Goal

How to change the hostname of an IB switch that is running 2.1.x
 

Solution

Original name  "infiniband36p-bur09-a-sp"  new name "newname-bur09-a-sp"

1)    -> set hostname=newname-bur09-a-sp   <<<New name specified here
          Set 'hostname' to 'newname-bur09-a-sp'

2)     -> set system_identifier=newname-bur09-a-sp.us.oracle.com
           Set 'system_identifier' to 'newname-bur09-a-sp.us.oracle.com'

3)     -> reset /SP  (Proper way to reboot an IB switch)
            Are you sure you want to reset /SP (y/n)?

The system is going down for reboot NOW!
After switch comes back up we can see the system prompt and the ibswitches output reflect the new name.
