Others have suggested the /etc/mdmadm.conf file, which may help. 
However, if you are running a 2.4.x kernel you may have better luck with
and /etc/raidtab config file.  Recent experiences here show that the
2.4.x kernel series has a startup script for /etc/raidtab but not
/etc/mdmadm.conf.  The 2.4.x kernels use older commands that are part of
the raidtools package.  Newer 2.6.x kernels use newer commands like
mdadm.  Both can be used the manipulate software RAID arrays, but again
I don't think 2.4.x kernels include a startup scripts for mdmadm and the
associated configuration file.
