Follow the prompts to initialize the cluster(s).<br />

Output similar to the following should appear:<br />

Connecting to host "localhost", protocol "tcp", prog 0x20000004<br />

Initializing the cluster<br />

The cluster was initialized successfully<br />

System Configuration<br />

The cluster ID should now be set on the ContentDirector, and the programs should begin to execute<br />

in sequence.<br />

Verifying Cluster Connectivity<br />

To verify cluster connectivity:<br />

1. Make sure that the ContentServers have been acquired by typing the following:<br />

sudo /opt/omcld/bin/ssmdiag -s<br />

You should output similar to the following:<br />

SSID=0 SN=S00007E6A1.0 MGRAID3000 10.4.252.12 10.4.252.15 GB=253/9264 SC=47229<br />

SSID=1 SN=J00007E6A2.0 MGRAID3000 10.4.252.13 10.4.252.16 GB=253/9264 SC=47241<br />

SSID=2 SN=S0000FE6B1.0 MGRAID3000 10.4.252.32 10.4.252.35 GB=253/9264 SC=45606<br />

SSID=3 SN=J0000FE6B2.0 MGRAID3000 10.4.252.33 10.4.252.36 GB=253/9264 SC=47188<br />

2. Verify the output, by doing the following:<br />

a. Verify that the correct number of ContentServers have been discovered.<br />

b. Verify that all the ContentServers have non-empty serial numbers in the SN=0XXXX column.<br />

c. Verify that all the ContentServers have a non-zero pair of IP addresses. If a single IP address is all<br />

zeros (0.0.0.0), check the Ethernet connections on that ContentServer.<br />

d. Verify that there are no “x”s in the left-most column of the listing. An x indicates that a<br />

ContentServer is not responding and is an error condition. If any ContentServer is marked with<br />

an “x”, check the physical connections to the ContentServer and that it is powered on. Reissue the<br />

“ssmdiag” command. Contact <strong>Omneon</strong> Technical Support for troubleshooting help if the “x”<br />

persists.<br />

e. Verify that all ContentServers have 0GB allocated in the GB=0/XXXX column.<br />

f. Verify that all ContentServers have 0 slices allocated in the SC=0 column.<br />

g. If any ContentServers do not appear to be empty, contact <strong>Omneon</strong> Technical Support for<br />

instructions on clearing those ContentServers.<br />

Setting the <strong>Omneon</strong> <strong>MediaGrid</strong> System Time<br />

<strong>Omneon</strong> <strong>MediaGrid</strong> requires a common time reference for all of its components, which is important<br />

for file stamps and log messages. Complete the following process to set the system time and to<br />

synchronize the components. This command forces the system time to be set against an external NTP<br />

server.<br />
