Dell 2950 Perc 5/i RAID Controller and FreeBSD 6.1 Question

[Brian A. Seklecki]

It would be very very useful if you provided dmesg(8), bsdlabel(8), and 
fdisk(8) outputs to illustrate the problem.

For each RAID group you assemble in the BIOS/CMOS utility, you should see 
a seaparate mfid[0-9] phyiscal device.  Once properly partitioned, they 
should each contain "s1" slice -- for some reason we number disks from 0 
but slices from 1 (possibily because the BIOS does)

Then each physical slice can be BSD labeled'd with [a-z]
