Issue with DAG DBs when storage fails on active node

Hi,

I am using 6 node DAG cluster in exchange 2010 sp1 RU5. I noticed that whenever a hard disk fails on any mailbox server which holds an active DB, it will dismount the same. I thought the DAG behaviour is to failover to another healthy DB when the mounted DB has disk failure.

In my case when the disk fails on mounted DB, it will get dismounted and all other DB copy will be in fail state. is it normal? any suggestion? thanks.

Thanks.
