Page 20: About Clusters, Volumes And Groups
Harmonic MediaGrid supports using replication on systems with the ContentServer 3000 Series. This feature provides an additional level of data protection by allowing you to set up a Harmonic MediaGrid system across two different sites and replicate data across sites. This configuration is known as a “stretch cluster.

Before installing your Harmonic MediaGrid system, you must allocate an IP address range for the Harmonic MediaGrid Public VLAN. The Public VLAN is an IP subnet, which will be visible by all parts of the network that access the Harmonic MediaGrid. Make sure the Public VLAN is dedicated to Harmonic MediaGrid components, and accessible by clients that will access the Harmonic MediaGrid.
Page 24: Private Vlans
Network Configuration Private VLANs Before installing your Harmonic MediaGrid system, you must also allocate IP address ranges for two Private VLANs. The Private VLANs are private IP subnets that create redundant paths between the ContentDirectors, allowing them to communicate information and keeping them synchronized.

Cables and Mounting Hardware A rack mounting kit is provided with each Harmonic MediaGrid component, which provides the items needed to mount each component on a rack. Mounting instructions are also included. The type, quantity and length of the cables depends on the customer site and will likely differ for each separate installation.
Page 33: Racking Precautions
Racking Precautions for the ContentStore 5840. Safe handling of this system requires at least TWO people. Harmonic recommends that you  use THREE people to rack mount a system; two to lift and one to help guide the system onto the rack rails.
Page 34 Chapter 2 System Installation with the Content- Racking Precautions Server 4000 Series IMPORTANT: Use only the power cables provided by Harmonic. IMPORTANT: The ContentServer and ContentStore 4000 series must be connected to reliable grounding before applying power. IMPORTANT: The ContentServer and ContentStore 4000 series will not receive sufficient airflow or cooling if it is operated with any of the front or rear modules missing.

“99” are valid. Enabling Directories with More than 15 Levels With version 3.4 and later, you may enable your Harmonic MediaGrid file system to contain directories with more than 1 5 levels. CAUTION: Before enabling this support, please note that moving to an earlier release after having created directories deeper than 15 levels is not supported.
Page 207: Disabling Directories With More Than 15 Levels
NOTE: Any ContentDirectors, which start up while the current cluster members are down will not receive the changes so Harmonic recommends first having all ContentDirectors running at this point. Client applications will now be able to create directories whose depth is only limited by the overall path limit (1024 bytes, which will be fewer than 1024 characters for non-ASCII character sets).
Page 208: Using Mgcopy To Copy Files Between Harmonic Mediagrid Systems
-bash: cd: d/d: No such file or directory Using mgcopy to Copy Files Between Harmonic MediaGrid Systems The mgcopy utility allows you to copy data quickly between Harmonic MediaGrid systems. This utility can be used any time you wish to back up data quickly.
Page 209 Chapter 7 Administrative Procedures Using mgcopy to Copy Files Between Harmonic MediaGrid Systems When opened, mgcopy presents a command line interface. Use the mgcopy command with additional values shown in Table 7–1 to perform a copy. Note the following usage:...
Page 210 Used with other options like copyAcl and copyOwner, but does not copy data at destination -testRun Do a test run of the command to see if the version of source and destination Harmonic MediaGrids are compatible with each other Debug level (default: 0)

The mgquota utility is installed and run on a Mac FSD client and displays quota information for a given Harmonic MediaGrid directory. It does not allow you to set a quota; it merely reports the quota for the specified directory. For information on setting a quota, refer to the Harmonic ContentManager User’s Guide.

The archive depth is presently 1 3 files deep but can be configured to archive more files. Harmonic MediaGrid breaks the log files out by IP address for each of the devices in the cluster. ContentServers have two log files so long as the IP interfaces are up and active.
Page 282: Verifying The Dhcp Server Is Running On The Contentdirectors
Verifying the DHCP Server Is Running on the ContentDirectors The first two ContentDirectors in a Harmonic MediaGrid have DHCP servers running on them and they are configured as peers. This means that either of the ContentDirectors can respond to a DHCP request and the servers should communicate the IP address that they have assigned to a request to the other DHCP server.
Page 283: Checking Log Files For Errors
[root@CDL1 dhcp]# pgrep dhcpd 3027 As mentioned before, the DHCP servers in the Harmonic MediaGrid are configured in a peer relationship. Both servers have to be up or one must timeout and wait for the other to come online. In the output of /var/log/messages below, the communication between ContentDirector1 (shown as CLD1) and ContentDirector2 (shown as CLD2) has been interrupted.
Page 284: Network Time Protocol (Ntp)
Network Time Protocol, or NTP, is a way of updating the time on a computer to a known time reference.

To synchronize time between ContentDirectors, the ntp.conf file on all ContentDirectors in the Harmonic MediaGrid are...
Page 285: Troubleshooting On The Contentbridge
“ntpdate -u” can then be initiated on ContentDirectors that are receiving the above error message. Troubleshooting on the ContentBridge The ContentBridge provides access to the Harmonic MediaGrid for clients not running the FSD or clients that need to access the Harmonic MediaGrid via FTP. ContentBridge Mounts to the Harmonic MediaGrid The primary problem experienced with the ContentBridge occurs when the Harmonic MediaGrid file system has not been mounted.
Page 286: Contentbridge Configuration Files
In addition to the config file on the first two ContentDirectors, there is a gateway file for each ContentBridge in the Harmonic MediaGrid. The file name for the gateway file is CLBnnnnn and is case sensitive. The five n’s reflect the last five digits of the serial number of the ContentBridge.
Page 287: Contentbridge Services
NOTE: If you are using a name instead of an IP address for the ContentBridge, make sure you can ping the name. If not, DNS is not configured correctly. NOTE: Note that lines starting with “MG” or “CI” are for access via the Harmonic Media API, and lines starting with “CB” are for access via CIFS/SMB or FTP.

Page 328: Appendix B Contentdirector Limits
Harmonic MediaGrid release 3.1 and later. This section provides an explanation of the implementation of ContentDirector limits in Harmonic MediaGrid 3.1 and later as well as information needed to plan the capacity and monitor resource consumption of Harmonic MediaGrid system.
Page 329 * Standard ContentDirectors with file counts greater than 1 million are supported when upgraded to Harmonic MediaGrid 3.1 or later provided that the other limits are met. However, load and restart times will increase as file counts increase beyond the recommended limit. To improve load and restart times with file counts beyond the recommended limit, upgrade to the High- Performance ContentDirector.
Page 330: Resource Limits
FileTable space. SliceTable Slices Harmonic MediaGrid 3.1 or later manages the size of its SliceTable in terms of the count of distinct slices. In systems using replication, the SliceTable only counts 1 for all copies of a slice.
