The Availability Manager with the NAS Extension uses standard ICMP (Ping) and SNMP probes to determine device status and containment information. In addition, the NAS Extension uses an HTTPS Adapter to gather configuration information about Celerra Control Station devices, and some post-processing steps to complete the topology creation.

File Servers present in different networks can be discovered in different IP Managers. During post-processing the fileservers are related to the NASChassis.


The internal Celerra IP network (the IP network that supports communication between file servers and the control station hosts) is automatically excluded from discovery.
