The following table shows the supported features available for IPFC.
Table 6-1 IPFC (NFS/NAS and SNDR)
The following restrictions apply:
IPFC is not supported on Oracle 1 Gbit switches.
Network cards using IPFC cannot be used as routers. The /etc/notrouter file must be present on the host.
Any standard network commands can be used after IPFC is attached. These commands (telnet, ping, or ftp) are used in this environment in the same way as in an Ethernet setup.
This section explains how to configure the desired host system for IPFC. It includes the procedures to determine the port instance and to plumb an IPFC instance.
You need this information to perform the calculation in Determining Fibre Channel Adapter Port Instances.
The examples in this procedure 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.
Note - Determine the correct entry by finding the hardware path described in your server hardware manual.
Note - The following method of deriving the device path of an HBA from its physical location in server might not work for all Oracle's Sun server hardware.
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.
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.
The number 11 converts to “b” in hexadecimal.
The following table shows the elements of the device path for a PCI single FC network adapter device that has the following path:
"/pci@b,2000/SUNW,qlc@2/fp@0,0" 7 "fp"
Use the ifconfig interface-number plumb command. In this example, the value of interface-number is fcip7.
# ifconfig fcip7 plumb
If the command is successful, a message appears on both the console and in the messages file. For example:
Sep 13 15:52:30 bytownite ip: ip: joining multicasts failed (7) on fcip0 - will use link layer brocasts for multicast
Each FP instance on the system has an entry in /dev/fc. If HBAs have been removed, some stale links might exist. Use this procedure to load and plumb IPFC.
# luxadm -e dump_map /dev/fc/fp0 Pos Port_ID Hard_Addr Port WWN Node WWN Type 0 610100 0 210000e08b049f53 200000e08b049f53 0x1f (Unknown Type) 1 620d02 0 210000e08b02c32a 200000e08b02c32a 0x1f (Unknown Type) 2 620f00 0 210000e08b03eb4b 200000e08b03eb4b 0x1f (Unknown Type) 3 620e00 0 210100e08b220713 200100e08b220713 0x1f (Unknown Type,Host Bus Adapter) # luxadm -e dump_map /dev/fc/fp1 No FC devices found. - /dev/fc/fp1
In the example for this procedure, the destination HBAs have port IDs 610100 and 620d02. The originating HBA’s port ID is 620e00.
# ls -l /dev/fc/fp originating-hba-link
In the following example, 0 is the number for the originating-hba-link:
# ls -l /dev/fc/fp 0 lrwxrwxrwx 1 root root 51 Sep 4 08:23 /dev/fc/fp0 -> ../../devices/pci@8,600000/SUNW,qlc@1/fp@0,0:devctl
You must remove the leading ../../devices from the path name output. For example:
# grep pci@8,600000/SUNW,qlc@1/fp@0,0 /etc/path_to_inst "/pci@8,600000/SUNW,qlc@1/fp@0,0" 0 "fp"
The instance number precedes “fp” in the output. In the following example output, the instance number is 0.
"/pci@8,600000/SUNW,qlc@1/fp@0,0" 0 "fp"
In this example, the instance is 0.
# ifconfig fcip 0 plumb
