I am currently using only one FI as a single. Three chassis are connected, of which only one has four cables. Chassis No. 2 and No. 3 have two cables.
It also uses external SAN storage over a FI-SAN switch-to-storage connection.
ESXi on the server in chassis 1 shows the following log, and the storage is not connected.

We removed two cables from chassis 1, and since then, the log has disappeared and the storage has been working normally.
It is configured as below in the chassis search policy.
Is there any action we need to take to use 4 cables in chassis 1?
