Suspending and resuming LCR for an Exchange 2007 storage group |

On occasion, you might need to suspend LCR for a storage group. You need to suspend
LCR should either the active or passive storage group copy for some reason become
unavailable. Suspending LCR is also necessary if you need to seed the LCR copy (seeding is
covered next in this chapter). Finally, you need to suspend LCR when you're performing an
integrity check on the passive copy's transaction logs and database file, which is a recommended
practice now and then.
| Note: Suspending LCR means that all log file shipping as well as log file replaying is halted. Suspending LCR is a straightforward process; it's done by selecting the
respective storage group in the EMC, then clicking Suspend Local continuous
replication in the Action pane. When you click this link, you'll need to confirm
that you really want to suspend LCR. In addition, you'll have the option
of specifying why LCR was suspended. This comment can be viewed by
clicking the View Comment button on the Properties page of the storage
group (shown in Figure 8.17). |

If you'd rather to suspend LCR for a storage group via the EMS, you'll need to do so
using the Suspend-Storage, GroupCopy CMDlet. To suspend LCR for the First Storage Group,
where the comment shown in Figure 8.17 is specified, you should run the following command:
Suspend-StorageGroupCopy -Identity "First Storage Group" -SuspendComment
"Suspending LCR as an integrity check on the passive copy's transaction logs and
database file is required."
Again, you need to confirm that you really want to suspend LCR for the storage group.
To do so, type Y for Yes and press Enter.
When the active or passive storage group is available again or when you have performed the
integrity check or whatever type of maintenance you have completed, you need to resume
LCR for the storage group. Again, this can be done via either the EMC or the EMS. To perform
this task using the EMC, select the respective storage group and click Resume local
continuous replication in the Action pane. When you do, the warning message shown in
Figure 8.18 will appear. Click Yes and watch the Copy Status change to Healthy once
again. Both log file shipping and log file replay have now been resumed.

To resume LCR for a storage group via the EMS, type Resume-StorageGroupCopy
-Identity "First Storage Group."
