<h1 class="topictitle1">Change the IPL source for a logical partition</h1>
<div><p>You can choose a separate initial program load (IPL) source (type)
for each logical partition.</p>
<p>Each IPL source (A, B, C, or D) on a system with logical partitions works
just like it would on a system without logical partitions.</p>
<p>For information on how each IPL source works and why you may need to change
it, refer to <a href="../rzal2/rzal2ipltypeco.htm" target="_blank">IPL
Type</a> for more information.</p>
<div class="attention"><span class="attentiontitle">Attention:</span> Only a hardware service representative should use IPL
source C. Only use IPL source C under the direction of your service representative.
Severe data loss can occur with improper use of this function.</div>
<p>To change the IPL source for a partition, you should be working with the
remote control panel. You need a Service Tools user ID with operations or
administration authority to the System Partitions function in Dedicated Service
Tools (DST) to work with the remote control panel.</p>
<p>Refer to <a href="../rzatm/rzatmcpnlfunct.htm" target="_blank">Control
panel functions</a> for information on how to use the remote control panel
and <a href="../rzal2/rzal2chgmodetype.htm" target="_blank">Change
operating modes and IPL types</a> for instructions on how to change the
IPL source for a partition.</p>
