Create seed files in the IP Availability Managers

The Topology Split Manager forwards the list of devices in each seed file in the local/logs directory to the appropriate IP Availability Manager. There, under the control of the Topology Split Manager, the IP Availability Manager creates a seed file in its local/logs directory and populates the file with the list of devices from the Topology Split Manager.

The Topology Split Manager directs the IP Availability Manager to add the string “update” to the name of the seed file that it creates. For example, if the name of the source seed file in the Topology Split Manager is seedfile-AM001-1138291391, the IP Availability Manager will name the seed file seedfile- update- AM001-1138291391.

The Topology Split Manager obtains a list of discovered devices from the IP Availability Manager and then calculates the differences between the actual devices that were previously discovered by the IP Availability Manager and the devices that are assigned to the IP Availability Manager by the topology-split algorithm. The Topology Split Manager uses this information to organize the devices in the IP Availability Manager-created seed file, hereafter called the domain’s seed file, as “New Seeds,” “Unmanaged Seeds,” or “Outdated Seeds.”

“New Seeds” contains an entry for each managed device (IsManaged attribute = TRUE) that is assigned by the topology-split algorithm (as either an owned or proxy device) to the IP Availability Manager and is not already in the IP Availability Manager’s topology.

“Unmanaged Seeds” contains an entry for each unmanaged device (IsManaged attribute = FALSE) that is assigned by the topology-split algorithm (as either an owned or proxy device) to the IP Availability Manager. The entries in “Unmanaged Seeds” are commented-out.

“Outdated Seeds” contains an entry for each device (owned or proxy) that is already in the in the IP Availability Manager’s topology and is either not assigned by the topology-split algorithm or is assigned and is unmanaged. The entries in “Outdated Seeds” are commented-out.

The IP Availability Manager will discover only the devices in “New Seeds.”

If topology synchronization is successful, a user does not have to do anything with a domain’s seed file.
