<div><p>Each logical partition requires a load source disk unit. </p>
|

|
|
<p>The load source contains the Licensed Internal Code. The server uses the
|
||
|
|
load source to start the partition. Each secondary partition has a specific
|
||
|
|
slot placement for its load source depending on the type of system unit or
|
||
|
|
expansion unit where it is installed. An IOP and IOA is then required to control
|
||
|
|
the load source disk unit for each partition.</p>

<p>You should be aware of these rules for secondary partition load source
|
||
|
|
placement:</p>
|
||
|
|
<ul><li>You specify the load source IOP when you create your partition.</li>
|
||
|
|
<li>Disk compression must be disabled for the load source disk.</li>
|
||
|
|
<li>Disk units must have at least 1GB of usable capacity.<div class="attention"><span class="attentiontitle">Attention:</span> A
|
||
|
|
parity-protected 1GB file (6602 or 6605) cannot be used.</div>
|
||
|
|
</li>
|
||
|
|
<li>Disk mirroring requires two load source disk devices in valid load source
|
||
|
|
positions.</li>
|
||
|
|
<li>External disk units can not be used.</li>
|
||
|
|
<li>Any disk IOP or IOAs that can attach to a system capable of having logical
|
||
|
|
partitions can be used for additional storage capacity once the special requirements
|
||
|
|
for load source disk are met.</li>
|
||
|
|
<li>Each partition has its own single level storage and hence its own ASP
|
||
|
|
configuration. The same rules for ASP configuration apply within a partition
|
||
|
|
as apply on a system without logical partitions.</li>
|
||
|
|
<li>Disk protection can be defined for a partition in the same way as for
|
||
|
|
a non-partitioned system: parity protection (RAID), mirroring, or mixed. Bus-level
|
||
|
|
mirroring requires two buses in the partition. IOP-level partitioning requires
|
||
|
|
two disk IOPs in the partition.</li>
|
||
|
|
<li>Disk units that are already in use by a logical partition can not be added
|
||
|
|
to a different logical partition. You must first remove them from the configuration
|
||
|
|
of the partition that is using the disk units before adding the disk units
|
||
|
|
to a different partition. In doing this, the system automatically moves any
|
||
|
|
user or system data to other disk units in the same ASP.</li>
|
||
|
|
<li> For a 5094 or 5294, you can attach load source disk units to a maximum
|
||
|
|
of 9 storage IOAs. Also, a 5094 or 5294 can have load source disk units for
|
||
|
|
up to six secondary partitions. </li>
