VMWare "no coredump target has been configured. Host coredumps cannot be saved"

[cah]

After storage migration, we started seeing the warning "no coredump target has been configured. Host coredumps cannot be saved" on laxv1bvse50a/b/c. I didn't get a chance to check until today.

It was caused by the missing SAN boot disk after storage migration from the old array to the new array.
The steps to fix it and clear the warning are as follow. The new SAN boot disk will be used for the core dumps.
