hi,

what are the steps to detect and configure a new attached lun in Solaris 10.
Is there any difference between cfgadm and luxadm command ?

There are a lot of different scenarios. Are you using Powerpath and/or Veritas Storage Foundation (vxfs)? Most companies have varying procedures on how they want new LUNs configured.

Solaris 10 detects the newly zoned luns automatically... it should be visible in below command output at the top with its size information.

 
format

In case it doesn't detects, then you can run below commands on the controllers through which the luns are to be seen.

 
cfgadm -c configure <controller>

Once the luns is seen by the OS, later you can configure the same under powerpath or Veritas.

It is sufficient to run

cfgadm -al

No need to configure controllers.

Normally you don't need to run cfgadm -al unless you're having trouble detecting the new new LUNs. devfsadm -C should be sufficient.
