[CentOS] lsraid on centos 4.2

On older systems redhat 9 there was a command lsraid....
I have a centos 4.2 system that does not have that command.
What is the new command that is equivalent to "lsraid -a /dev/md0"?

Or is there a package that does not get loaded by default?
Lsraid is not on my system.

THanks,
