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.
