[dm-devel] md_component_detection = 1

[shahid shaikh]

Hello Chris,

    I have written a sample psuedo driver which is basically consolidating
multiple paths to LUNs.
So I need prevent SCSI devices from scanning.

I gone thro' lvm.conf and found out that md is doing the similar thing by
setting following value in lvm.conf

         md_component_detection = 1
this parameter, if set, prevents scanning of all the SCSI devices
contributed in the creation of md.

So is there any parameter in LVM2 or device mapper, setting or clearing
which can prevent scanning of SCSI devices used for my psuedo driver.
Obviously other than filtering it out.

Thanks and Regards,
Shahid Shaikh.
