need help with scsi hardware raid.

Hi folks,
i have installed freebsd 4.7 on a compaq proliant server, it has
hardware scsi raid, has 3 scsi hard drives. installed freebsd on
/dev/da0 i want to mirroe this drive on /dev/da1 and use /dev/da2 as
an extra drive.

i looked around the freebsd handbook storage section: 12.4.2 but was
not very helpful. looked around news groups and google a bit.

dmesg picks up the three drives, adaptec scsi adapter, dmesg | grep -i
raid doesnt show any thing. ( may be this is the problem?)

can some one post a howto in going about hardware scsi raid? or point
to some link, i would appreciate it.

thanks,
g.

As Matt says, for hardware you usually have to set it up outside of the OS.

Now, from memory Compaq has a utility on their setup CD to do all this,
and I think there is something in the built in BIOS utils. Use that to
configure the RAID as you wish.
