Disk mirrors in LVM2 or device-mapper?

[Brian Long <brilong cisco com>]

Hello,

I understand device-mapper in RHEL 4 supports a "mirror" target to
support LVM2's pvmove command.  Can that same functionality be used to
create a full-time software mirror?  Or is the fairly new LVM2 mirroring
functionality supposed to be used (obviously this is not in RHEL 4 yet).

Also, what's the deal with the qlogic driver in RHEL 4 not supporting
the scsl-qlascan command?  They removed the /proc interface before
replacing it with the /sys interface?  Jeez, that's a move backwards
from RHEL 3.

Thanks for any info.
