Guys

I would like your ideas as to why I am getting dar0 and dar1 showing up please. I have had to re-install AIX on a box and now fget_config -Av now shows:

----dar0---

dac0 ACTIVE dacNONE ACTIVE

-----dar1----

dac1 ACTIVE dacNONE ACTIVE

Both HBAs are defined on the storage and are included in an effective zone.

Another thing is that I attached 8 SAN disks and only the first disk is showing up in aix and the same disk shows up on both dac0 and dac1. When I removed the first disk on the SAN, none of the other disks was picked up by AIX.

There were changes on the SAN switch but both switches now have a similar configuration and none of the other (7) lpars is displaying this problem. I have removed the fibre adapters (rmdev –dl dar0, dar1, fcs0, fcs1, scsi0, scsi1 etc) but the issue would not go away.

Another thing is that the install does not seem to be recognising the router as a DS4800 one. For example, on a box that is working correctly, I would get the following:

lsdev | grep dar
dar0 Available 1815 DS4800 Disk Array Router
en0 Available 06-08 Standard Ethernet Network Interface
en1 Available 07-08 Standard Ethernet Network Interface
en2 Available 08-08 Standard Ethernet Network Interface
en3 Available 0A-08 Standard Ethernet Network Interface

However, on the new box with problems I get the following even though (I believe that the other boxes were installed from the same CD set- AIX 5.3.0)

lsdev | grep dar
dar0 Available fcparray Disk Array Router
dar1 Available fcparray Disk Array Router
en0 Available 04-08 Standard Ethernet Network Interface
en1 Available 04-09 Standard Ethernet Network Interface
en2 Available 07-08 Standard Ethernet Network Interface
en3 Available 07-09 Standard Ethernet Network Interface

Notice that the other box clearly indicates that this is a “DS4800 Disk Array Router”.

The following are the effective switch configurations:
