Preparing source and destination arrays for migration

Contributors Download PDF of this page

To prepare for the FLI 7-mode to ONTAP migration, verify the host and source LUN paths and other details.

Steps
  1. In ONTAP, change to advanced privilege level.

    cluster::> set adv
    
    Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel.

    cluster::*>
  2. Verify that the source array can be seen on the destination controller.

    cluster::*> storage array show

    Warning: Configuration errors were detected.  Use 'storage errors show' for detailed information.
  3. View details on any storage errors listed. Some errors might require action before proceeding. However, the errors shown in the following example, “This device is an ONTAP® LUN.” can be safely ignored.

    Note

    The error message “This device is an ONTAP\(R\) LUN.” is caused because FLI relies on FlexArray technology which doesn’t support virtualizing ONTAP or ONTAP targets. FLI is able to import the LUNs, however, FlexArray doesn’t support virtualizing them.

  9. Create the target LUN. The LUN create command detects the size and alignment based on partition offset and creates the LUN accordingly with the foreign-disk argument

  14. Map the test LUN to the test igroup.

    cluster::*> lun map -vserver fli_72C -path /vol/flivol/72Clun1 -igroup 72C_g1
    
    cluster::*> lun mapping show -vserver fli_72C

  15. Offline the test LUN.

    cluster::*> lun offline -vserver fli_72C -path /vol/flivol/72Clun1
    
    Warning: This command will take LUN "/vol/flivol/72Clun1" in Vserver "fli_72C" offline.
