|
<div><p>When you vary on an independent ASP, several changes occur within
|
|
the "root" (/) file system.</p>
|
|
<div class="section"><p>These changes are:</p>
|
|
</div>
|
|
<div class="section"> <ul><li>A directory is created inside the /dev directory for the independent ASP.
|
|
The name of this directory matches the name of the device description associated
|
|
with the ASP. If this directory exists before the vary on request, and this
|
|
directory is not empty, then the vary on will proceed but you will not be
|
|
able to work with any UDFS's on the ASP. If this occurs, vary off the independent
|
|
ASP, either rename the directory or remove its contents and then try the vary
|
|
on request again.</li>
|
|
<li>Within the /dev/asp_name directory you will find the block special file
|
|
objects associated with all UDFS's that reside on the independent ASP. There
|
|
will always be a system-provided default UDFS. The path to the default UDFS's
|
|
block special file is: /dev/asp_name/QDEFAULT.UDFS</li>
|
|
<li>The default UDFS is mounted over the directory /asp_name. The /asp_name
|
|
directory does not need to exist before the vary on request. However, if
|
|
it does exist, it must be empty. If it is not empty, the ASP will still be
|
|
varied on, but the default UDFS will not be mounted. If this occurs, either
|
|
rename the directory or remove its contents and then either vary off and try
|
|
the vary on again or use the MOUNT command to mount the default UDFS.</li>
|
|
<li>If the independent ASP is either a primary or secondary ASP, and the default
|
|
UDFS was successfully mounted, then an additional file system will be mounted.
|
|
The independent ASP QSYS.LIB file system will be mounted over /asp_name/QSYS.LIB.
|
|
<div class="note"><span class="notetitle">Note:</span> This
|
|
file system cannot be mounted or unmounted independently of the default UDFS.
|
|
It will always be mounted or unmounted automatically.</div>
