Restructure the cdsmcp folder to separate operator guidance, reusable templates, and runtime artifacts into clearer top-level areas. Move the VMware migration guide and run learnings into docs/, move vmw.yaml into templates/, move the existing log into artifacts/logs/, replace the old index file with a README, and split the former monolithic guide into focused documents for VMware MigrateOps workflow, VM lookup and FC/disk assignment, and CMC install reference. Update internal references so the reorganized layout remains coherent without changing the underlying operational guidance.

ATVM Local Data Disk CDC Migration Report
|
|
|
|
Host: atvm-codextest-vm
|
|
Date: 03-18-2026
|
|
VM IP during run: 192.168.3.191
|
|
Project: Skidamarink
|
|
Guest OS: Oracle Linux Server 9.7
|
|
|
|
Summary
|
|
- Powered on the VM and reinstalled CMC for Linux.
|
|
- Used /dev/sdb as the source data disk and /dev/sdc as the destination data disk.
|
|
- Created an ext4 filesystem on /dev/sdb and mounted it at /mnt/disk1.
|
|
- Created a local migration session for /dev/sdb -> /dev/sdc.
|
|
- Wrote about 1 GiB of data to /mnt/disk1/aw.dat with fio while the session was active.
|
|
- Waited for the session to resynchronize and return to TRACKING with remaining data at 0.
|
|
- Performed cutover, then final cutover.
|
|
- Unmounted the source mount after final cutover, deleted the session, mounted the destination disk at /mnt/destination, and verified the migrated file.
|

Source File Verification
|
|
- Source path: /mnt/disk1/aw.dat
|
|
- SHA-256: b695f7743705a16ef6c346d7d3a962d3608d10af4eae12e7474e2224efc0fe47
|
|
|
|
Key Session State
|
|
- Session created successfully.
|
|
- Initial file write produced changed data on the session.
|
|
- Explicit sync completed and the session returned to TRACKING with remaining = 0.
|
|
- Session then entered cutover/cmotion successfully.
|
|
|
|

|
|
|
|
Post-Cutover Handling
|
|
- /mnt/disk1 unmounted before session deletion.
|
|
- Migration session deleted successfully.
|
|
- No migration sessions remained after deletion.
|
|
|
|
Destination Verification
|
|
- Destination disk mounted at /mnt/destination from /dev/sdc
|
|
- Destination file: /mnt/destination/aw.dat
|
|
- Destination SHA-256: b695f7743705a16ef6c346d7d3a962d3608d10af4eae12e7474e2224efc0fe47
|
|
|
|
Verification Result
|
|
- Source and destination SHA-256 values match exactly.
|
|
- Data verification passed.
|
|
|
|
Final Guest Disk State
|
|
- /dev/sdb present and not mounted
|
|
- /dev/sdc mounted at /mnt/destination as ext4
|
|
|
|
Notes
|
|
- The session remained in TRACKING with changed data after the fio write until an explicit auto-resync interval and sync were applied.
|
|
- Cutover succeeded first; final cutover had to wait until the session transitioned from TRACKING to STANDING_IN.
