If you are using geographic
mirroring and want to access the mirror copy to perform save operations
or data mining, or to create reports, you must detach the mirror copy from
the production copy. You detach the mirror copy by accessing the production
copy of the disk pool.
Note: When you reattach the detached mirror copy, a complete synchronization
is required between the production and the mirror copies. Synchronization
can be a lengthy process.
To detach the mirror copy, follow these steps:
- It is recommended that you make the independent disk pool unavailable
to ensure the production copy is not altered while the detach is being performed.
See Make the independent
disk pool unavailable.
- In iSeries™ Navigator,
expand My Connections (or your active environment).
- Expand the server that owns the production copy of the disk pool from
which you want to detach the mirror copy.
- Expand .
- Right-click the production copy of the Disk Pool you
want to detach and select .
- If cannot be clicked, because it is disabled.
The mirror copy is not in sync with the production copy, so geographic mirroring
must be resumed, the disk pool varied on, and production and mirror copies
synchronized before the mirror copy can be detached.
Before you make the detached mirror copy
available, you should create
a second, unique device description for the independent disk pool that
differentiates it from the production copy. A separate device description
for the mirror copy prevents two instances of the same database in the network.
It will also simplify work done outside of iSeries Navigator. Use the detached mirror
copy device description to make the detached mirror copy available.
