Replacing HDDs in MMS Servers
Overview
The AMX line of MAX-MMS servers support hot-swappable hard disk drives (HDDs),
accessible behind the removable faceplate, on the front panel. Typically a new HDD
will be required only if an existing one has failed. Only HDDs provided by AMX can be
used as replacements in MMS servers, and in order to replace a HDD in an MMS
server, the drive must be installed and authenticated according to the steps outlined in
this document.
•
The MMS-01S, MMS-02S, MMS-04S and MMS-12S servers all utilize 250GB
hard drives, and require the MMS-HDD250G 250GB drive (FG 2178-250) for
replacements.
Degraded
•
The MMS-900 server utilizes 300GB hard drives, and requires the
MMS-HDD300G 300GB drive (FG 2178-300) for replacements.
There are several operations that are required to successfully replace an HDD in a
MMS server, all off which are described in this document:
1.
2.
3.
The physical removal of the damaged HDD, and the subsequent installation of
the replacement HDD.
A rebuild of the RAID array on the new HDD (required in order to add it to the
server’s RAID array).
Authentication of the new HDD with the MMS server. Note that before the HDD
can be authenticated to the server it must first be added into the array.
Note: The MMS-01S server does not utilize a RAID disk-drive system. In this case
there is no need to rebuild the array (as described below), but the replacement HDD
still needs to be authenticated (see “Step 4: Authenticate the New HDD” below).
Step 1: Identify the Drive That Needs To Be Replaced
To identify the drive that needs to be replaced, you’ll use the server’s built-in Disk
Management Utility tool. This requires that you have a PC connected to the MMS:

•
If you intend to connect to the MMS via a LAN connection, verify that the PC is
communicating properly with the network.
5.
Note the Port Number of the Degraded drive, and determine which physical
drive needs to be replaced in the server, based on the charts in FIG. 3:
•
Use an RJ-45 twisted pair cable to connect the Ethernet port on the MMS to the
LAN that your PC is on.
Once you have established communication between the MMS server and your PC,
you’ll use your web browser to access the server’s Disk Management Utility interface
to see which port has failed. You’ll need this information to identify the physical HDD
that needs to be pulled from the unit and replaced:
PORT 0
PORT 1
PORT 2
PORT 3
MMS-04S (front)
MMS-12S (front)
1.
2.
Launch a web browser (i.e. Internet Explorer).
PORT 2
PORT 1
PORT 0
PORT 5
PORT 4
PORT 3
PORT 8
PORT 7
PORT 6
PORT 11
PORT 10
PORT 9
Enter the IP address of the target MMS server in the address bar (example:
http://192.168.1.30:1080). You can use the WinMAX program to determine the
server’s IP address (displayed in the System Information tab).
Don’t forget to include the port number.
Note: If you are using Mozilla as your browser, you’ll need to override the secu-
rity that blocks port 1080. To unblock port 1080, add the following line (located at
/usr/lib/mozilla/defaults/pref/all.js):
PORT 0
PORT 1
PORT 2
PORT 3
PORT 4
PORT 5
PORT 6
PORT 7
PORT 8
PORT 9
PORT 10
PORT 11
PORT 12
PORT 13
PORT 14
PORT 15
PORT 16
PORT 17
PORT 18
PORT 19
PORT 20
PORT 21
PORT 22
PORT 23

Also note that the LED on the degraded drive should blink to indicate that it needs to
be replaced.
Once you have determined which drive needs to be replaced, you can proceed to
physically removing the bad drive, and installing the replacement drive (see reverse).
Step 2: Physical Removal and Replacement of the Drives

4.
Click on the Configure tab at the top of the screen to access the Configure page
(FIG. 2) which lists all drives in each array and their status. If a drive has failed, it
will be labeled “Degraded” rather than “OK”.
Flip the hinged front panel out,
and use it as a handle to pull the
drive/tray assembly out of its slot.
