Before transitioning a SAN environment, you must understand what configurations are supported for SAN transition, create SAN LIFs on the SVM, and prepare the SAN hosts for transition.
Preparing SAN hosts for transition
Before transitioning a SAN environment, you must perform some manual steps to prepare the SAN hosts for transition.
Configuring zones by using the FC zone plan
Before transitioning a SAN FC environment, you must configure zones by using the FC zone planner to group the initiator hosts and targets.
Creating SAN LIFs before transition
Because FC and iSCSI LIFs are not transitioned by the 7-Mode Transition Tool, you must create these LIFs on the SVMs before transition. You must configure SAN LIFs on both the nodes that own the LUN and the node's HA partner.
Space considerations when transitioning SAN volumes
You must ensure that sufficient space is available in the volumes during transition. In addition to the space required for storing data and Snapshot copies, the transition process also requires 1 MB of space per LUN for updating certain filesystem metadata.
