Suspending and resuming LCR for an Exchange 2007 storage group

Learn how to suspend and resume Local Continuous Replication (LCR) via the EMC or ESM for an Exchange 2007 storage group that has become unavailable.

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.

You are reading part 5 from "Managing Local Continuous Replication in Exchange 2007," excerpted from Chapter 8 of the book "How to Cheat at Configuring Exchange Server 2007: Including Outlook Web, Mobile, and Voice Access," by Henrik Walther, copyright 2007, published by Syngress, a division of Elsevier.
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."
