<div class="section"><img src="./delta.gif" alt="Start of change" /><h4 class="sectiontitle">Suspend with tracking</h4><p>If you suspend
|
||
|
|
with tracking, the system will attempt to track changes made to those disk
|
||
|
|
pools. This may shorten the length of the synchronization process by performing
|
||
|
|
partial synchronization when you resume geographic mirroring. If tracking
|
||
|
|
space is exhausted, then when you resume geographic mirroring, complete synchronization
|
||
|
|
is required.</p>

<div class="section"><img src="./delta.gif" alt="Start of change" /><h4 class="sectiontitle">Suspend without tracking</h4><p>If you suspend

without tracking, then when you resume geographic mirroring, complete synchronization

occurs. </p>

<div class="note"><span class="notetitle">Note:</span> If you suspend geographic mirroring without tracking changes,

then when you resume geographic mirroring, a complete synchronization is required

between the production and mirror copies. If you suspend geographic mirroring
|
||
|
|
and you do track changes, then only a partial synchronization is required.
|
||
|
|
Complete synchronization can be a very lengthy process, anywhere from one
|
||
|
|
to several hours or longer. The length of time it takes to synchronize is
|
||
|
|
dependent on the number and type of disk units as well as how many TCP/IP

communication interfaces are dedicated to geographic mirroring. </div>
