AMIR(4) BSD Programmer's Manual AMIR(4)NAMEamir - AMI MegaRAID logical disk driver
SYNOPSIS
amir* at amic? drive ?
amir1 at amic1 drive 0
DESCRIPTION
The amir driver provides access to individual logical disks on AMI
MegaRAID controllers. The amir driver takes care of requesting resources
from the amic driver; sorting and queueing requests when resources are
not available; starting read or write operations; marking buffers com-
plete when read or write operations complete; along with reading and
writing of disk labels.
The disk should be labeled with disksetup(8) before use.
The disk may optionally contain a DOS fdisk label, and portions of the
disk may be reserved for other operating systems.
USE AS BOOT DEVICE
In order to boot the system from a amir device use disksetup(8) to in-
stall BIOS boot blocks. Currently boot(8) can not detect that the boot
device is a amir device and will assume that the boot device is an sd(4)
attached SCSI disk. To work around this an entry must either be placed in
/etc/boot.default or entered at the ``boot:'' prompt. The following is
an example of this:
-rootdev amir0
FILES
/dev/amir[0-1][a-h] block files
/dev/ramir[0-1][a-h] raw files
/boot Second stage boot
/etc/boot.define Default boot commands
