Not sure what you mean, as I don't use mdadm...  There is a BIOS level 
utility you access at boot time to add and remove drives from the array, 
which you can do with a failed drive after it has cooled off and started 
working, if you only have one or two (after the first fails, the hot 
spare replaces it, when the second fails, the RAID5 still works but in 
degraded mode - it's when the third fails that problems set in, because 
the other two have been marked bad and stay that way until you release 
them and reassign them).  It may be possible to do that with the tw_cli 
utility, but I wouldn't know how as I never needed to do that to a 
running system.  Since it was shut away in a closet (hence the bad 
ventilation) and I didn't have a mailer daemon running for it to send 
failure notices through, I never knew it was bad until it was totally 
borked.  Once put into a cooler environment, I've never had another 
problem with it.
