HDD with status Avail, cannot add to spare

Hi All,

I have a MSA P2000. I have the problem when I want to add a new hard drive to the Global spare. When I set through the web gui, had the status of a hard drive into a Global Spare. but there is not a minute, the hard drive returns the Avail status. I also tried adding it to a dedicated spare, but the result is the same. I have also tried via CLI, the result is same as well. Is there a system or hardware malfunction here?

I attach an error log.

Thanks you
