Use "devfsadm -C" to remove old links. Also, make sure the array has LUNs created, mounted, and exported.

Lots of reasons why you cant see the T3 from the server.

How is the T3 connected and to what is it connected?

Do you go via a switch or is it direct attached?

If it is via a switch, what is the port configuration set to?

Also, if it is via a switch, do you have a mixture of other devices in the zone?

Is it a T300 or a T3B?

Do you have mpxio turned on on the server?

Do a sys list or .sys list depending on the T3 and post that.

I always do a devfsadm -v -C when I run that command as it shows you what it is doing.

ok, after devfsadm -C, nothing changed.

Still at the server side I see old T3s which we had re-configured to another server and there all is fine. So I normally know the steps.

The new configured T3 (new as it was complete rebuild by SUN) is setup for 2 servers.

On Server A all is find with same commands, nothing special.

On Server B I cannot get the new T3 connected as the old ones still there ?. Old T3 connection are unconfigured but devfsadm -C does not clean it.

Dont know how to clean old T3 connections.

We are not using a switch, mpxio is enabled.

t3be4:/:<2>sys list

controller : 2.0

blocksize : 32k

cache : auto

mirror : auto

mp_support : mpxio

naca: off

rd_ahead: on

recon_rate : med

sys memsize: 128 MBytes

cache memsize: 1024 MBytes

enable_volslice: on

fc_topology: auto

fc_speed: 1Gb

disk_scrubber: on

ondg: befit

all is based on SOLARIS 8, and we cannot change to 9 or 10.

I have to ask what the T3 is configured as.

It is a single T3 or it is two T3's configured at a partner pair? If you have two T3's connected by those serial like cables on the back, you cant share the two T3's between two hosts. Only one controller is ever active.

If there is a cable between the two T3s, remove it and this will make both the T3's available to the two hosts.

If it is a single T3, how can you share it between multiple hosts? It only has one fibre connection.

As you have already had T3's connected to your host, you must have the SAN foundation software on your server.

Can you do a luxadm probe on the host and also do a port list on the T3.
