Fabric Discovery
4
To discover a fabric using a DNS name, you must have an entry in the hosts.txt file in
C:\WINDOWS\system2\driver\etc or in /etc on Unix-based machines. The entry should be on a
new line with the format switchIP switchName. For example 10.144.8.42 mySwitch. The switch
is discovered in Fabric Manager using the DNS name switchName as specified in the hosts.txt
file (mySwitch in the above example).
You do not need to include http:// before the IP address to discover a fabric.
3. Type the user name and password used to log in to the switch.
4. Click OK.
The fabric is discovered only if the authentication succeeds. Otherwise, you are prompted
again for a user name and password. Authentication fails if the user name or password is
invalid for the switch, if the password has expired, or if the account is locked out after too many
invalid login attempts. If the password has expired, you are prompted to either change the
password or provide different login credentials.
After the fabric is discovered, all the switches in the fabric are tested against the user name
and password. If any of the switches fails to authenticate, you are prompted to log in to the
switches that failed. If you choose not to log in, the Fabric Device Management Interface
(FDMI) and some data for the Fabric Inventory reports might not be available.
If you choose to not log in to the switches that failed, you can log in later by choosing Discovery
> Switch Login. If the seed switch is not running the latest Fabric OS version in the fabric, you
are prompted to change the seed switch.
Multiple fabric discovery (subnet 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 select which fabrics to discover.
NOTE
Switches might appear in your subnet scan even after you unplug the Ethernet cables of those
switches.
Running a subnet scan
1. Select Discovery > Subnet scan.
The Subnet scan dialog box displays (see Figure 41).
NOTE
Subnet scan is only available for IPv4-formatted addresses: IPv6-formatted addresses are not
supported for this feature.
