NOTE: The key icon is displayed next to the fabric only if authentication is successful for all the switches
in the fabric.
Running a subnet scan (fabric scan)
You can use Fabric Manager to scan a subnet and discover fabrics. A subnet scan eliminates the need to
know the exact address of a switch to discover a fabric. Fabric Manager lists the switches and fabrics that
it finds during the subnet scan. You can then add them to Fabric Manager in the SAN Elements tab. See
”Discovering a fabric” on page 55 for information on adding them to Fabric Manager.
NOTE: Switches might appear in your subnet scan even after you unplug the Ethernet cables of those
switches.
To run a subnet scan:
1. Select Discovery > Subnet scan or click the icon from the tool bar.
The Subnet scan dialog box opens (see Figure 18).
Figure 18 Subnet scan
2. Enter the first three sets of digits of an IP address in the first three sections of the IP Address Range field.
3. Enter a wildcard in the last section of the IP Address Range field to represent the range of the scan. For
example:
• 192.168.168.*: Discovers any fabric in the address range of 192.168.168.0 through
192.168.168.255.
• 192.168.168.1**: Discovers any fabric in the address range of 192.168.168.100 through
192.168.168.199.
• 192.168.168.11*: Discovers any fabric in the address range of 192.168.168.110 through
192.168.168.119.
• 192.168.168.25*: Discovers any fabric in the address range of 192.168.168.250 through
192.168.168.255.
NOTE: The number before the * can be any number as long as the resulting range is greater than 0 and
less than 255. You cannot enter 192.168.168.3** or 192.168.168.26*.
4. Click Scan.
The result of the scan is a list of switches and fabrics (see Figure 19). Fabrics are indicated with two
angle brackets (>>) adjacent to the switch IP address. If you click a fabric, the list expands to include
the switches in the fabric.
The switch name is listed next to the switch IP address, and the number of switches in the fabric are also
displayed.
5. To add a switch or fabric to Fabric Manager in the SAN Elements tab, click the check box next to the
element, and then click Add.
