Comment 1 Elad 2014-03-27 17:05:07 UTC

LUN change is detected by engine.
TCMS run was executed: 
https://tcms.engineering.redhat.com/run/124090/

Verified according to the following steps:


-Install RHEL on host (make sure the host is not exposed to any devices via FC)
-Once host has RHEL OS installed, Expose a 20G LUN to it from the storage server via FC
-Create a FC storage domain resides on a 20G physical volume
-Activate the domain
-Issue SAN copy from storage server side - copy the data from the 20G LUN to a new 25G LUN
-Connect the new LUN (25G) to the host (LUN masking) and remove the original LUN (20G)
-Reboot the host so the FC connected devices will be rescanned
-Activate the storage domain
-Under 'Storage domains' tab, pick the relevant domain and click on 'Edit'.

LUN ID changed to the new one

====
Verified using RHEV3.3.2 - IS35
