
|
|
<p>If you have not previously converted to support *TYPE2 directories,
|
|
the conversion to *TYPE2 directories automatically begins for any of the file
|
|
systems shortly after <span>V5R4</span> is installed. This conversion
|
|
runs in the background during normal operations and should not significantly
|
|
impact your system activity. For more information on integrated file system
|
|
directory conversions, see <a href="../ifs/rzaaxconchapter.htm">Convert directories from *TYPE1 to *TYPE2</a> .</p>
