Solaris Information On WWN

Recently I had some messages on a T5-2 hypervisor and I needed to find out exactly what it is complaining about.

Messages looked like this:

fctl: [ID 517869 kern.warning] WARNING: fp(5)::GPN_ID for D_ID=160003 failed
fctl: [ID 517869 kern.warning] WARNING: fp(5)::N_x Port with D_ID=160003, PWWN=23220002ac0012b4 disappeared from fabric

fctl: [ID 517869 kern.warning] WARNING: fp(5)::N_x Port with D_ID=160003, PWWN=23220002ac0012b4 reappeared in fabric

First let's check the adapters and ports.

Let's check which ports are connected.

# luxadm -e port
/devices/pci@340/pci@1/pci@0/pci@4/SUNW,qlc@0/fp@0,0:devctl        CONNECTED
/devices/pci@340/pci@1/pci@0/pci@5/SUNW,qlc@0/fp@0,0:devctl        CONNECTED
/devices/pci@340/pci@1/pci@0/pci@4/SUNW,qlc@0,1/fp@0,0:devctl      NOT CONNECTED
/devices/pci@340/pci@1/pci@0/pci@5/SUNW,qlc@0,1/fp@0,0:devctl      NOT CONNECTED

Now let's find devices on the above two connected ports. You should be able to see the original warning WWN's listed here.

You can try and see if the device is listed here. In my case it was not so it appears that we are not using this device but maybe the switch still have us zoned for the device.

# luxadm probe
No Network Array enclosures found in /dev/es

Found Fibre Channel device(s):
  Node WWN:20000024ff57d64d  Device Type:Disk device
    Logical Path:/dev/rdsk/c0t600144F086479F15000053DA5A03000Ad0s2
[..]

# luxadm probe | grep 2ac0012b4  <-- Not found so remote?

We probably did not need all steps above to get to the next command but I am listing everything since it depends on the situation and what you are tracing.

Here I can see the relevant WWN is a 3PAR SAN and in my case I knew I am not using 3PAR any longer so I can check if this is a zoning issue.
