SUMMARY: new to SAN -- need some direction

Well, here I go again, replying to myself.

Turns out everything is working correctly.  It was a matter of getting the
correct controller on my end (c11/c12/c13/c14) and matching that up with
the correct WWN on the other end.

When I re-read the install guide, I decided to just do a cfgadm -c
configure on every WWN listed in the cfgadm -al output.

Four of them matched, and I got my luns partitioned and newfs'd.

Subject: new to SAN -- need some direction


So we've got an Enterprise E3500 running Solaris 8 04/01 with the latest
recommended patch cluster (as of last week).

I've got a brandy-nifty new NetApp FAS960c with SAN functionality.  It's
connected to two Brocade SilkWorm 8 port switches.

I've got two Sun SBus dual-port HBAs in my E3500 (both are the QLOGIC
cards).  They are likewise connected to the Brocade switches.

I've installed the SFS 4.4 software packages and patches, and I rebooted
the machine.

I'm trying to follow the SFS install and config guides, but I'm getting a
bit lost.  I've never dealt with a SAN before.

I run cfgadm -al and get this (I removed everything but the FC stuff):
c11                            fc-fabric    connected    unconfigured unknown
c11::210100e08b299781          unknown      connected    unconfigured unknown

c14                            fc-fabric    connected    unconfigured unknown
c14::210000e08b07ecbb          unknown      connected    unconfigured unknown
c14::500a098383511e35          disk         connected    unconfigured unknown
c14::500a098383f11ddf          disk         connected    unconfigured unknown
c14::500a098c83511e35          disk         connected    unconfigured unknown
c14::500a098c83f11ddf          disk         connected    unconfigured unknown

Now, the 500xxx stuff is confirmed to be the WWNs on the NetApp.  I'm not
sure what the 210xxx stuff is -- are those the WWNs of my HBAs?  Why are
they unknown?

More importantly, if they *aren't* the WWNs of my HBAs, then how do I get
the WWNs so that I can configure the NetApp LUNs correctly?

Secondly, I've tried to configure the LUNs using cfgadm -c configure, but
I get this:
[14:05:18]root@oracle1.stage:/root$ cfgadm -c configure c11::500a098183511e35
cfgadm: Library error: failed to create device node: 500a098183511e35: Invalid argument

Could this be because the LUNs don't have the correct WWNs associated with
them, or is there perhaps another issue?

Any help with this would be greatly appreciated -- it's all new to me.

Thanks very much,
-Adam
