About Omneon MediaGrid - Harmonic Inc

Troubleshooting
The first three log files (ssmd, mdscore, and startup) are the most commonly utilized log files when
troubleshooting Omneon MediaGrid problems. The logs will rotate and be archived when they
approach or reach 250MB depending upon the system check which is performed hourly. The files are
archived with the format of filename.1.gz, filename.2.gz, etc. The exception to this is the remotelogs
files. The archive depth is presently 13 files deep but can be configured to archive more files.
Omneon 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.
Note that the information in log files is structured such that the information at the top of the file is
the most current and supersedes anything below it. For example, there may be multiple lease entries
for the same IP address, but the ones at the top of the file supersede the ones below it.

Log rotation for remotelog files is also based upon filesize as well and is set to 5MB. The archive depth
is set to 5 files and is also configurable.
DHCP Server Running on the ContentDirectors
The first two ContentDirectors in an Omneon 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. This communication between the DHCP servers ensures that the dhcp-leases
files that reside on both ContentDirectors are synchronized and have the same information about
client MAC address, etc.
