Hi Steven,

Thank you for the reminder and for fixing this bug.
This was indeed not thoroughly considered.

However, I am curious: if the HBA is removed, implying that the 
storage would become unusable, might the system encounter an 
I/O hang or shutdown, potentially preventing its detection? 
Perhaps it's a theoretical issue that would not manifest 
in a real-world situation?

Thanks
Peter
