<p>The Start DASD Management Operation (QYASSDMO) API performs various disk
|
|
management operations as indicated by the Operation key input parameter.</p>
|
|
|
|
<p>A session handle must be obtained prior to using this API by starting a disk
|
|
management session using the Start DASD Management Session (QYASSDMS) API.
|
|
Subsequent QYASSDMS API calls pass this session handle as an input
|
|
parameter.</p>
|
|
|
|
<p>Disk management operations that can be requested are:</p>
|
|
|
|
<ul>
|
|
<li>Change the storage threshold percentage of an ASP</li>
|
|
|
|
<li>Add disk units to an ASP</li>

<li>Suspend mirrored protection on a disk unit</li>
|
|
|
|
<li>Resume mirrored protection on a disk unit</li>
|
|
|
|
<li>Include a disk unit in device parity protection</li>
|
|
|
|
<li>Rebuild data on a disk unit after a device parity fault</li>
|
|

|
|
<p>Most operations require that an operation variable be specified. There are
|
|
various operation formats associated with the operation that need to be placed
|
|
in the operation variable. When an operation variable is required, the input
|
|
parameters Length of operation variable and Format name of operation variable
|
|
also need to be specified. If the operation does not need an operation variable
|
|
to be supplied, then enter a value of zero in the Length of operation variable
|
|
parameter and enter a value of all blanks for Format name of operation
|
|
variable. When the parameter Length of operation variable is set to zero and
|
|
the parameter Format name of operation variable is all blanks, the parameter
|
|
operation variable is ignored.</p>

<h3>Authorities and Locks</h3>
|
|
|
|
<p>To use this API you must have *SERVICE special authority or be authorized to
|
|
the Service Disk Units function of Operating System/400 through iSeries
|
|
Navigator's Application Administration support. The Change Function Usage
|
|
Information (QSYCHFUI) API, with a function ID of QIBM_QYAS_SERVICE_DISKMGMT,
|
|
also can be used to change the list of users who are allowed to work with disk
|
|
units.</p>
|
|
|
|
<h3>Required Parameter Group</h3>

<dl>
|
|
<dt><strong>Session handle</strong></dt>

|

<dd>INPUT; CHAR(8)
|
|
|
|
<p>The unique ID that was returned to the client on a preceding Start DASD
|
|
Management Session (QYASSDMS) API. The session handle contains arbitrary binary
|
|
data and should not be interpreted as character data.</p>
|
|
|
|
<p>If the session handle is not used to perform an operation using this API or
|
|
is not used to check the status of an operation using the QYASRDMS API within 5
|
|
minutes after a session is started or an operation has completed, the session
|
|
of the associated handle will be ended and the associated handle will be
|
|
invalidated if a call is made to start another disk management session.</p>

<p>The following is a description of each operation:</p>
|
|
|
|
<dl>
|
|
<dt><strong>Change the storage threshold percentage of an ASP</strong></dt>
|
|
|
|
<dd>The storage threshold for an ASP determines when the system warns you that
|
|
the space allocated for the ASP is almost full. It specifies a percentage of
|
|
used ASP storage space. This operation changes the storage threshold
|
|
percentage.<br>
|
|
<br>
|
|
</dd>
|
|
|
|
<dt><strong>Add disk units to an ASP</strong></dt>
|
|
|
|
<dd>This operation allows you to add disk units to an ASP. If the ASP does not
|
|
exist, it will be created. The ASP balancing function can be called optionally.
|
|
The ASP balancing function improves disk performance by balancing disk
|
|
utilization across all of the disk units in an ASP.<br>
|
|
<br>
|
|
</dd>
|
|
|
|
<dt><strong>Suspend mirrored protection on a disk unit</strong></dt>
|
|
|
|
<dd>When mirrored protection is configured for an ASP, this operation suspends
|
|
mirrored protection on a disk unit in the ASP. This operation is required to
|
|
replace a disk unit in an ASP that is mirrored protected.
|
|
|
|
<p>Sometimes mirrored protection may be suspended automatically when a disk
|
|
unit fails. In the situation where mirrored protection is already suspended and
|
|
this operation is called, a successful completion code will still be
|
|
returned.</p>
|
|
</dd>
|
|
|
|
<dt><strong>Resume mirrored protection on a disk unit</strong></dt>
|
|
|
|
<dd>This operation synchronizes data in a mirrored pair of disk units where
|
|
mirrored protection has been suspended and then resumes mirrored protection.
|
|
|
|
<p>If mirrored protection has already been resumed and this operation is
|
|
called, a successful completion code will still be returned.</p>
|
|
</dd>
|
|
|
|
<dt><strong>Include a disk unit in device parity protection</strong></dt>

operation rebuilds data that existed on the failed disk unit onto the new disk

unit.<br>

<dt><strong>Replace a mirrored disk unit</strong></dt>
|

|
|
<dd>When a disk unit in a mirrored pair has failed, it can be replaced using
|
|
this operation.
|
|
|
|
<p>A disk unit selected to replace the failed mirrored disk unit must satisfy
|
|
all of the mirrored protection configuration rules and restrictions when it is
|
|
paired with the remaining disk unit in the mirrored pair.</p>
