If your machine is still working at this point then yes it is
simple; you just issue the correct mdadm command to fail the
device(s) out of the RAID array(s).

An operating system running on commodity PC hardware often doesn't
survive this though, not even SATA or SCSI sometimes, so in these
situations all you can do is reboot.  At least it should all boot up
again even if the drive is failed.

Cheers,
Andy
