partitions on an IBM<sup>®</sup> iSeries™ server</h1>
|
|
<div><ul><li>A system that uses remote loadsource disk unit mirroring is only able
|
|
to perform an IPL from the disk unit attached to the load source IOP. If that
|
|
disk unit fails and cannot be repaired concurrently, the system cannot perform
|
|
an IPL until the failed load source is fixed and the recover remote loadsource
|
|
service procedure is performed. </li>
|
|
<li>When remote loadsource disk unit mirroring is active on a system and the
|
|
load source attached to the Load Source IOP fails, the system cannot perform
|
|
a main storage dump if the system ends abnormally. This means that the system
|
|
cannot use the main storage dump to reduce recovery time after a system fails.
|
|
It also means that the main storage dump is not available to diagnose the
|
|
problem that caused the system to end abnormally.</li>
