Selective Discovery Filter
The selective discovery filter allows you to filter the devices that are passed from HP SIM to HP
Storage Essentials for discovery operations. The filter is a file that contains a list of IP addresses that
should (or should not) be passed to HP Storage Essentials. The filter does not affect device
discovery operations in HP SIM, it only restricts the data that is passed from HP SIM to HP Storage
Essentials. The filter examines each device HP SIM discovers before passing the discovery
information to HP Storage Essentials. In the case of multi-homed devices, the filter operation uses all
reported IP addresses for a given device in deciding whether or not to pass data to HP Storage
Essentials.
The selective discovery filter file is called SEDiscoveryFilterList (with no file extension). The
file resides in:
• <HP SIM install directory>/config on Windows
• /etc/opt/mx/config on Linux
A sample file called SEDiscoveryFilterList.sample is available.
NOTE: The sample file is located in <HP SIM install directory>/config on Windows
and /opt/mx/config on Linux.
Editing Rules for the Selective Discovery Filter
Use the following rules when editing the selective discovery filter:
• If you edit the selective discovery filter on a Windows system, do not use Notepad because it
will not preserve the file formatting.
• If you want to edit the selective discovery filter file at run time, set the following property to true
in the globalsetting.props file:
StorageEssentialsDiscoveryFilterReload=true.
