HP MPX200 Multifunction Router - Manual (Page 68)

Acknowledging online, local migration jobs
When initial copy jobs for online, local migration are completed, HP mpx Manager transitions the
migration jobs to the Completed Data Migration Job page. While online local migration jobs are
in the Copy Complete state the MPX200 is updating both the source and destination LUNs with
any write I/O's from the host.
Completed online local migration jobs can only be acknowledged after the server is offline and
the source LUN is unpresented to the server.
When you acknowledge an online, local data migration job, HP mpx Manager provides final
synchronization of data between the source and destination LUN.
To acknowledge a completed online, local data migration job:
1.
In the left pane of HP mpx Manager, click the Services tab, and in the left pane under a blade
node, click Data Migration Jobs.
2. In the right pane, click the Completed Data Migration Jobs tab to bring that page to the front.
3. On the Completed Data Migration Jobs page in the % Completed column, right-click a job
that is specified as 100%.
4. On the shortcut menu, click Acknowledge Completed Data Migration.
5. On the Confirm Acknowledgement dialog box, click Yes.
Acknowledging online, remote migration jobs
When initial copy jobs for online, remote migration are completed, HP mpx Manager transitions
the migration jobs to the Synchronizing Jobs Group page. While online remote migration jobs are
in the Syncronizing state the MPX200 is updating both the source and destination LUNs with any
write I/O's from the host. Completed online remote migration jobs can only be acknowledged
after the server is offline and the source LUN is unpresented to the server.
When you acknowledge an online, remote data migration job, HP mpx Manager provides final
synchronization of data between the source and destination LUN. Because an online remote
migration job acts as an asynchronous mirror operation, a large number of dirty regions (blocks)
may remain unsynchronized, depending on the change rate of the data. Before planning server
and application down time, it is essential that you monitor how many dirty blocks are remaining.
Depending on the number of dirty blocks and the available WAN bandwidth, the time to complete
final synchronization may vary.
Figure 33 (page 68) shows the Synchronizing Jobs Group page.
