The principle differences between FC and TCP/IP access are:
•A TCP/IP host with an HBA installed does not need to connect to a fabric to manage other hosts.
•A TCP/IP management host can manage all of the HBAs in a remote host, not just the ones connected to the same fabric. FC can only manage HBAs connected to the same fabric.
•You can manage many more hosts since TCP/IP access is not constrained by the boundaries of a fabric or zoning.
•True board status (e.g. link down) is available since the FC path is not necessary to send a status request to the remote host.
•HBA security in a TCP/IP environment is much more important since many more hosts are available for management and TCP/IP access is not affected by fabrics or zoning.
•Discovery of hosts in a TCP/IP environment is not automatic like FC discovery.
Adding a Single Host
The HBAnyware utility enables you to specify a single TCP/IP host to manage. If the host is successfully discovered, it is added to the static list of hosts. If it has not been discovered over FC, the host and its HBAs are added to the
To add a single host:
1. From the Discovery menu, select TCP/IP>Add Host. The Add Remote Host dialog box appears.
Figure 10: Add Remote Host dialog box
2.Enter the name or the IP address of the host to be added. Entering the IP address is the best way to add a new host.
Note: Using the IP address to identify the host avoids name resolution issues.
3. Click OK. You will receive a message indicating if the new host was successfully added.
Adding a Range of Hosts
You can find the TCP/IP accessed manageable hosts by searching a range of IP addresses using the Add Range of IP Hosts dialog box. The Add Range of IP Hosts dialog box enables you to build the initial list of TCP/IP accessed manageable hosts.
