Mirroring operation
On system power-up — e.g., at initial installation or whenever a drive is replaced — the M3 will first verify that
each drive is an ESI-formatted drive. If so, it then will transfer all data from the primary drive to the mirroring
drive. This process can take anywhere from a few minutes to one hour, depending on system activity, amount
of voice message storage, and configuration. System operation won’t be affected during the data transfer,
because this transfer will occur only when call-processing is making no disk drive access requests.
If a primary drive is replaced, data will be copied in the same fashion from the mirror drive to the new primary
drive. Again, the replacement drive must be a new, unprogrammed ESI drive. If it’s not, the system may
copy all data in the wrong direction — i.e., from the new (mostly empty) primary drive to the mirror drive!
Therefore, ESI recommends that the mirror drive be moved to the primary drive mounting position and the
new drive be mounted on the mirror drive mounting position.
Note: Once a hard drive has been copied, if it is removed and installed on a different system, the system will
automatically initialize the drive, erasing all data and voice messages.
Panel indicators and controls
The M3 panel indicators and Reset/Test button are used primarily for alarm and error
indication and troubleshooting. If the M3 is installed properly and the ESI Communications
Server is powered-on, the M3’s Power LED will always be lit. The following table describes
other M3 indications:
“Primary”

“Mirror”

“Error”

The Reset/Test button is used to mute the audible alarm if a failure or error occurs. Additionally, during
normal operation, you may test the M3 panel indicators by pressing and holding Reset/Test for more than
one second. This will turn on all of the M3’s LEDs and sound the audible alarm until you release the
Reset/Test button.
