Hi

You can use alternated PV links for each PV link if you can't use SecurePath. But SecurePath has more advantages than alternated PV links

you can look at man page of pvcreate,

There is a section from man

When a pv_path refers to one of the physical volumes already in the volume group by a different pv_path name to indicate the use of a different controller, this new path becomes an alternate link to the physical volume. When two paths that reference the same disk are provided in the pv_path list, the order of the paths is important. The first path becomes the "primary link" to the physical volume, the second becomes an "alternate link" to the physical volume. The primary link is the path used to access the physical volume unless the primary link becomes unavailable in which case LVM automatically switches to the alternate link to access the physical volume. Currently LVM supports a maximum of 8 paths to a physical volume (7 alternates and one primary).

I hope it helps to your problem
