1. The following figure shows the error information.

2: Cause
Others mistakenly select the target VNFD as 3 nodes during the 5-node patch check. As a result, the VDU of the CSP_D type in the 5-node cluster is updated to the 3-node cluster.
An error is reported when the LCM performs integrity check.
3. Problem confirmation:
3.1 On the LCM page, choose Package Management > VNFD. Search for the 3-node VNFD of the target. Select and export
3.2 Decompress the exported VNFD file, go to the plans directory, search for the plan file in the directory, and check which plan files contain the following fields:
CSP_D:

The search result is similar to the following:

4. Workaround:
If the target VNFD is not used on the LCM, delete the VNFD on the LCM, upload the VNFD again, and perform the pre-upgrade check again.
If the target VNFD is in use, perform the following operations:
4.1 Log in to the active and standby LCM nodes. Go to the plan directory where the target VNFD is located.
4.2 Find the name of the faulty plan file in step 3.2.
4.3 Delete the faulty plan.
4.5 Synchronously Modifying the LCM File on the Standby Node
4.6 Restart the services on the two LCM nodes.
