The local fibre channel card has a WWN. Seeing that would like an ifconfig. You want to do the equivalent of a seeing a remote host's mac address. I only know for sure how to do this with HP-UX.

fcmsutil /dev/td0
fcmsutil /dev/td0 get remote all

The former will show the local WWN, the latter the remote WWN. (Both commands show a bunch more stuff as well.)

The driver is guaranteed to have the information or it won't work. Any reasonable driver will have an ioctl() to suck the data out. Any reasonable OS will have a utility to display it.

But over on a SunOS 5.9 box, I'm not sure how to do it. fcmsutil is not found. I *think* that "prtconf -v" is doing it. It is definately displaying what looks like a WWN, but I don't see any docs confirming this.

[edit]
Upon further review, prtconf -v is working. It displays the data a second time and here it is labelled "node-wwn".

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       512 MB

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.
