To discover the IP configuration of a NAS device, the Availability Manager uses the HTTPS Adapter, which initiates a process contained within the NAS Extension. This XML-based probe associates the Data Movers with the Celerra Network Server via the Control Station.

After the initial discovery of the NAS IP elements by the IP Manager, the Availability Manager continuously monitors the status of these elements by periodically sending ICMP and SNMP polls to the IP devices. “NAS IP discovery” on page 240 provides more information. The “Discovery methods” on page 144 provides more information about the full IP discovery process.
