On my VNX I have trespass luns, and when I try to move them back to their orignal SP, they will not move.  I use the step below, however I do not know how to run the CLI.  Because my management console is on a Window machine. 

Restoring LUNs using Unisphere:

1.The "Restore SP" button can be found under the Storage section in the right-hand task pane under "File Storage" > Restore LUN Ownership for File.

 

2.If the "Restore SP" button is not seen, but the "Trespassed LUNs Status" shows trespassed LUNs, go to SYSTEM > HARDWARE > HARDWARE FOR FILE > Click on the "wrench" tools symbol in the upper right-hand side of the screen across from the Inventory heading, and select "Invalidate Cache and Refresh" from the drop-down menu.

a)   Return to the STORAGE > Restore LUN Ownership for File location, and select "Restore SP" if presented.

b)   If not presented, you will need to use the CLI method to restore trespassed LUNs, as shown below.

  Restoring LUNs using commandline:  

Alternatively, Users can connect to the Control Station via Putty, and an SSH session, login as nasadmin, then su to root, and run the following command to failback VNX File LUNs:

1.# nas_storage -l  -->Use this output to verify storage system ID number, which is then used in the -failback commandid   acl    name           serial_number

1    0      FNM00104600114 FNM00104600114

2.# nas_storage -failback id=1id       = 1

serial_number        = FNM00104600114

name     = FNM00104600114

acl      = 0

done

3.Verify that VNX File LUNs are no longer trespassed using UNISPHERE > SYSTEM > MONITORING > Trespassed LUNS Status or # nas_storage -c -a
