We're running Exchange 2007 SP1 in SCC config. All connected to EMC SAN. Unfortunately, due to some routine work last night, some of the LUN's went down without warning.
Once the LUN's came back up again, most of the mailbox stores remounted automatically. Unfortunately, there are about two where we can't manually mount the store.
The message is that there is a log file missing.
We ran ESEUtil /mh on the store and, yes, it's in Dirty Shutdown with missing log files. Also, events logged in the App Viewer stating this too.
Bizarrely, running ESEUtil /ml shows that all log files are present and intact.
So we renamed the checkpoint on one database, then it remounted fine.
Can anyone explain why this was?
