|
|
the action to take when the available storage in the system disk pool (also
|
|
known as auxiliary storage pool) has reached the maximum specified for Maximum
|
|
system disk pool usage.</p>
|
|
<p>You may specify any of the following actions:</p>
|
|
<ul><li><span class="uicontrol">Send message to system operator and system message queue (*MSG)</span> <p>Message
|

CPI099C is sent to the system message and system operator queues. This message

is already in the restricted state.</p>

<p>you cannot start a subsystem until:</p>

still at the maximum level.</p>
