|
<div><p>Understand how to schedule moves of memory, processors, interactive
|
||
|
|
performance, and I/O processors.</p>
|
||
|
|
<div class="section"><p>You can schedule the movement of memory, processors, interactive
|
||
|
|
performance, and I/O processors. You have the option of choosing to perform
|
||
|
|
a task immediately or choosing a later time. Using the logical partition scheduling
|
||
|
|
functions, gives you the flexibility to accommodate changing workloads and
|
||
|
|
demands on resources.</p>
|
||
|
|
<p>You need to meet Dedicated Service Tools (DST)
|
||
|
|
and <span class="keyword">i5/OS™</span> security requirements
|
||
|
|
before scheduled LPAR moves will work successfully.</p>
|
||
|
|
<p>The primary partition
|
||
|
|
for the system where the resource move will occur must have the DST password
|
||
|
|
level set to use password support. To change the DST password level, follow
|
||
|
|
these steps:</p>
|
||
|
|
</div>
|
||
|
|
<ol><li><span>From DST, select option 5 (Work with DST environment).</span></li>
|
||
|
|
<li><span>Select option 6 (Service tools security data).</span></li>
|
||
|
|
<li><span>Select option 6 (Password level).</span></li>
|
||
|
|
<li><span>Press Enter to confirm the password level change.</span></li>
|
||
|
|
</ol>
|
||
|
|
<div class="section"><p>The DST user ID password must be changed AFTER the DST password
|
||
|
|
level is set to apply the new encryption level to the DST user ID. This ID
|
||
|
|
is the uppercase equivalent of the same user profile. For example, OS/400user/password=
|
||
|
|
'BOB'/'mypass' needs DST user='BOB'/'MYPASS'. The DST user profile needs the
|
||
|
|
following authority:</p>
|
||
|
|
<ol><li>System Partitions - Operations <p>or</p>
|
||
|
|
</li>
|
||
|
|
<li>System Partitions - Administration</li>
|
||
|
|
</ol>
|
||
|
|
<p>User profile needs the following special authorities:</p>
|
||
|
|
<ol><li>*ALLOBJ - All object authority</li>
|
||
|
|
<li>*SERVICE - Service</li>
|
||
|
|
</ol>
|
||
|
|
<p>A user profile must exist on the central system and the system where
|
||
|
|
the resource move will occur. By default, Management Central requires the
|
||
|
|
user profile used to sign on to the central system to have the same password
|
||
|
|
on each endpoint system. For more information, see the iSeries™ Navigator help for the "Require
|
||
|
|
password on endpoint systems" field on the Security tab in Management Central
|
||
|
|
properties.</p>
|
||
|
|
<p>LPAR resource moves are scheduled and run with the user
|
||
|
|
profile used to access the central system.</p>
|
||
|
|
<p>The <a href="../rzamh/rzamhwhatsts.htm">service
|
||
|

<ol><li>From a command line, type ADDSRVTBLE (Add Service Table Entry) and press
