If you experience a hard disk failure on a Storage Attached Network (SAN) device that is used to store the database files for a computer that is running Microsoft Exchange Server 5.5 or Microsoft Exchange Server 2003, you may experience all the following symptoms:
This problem occurs because the Message Transfer Agent service continues to run on the affected Exchange Server 5.5 computer. This behavior occurs even if the SAN storage device hard disk fails. Because the message transfer agent (MTA) is available for remote procedure call (RPC) communication, the sending server transfers messages to the affected Exchange Server 5.5 computer.
In this scenario, the affected Exchange Server 5.5 computer performs a delayed write operation when it receives a message. After the affected server performs the delayed write operation, it sends an acknowledgement to the sending server. The acknowledgement indicates that the affected server has received the message successfully. After receiving the acknowledgement, the sending server removes the message from the sending queue. However, when the affected server tries to physically write the message to the failed hard disk, it cannot do so. Therefore, the message is lost.
