IBM Midrange System Storage Hardware Guide
Manage Enclosure Alarms is used to respond to an alarm on the storage subsystem. If a
critical failure of the storage subsystem or the enclosures occurs, then an audible alarm will
sound if it is enabled.
The audible alarm is just one of three ways in which Storage Manager will inform you of a
fault. The other two are that the Alarm button becomes animated and the Recovery Guru
button in the toolbar appears.
By default, the alarm is disabled, but this can be changed by the Storage Manager client. This
can be done on all enclosures or individual enclosures and controllers (Figure 4-38). The two
options are to always sound an alarm or never sound an alarm.
The lower part of the window shows the alarms that are already sounding, which can be
silenced by clicking the Silence Alarm(s) button.

4.8.5 Updating the controller microcode
Before you use your DS5000 storage subsystem to process production data, update the
firmware (or microcode) of your DS5000 storage subsystem to prevent any unnecessary,
known failures, and make use of the latest improvements. New firmware might be required
when installing a new version of the Storage Manager software. Check the IBM support Web
site for available updates at the following address:
