Any standard network commands can be used after IPFC is attached. These commands
(telnet, ping,orftp ) are used in this environment in the same way as in an Ethernet setup.
Determining Fibre Channel Adapter Port Instances
This section explains how to congure the desired host system for IPFC. It includes the
procedures to determine the port instance and to plumb an IPFC instance.

To Determine Port Instances
Determine the HBA PCI adapter slot and the I/O board PCI slot.
You need this information to perform the calculation in “Determining Fibre Channel Adapter
Port Instances” on page 60
.
For example, assume you have an array with an HBA card located in PCI adapter slot 5, and the
PCI adapter is in slot 1 of the I/O board.
Determine the instance number.
a. Search for the fp driver binding name in the /etc/path_to_inst le.
Note – Determine the correct entry by nding the hardware path described in your server
hardware manual or Sun System Handbook. The Sun System Handbook is available at
http://sunsolve.sun.com/handbook_pub/.
b. Narrow the search by using the I/O board and slot information from Step 1.
Note – The following method of deriving the Solaris 10 OS device path of an HBA from its
physical location in server might not work for all Sun server hardware.
i. Multiply the PCI adapter slot number by the number of adapter ports.
For example, if the HBA has two ports, multiply by 2. Using the array with an HBA in the
PCI adapter slot 5, multiply 5 by 2 to get 10.
ii. Add the PCI adapter I/O board slot number to the number derived in Step i.
Using an HBA in PCI adapter slot 5 and PCI slot 1 of the I/O board, add 1 to 10 for a sum
of 11.
iii. Convert the number derived in Step ii to hexadecimal.
The number 11 converts to “b” in hexadecimal.
