18.4 RAID1 - Mirroring

[Wojciech Łukowicz]

Hello,
recently I have been trying to make a mirror on two 9.2GB SCSI drives.
I followed the 18.4 chapter from handbook but unfortunately it didn't 
work, when I was trying to insert second disk to mirror, "Provider da0 
too small." appeared.
It was strange because those hdds are theoretically equal in size.
I googled little bit and it turned out that checking disks size with
/usr/sbin/diskinfo -v /dev/da[01]
is important - disks must be either completely equal or the second must 
be a little bit smaller.
In my case the solution was to change SCSI ID using jumpers.
I think that adding information about diskinfo would be really helpful 
for people.
