To prepare for the FLI 7-mode to ONTAP migration, verify the host and source LUN paths and other details.
Steps
-
In ONTAP, change to
advancedprivilege level.cluster::> set adv Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel. Do you want to continue? {y|n}: y cluster::*> -
Verify that the source array can be seen on the destination controller.

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.
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.
