A method for a guaranteeing a network manager discovers SNMP agents on a communications network. Each SNMP agent transmits a trap to the network manager. The trap contains the network manager's IP address and the SNMP agent's identifying information, including its IP address. When the trap is received at the network manager, it is parsed for the agent identifying information, which is compared against a list of previously identified/discovered agents. If the agent identifying information is not found, i.e., if the agent is a newly discovered agent, the network manager adds the agent to the list of discovered agents. The agent is then registered/stored in the discovered agents file. When the trap does not include sufficient identifying information, the network manager sends a query to the agent to extract additional identifying information. The system manager is thus able to discover all connected agents without broadcasting a query message.

A method and system for providing access to a protected partition of a direct access storage device in a data processing system which includes a direct access storage device, an adapter that commands I/O of the storage device and also contains a protection mechanism that restricts access to a memory partition on the storage device, an adapter device driver for controlling the adapter, and a system block device driver for transferring I/O commands to the system partition from the operating system to the adapter device driver. The method comprises the steps of receiving a request to perform a read or write to a protected memory partition, generating a command data block directing the storage device to perform the read or write, and generating a passthru command containing the command data block that directs the adapter to send the command data block without enforcing the protection of the memory partition. The method continues by sending the passthru command to the adapter which then passes the command data block on to the storage device to be executed without enforcing the memory partition protection.

An information handling network includes a plurality of information processing systems having a pretermit system configuration operating under the control of a corresponding number of operating systems where during a initial microcode load (IML) period prior to loading the operating systems a change in the system configuration is detected based on the predetermined system configuration. Upon detecting the change, a communication adaptor device is activated for communicating certain configuration information over the network before loading the operating system.
