76 IBM Systems Director Management Console: Introduction and Overview
5.1 System discovery
Discovery is the process by which IBM Systems Director identifies and
establishes connections with the network-level resources that the SDMC can
manage. You can use system discovery or advanced system discovery to
identify resources within your environment, collect data about the resources, and
establish connections with the resource.
SDMC uses the Service Location Protocol (SLP) for discovering resources in the
network. SDMC supports the discovery of servers or Flexible Service Processors
(FSP), frames or Bulk Power Controllers (BPC), and operating systems.
Discovery of operating systems is not necessary if you want to manage only
Power resources. SDMC discovery also supports FSP and BPC redundancy.
The discovery in SDMC is a two step process compared to the one step process
in HMC. In HMC, you can perform a single step of “Add Managed System” task
to discover, where as in SDMC, you have to perform the following two steps:
1. System discovery
2. Request access
After a system has been discovered, it is displayed under Hosts on the
Resources tab of the Welcome page. You can manage a system only after
discovering it and successfully requesting access to it.
5.1.1 System discovery functions
System discovery is useful when you want to discover a resource for a single IP
address or host name, discover resources of the same type for a range of IP
addresses, or use a discovery profile. Discovery profiles enable you to customize
discoveries, including importing IP addresses and requesting access to
discovered resources.
System discovery provides the following functions:
򐂰 Discovery based on a single IP address (IPv4 or IPv6)
򐂰 Discovery based on a range of IP addresses (IPv4 or IPv6)
򐂰 Discovery based on a host name
򐂰 Discovery based on a resource type
򐂰 Scheduling discovery to run on recurring basis
