3. Click Seed Switch.
If the fabric contains other switches that are running the latest version and are also
HTTP-reachable from the Management application, the Seed Switch dialog box appears.
Otherwise, a message displays that you cannot change the seed switch.
4. Select a switch to be the new seed switch from the Seed Switch dialog box.
You can select only one switch. Only switches that are running the latest Fabric OS version in
the fabric are displayed. The current seed switch is not displayed in this list.
5. Click OK on the Seed Switch dialog box.
If you are not already logged in to the seed switch, the Fabric Login dialog box displays.
If you are successfully authenticated, the fabric is deleted from the Management application
without purging historical data, and the same fabric is rediscovered with the new seed switch.

IP discovery overview
NOTE
Discovery only displays products that are assigned to your area of responsibility (AOR). For more
information about user accounts, refer to
“Areas of responsibility” on page 250.
NOTE
You must have the Discover Setup - IP privilege to configure and run discovery. For more information
about privileges, refer to
“User Privileges” on page 1935.
NOTE
You must have the All IP Products AOR (area of responsibility) in your user account to discover new
products. For more information about user accounts, refer to
“User accounts” on page 241.
NOTE
IP discovery requires Internet Control Message Protocol (ICMP) or Telnet support on the device to
determine device reachability.
NOTE
DCB devices discovered through Fabric discovery (from the SAN tab) are automatically added to IP
discovery during rediscovery.
Discovery is the method that the Management application uses to find data networking devices on
the network. When the Management application discovers devices, it finds all IP addresses on a
device and stores them in the Management application database. The Management application
uses the primary address of a product to communicate with the product. The primary address is
determined using the following rules:
• If you configure discovery to prefer loopback addresses (refer to “Defining global setting
preferences” on page 97), and there are loopback IP addresses configured in the product; and
the loopback IP address is reachable from the Management application server, then the
loopback IP address is the primary IP address of the product.
