/mcpDisk Capacity The information about the messages in a database and the message content is stored as files on the Unity Connection server. Depending on the number of Unity Connection users, the number and duration of messages they receive, and the settings that you specify for the message aging policy and for quotas, it may be possible for the hard disk on which messages and greetings are stored to fill up. This would cause Unity Connection to stop functioning. As the hard disk approaches maximum capacity, you may also encounter unexpected behavior. The disk capacity page describes the maximum capacity of the hard disk on which messages and greetings can be stored. The disk capacity can be managed in Cisco Unity Connection Administration> System Settings> Advanced> Disk Capacity. For more information, see Help> This Page. When the hard disk fills to the specified percentage limit, neither users nor outside callers are allowed to leave voice messages. Unity Connection also logs an error that can be viewed on the Tools > SysLog Viewer page in the Real-Time Monitoring Tool. You can still send a broadcast message even when the hard disk exceeds the specified limit. Note If the disk capacity settings are changed, you need to restart the Connection Message Transfer Agent service in Cisco Unity Connection Serviceability. If the hard disk exceeds the value that you specify, users should immediately delete unnecessary voice messages. In addition, to prevent a recurrence, you may want to re-evaluate message-aging policy and mailbox quotas. For more information, see the Controlling the Size of Mailboxes section of the Message Storage, on page 109 chapter.
