the error says the root disks of Celerra have trespassed to peer SP, you may have to do a health check before failing it back. such as, if there are any faulty drives or SPS on the backend.
you can failback the LUNs to the default owner using the command :

Hi vanitha,
Please find the below,
[nasadmin@MASCRPPIPST2 ~]$ nas_storage -c -a
Discovering storage (may take several minutes)
Error 5017: storage health check failed
SL7F9111100024 SPA is failed over
SL7F9111100024 root_disk is failed over
SL7F9111100024 root_ldisk is failed over

nas_storage -failback command brings the storage back in to its normal operation. Here it assigns all the disks to its default owner.
Are you getting this trespass error now a days also ?

Hi Sameer,
I ran the following commands in control station as nasadmin
#/nas/bin/nas_storage -failback id=1
#/nas/bin/nas_storage -c -a
Now, The Error was Gone

Hi,
if root_disks are being trespassed frequently, I would suggest you to gather spcollects and have a Clariion support engineer to analyze them.
