230 Chapter 12 Monitoring the CallPilot server and resourcesMonitoring Multimedia File System volumesThe MMFS volumes store all voice and fax messages and other relatedmultimedia files, such as user mailboxes, greetings, voice prompts, andvoice menus. The server can have more than one volume, depending onthe overall capacity of the system to process calls. When an MMFS volumeis full, no new files can be created on that volume. If an MMFS volume hasless than 10 percent of disk space left, you must free up enough spaceto clear the alarms.Note: When you lower the retention period for user messages you donot affect the database. You must be clear about which parts of thehard disk (either the database or the MMFS) are approaching a pointwhere they are nearly full.What monitoring MMFS volumes involvesMonitoring MMFS volumes involves waiting for alarms to be raised asavailable disk space becomes limited. You can, however, display or printreports on MMFS volume disk usage using Reporter. These reportsindicate disk space usage patterns, which can help you to plan a strategyto deal with limited disk space. Alarms are raised as MMFS volumes fillup. Different alarms are raised, depending on how much disk space is leftfor the MMFS volume.Alarm Amount of space leftMajor less than 10%Critical less than 5%When alarms are raised, a warning box appears indicating the volume IDand the percentage full.Clearing alarmsAlarms are cleared when less than 88 percent of MMFS volume disk spaceis being used. To clear alarms, you must free up space on the MMFSvolume for which the alarm was raised.• If one MMFS volume is full while other volumes are empty, you canmove users’ mailboxes from the full volume to another one.• Disk space usage patterns on voice mail systems fluctuate, becausevoice messages are constantly created and deleted. If all volumesare filling up, you can do the following actions to reduce the size ofmailboxes:— Send a broadcast message asking users to delete unneededmessages.— Look at user usage reports to determine which users are using a lotof space, and talk to them about it.Nortel CallPilotAdministrator GuideNN44200-601 01.11 Standard5.0 9 November 2007Copyright © 2007, Nortel Networks.
