there should be messages in data mover log as to why the rescan is failing
I would sugest to open a service request

I have ran into similar issues when trying to manage Celerra's backend storage manually. I don't know of a fix other than to use the Celerra's builtin storage configuration script. I think the script is in /nas/sbin/clarion_setup ( I am assuming the backend is a Clariion).

did you delete the old dvols using "nas_disk -d -perm" ?
do they still show up in "nas_disk -l" ?
if yes does it show up in use ?

Hi All
Thanks for your help .i have solved it . I changed the LUN ID of the new LUN i created this might have caused the problem.I deleted that lun created a new one with 1.5 Tera changed only the host id added to the Cellera storage group rescanned it works fine .
Thanku
