Preparing for post-transition ESXi host remediation
After the 7-Mode Transition Tool (7MTT) transition is complete, you must perform various ESXi host remediation tasks. There are several steps you must complete before you can perform those tasks.
For copy-based transitions (CBTs), perform these steps before initiating the Storage Cutover operation in the 7MTT.
For copy-free transitions (CFTs), perform these steps before initiating the Export & Halt 7-Mode Systems operation in the 7MTT.
Generate the 7-Mode to ONTAP LUN mapping file:
For CBTs, run the following command from the Linux host where 7MTT is installed:
transition cbt export lunmap -p project-name -o file_path
transition cbt export lunmap -p SanWorkLoad -o c:/Libraires/Documents/7-to-C-LUN-MAPPING.csv
For CFTs, run the following command from the system where the 7MTT is installed:
transition cft export lunmap -p project-name -s svm-name -o output-file
transition cft export lunmap -p SanWorkLoad -s svm1 -o c:/Libraires/Documents/7-to-C-LUN-MAPPING-svm1.csv
You must run this command for each of your storage virtual machines (SVMs).
Verify that igroup and initiator mappings are present.
7MTT re-creates the same igroup with initiators used in Data ONTAP operating in 7-Mode, and remaps the clustered Data ONTAP LUN to the host.
Verify that zoning is appropriate for the new clustered Data ONTAP target.
If you are doing a copy-free transition (CFT), run
