Hi All,

It is configuring interfaces for lpfc0 and lpfc1. I don't know from where it is plumbing interfaces. Any body have idea the problem.... thanks.

        inet 172.16.31.204 netmask ffffff00 broadcast 172.16.31.255
        ether 0:3:ba:72:69:96
lpfc0: flags=1000862<BROADCAST,NOTRAILERS,RUNNING,MULTICAST,IPv4> mtu 65280 index 5

Make sure you don't have any *lpfc* hostname files in /etc.  Also recheck your /kernel/drv/lpfc.conf file.

These interfaces come from /etc/hostname.lpfc0 and /etc/hostname.lpfc1 files.

u can also do
ifconfig lpfc0 unplumb
and these will be unplumbed.

there are no /etc/hostname.lpfc0 and lpfc1 files in /etc directory. I need to fix this without unplumbing interfaces.

If you are using the HBA's just for SAN storage, then you must edit your /kernel/drv/lpfc.conf file and change the setting for "network-on=1;" to "network-on=0;"   When you installed the HBA, you were asked if you wanted to configure networking, which meant LAN networking, and this created the interfaces for you because you answered yes.

You have to unplumb the interfaces to get rid of them by doing:

ifconfig lpfc0 down unplumb
ifconfig lpfc1 down unplumb

Then, after you have edited the lpfc.conf file, you can run the following:

update_drv -f -n lpfc

and it will re-read the config file on the fly without the LAN networking portion of the lpfc kernel module loading.

You need to make sure that a entry in your /etc/hosts file exist that matches the names specified in /etc/hostname.lpfc0 and /etc/hostname.lpfc1.  This is how Solaris assigns IP addresses at boot time, matching /etc/hostname.net_device names to /etc/hosts entires.

When you were installing the driver, did it leave a log of some kind.  You may want to take alook exactly what files it wrote to.  Your answers may be there.
