How to restore or assign old fsid incase of FST disk has replaced due to faulty disk

Dear Experts,

If any disk of FST has go bad and it will replace with new one. The old fsid of disk was 14 and group is default.1.
So, In this case if we will re-register or add those new disk with same fsid i.e. 14 in same group will possible? Or it will register with new fsid.

If it will possible to assign old fsid to new disk, how we do this?

(As per my knowledge, when new disk has register or add in eos then old fsid has mapped to new fsid and old fsid is not used. )

Suggest.
