Why do I have this names in my redhat 5 server?

[root@sanserver ~]# lsmod | grep multipath
 dm_multipath           58969  2 dm_round_robin
 scsi_dh                42561  1 dm_multipath **#Module name with _**
 dm_mod                103569  28 dm_multipath,dm_raid45,dm_snapshot,dm_zero,dm_mirror,dm_log

 [root@sanserver ~]# modinfo dm_multipath
 filename:       /lib/modules/2.6.18-371.3.1.el5xen/kernel/drivers/md/dm-multipath.ko **#name with -**

I got two differents names, but there is not alias, one is dm-multipath and second dm_multipath

You are looking at two different names. The module is called dm_multipath, and the file that it is loaded from is called dm-multipath.ko. These names need not match — the module would still be loadable (via insmod, at least) if you renamed it to example.ko, but the module would still internally be called dm_multipath.
