Exchange 2007: SCR replication repair

Last week I had to do some serious debuggingon storage copy replication. We discovered that one of our SCCclusters had decided to quit replicating to the SCRnode at the other site. We’re not sure why (we think it’s because the SCR node was rebooted and replication was not cleanly suspended), but the ramifications of failed replication are interesting. In the Exchange 2003 world, you had to depend on your backups running smoothly to purgelog filesfrom the log disks or else eventually, you’d find your databases dismounting in the middle of the day because you’re out of space.
