I would like to install the latest Atape and Atldd device drivers. Is it
necessary
to delete the library definition along with the drive definitions?  Here is
what
support recommended and I would like to hear what others have done.

delete drive definitions
delete library definition
delete drive at AIX level
stop lmcp daemon
delete lmcp0 definition
deinstall/install Atape
deinstall/install Atldd
run cfgmgr
define library definition
define drive definitions
mkdev -l lmcp0
start lmcp daemon
checkin libv libname * status=scratch(errors will be received on vols with
data)
checkin libv libname * status=private(vols received errors from prev step)
