Thanks guys. This reassures my logic and hopefully the
customer will go with 4 drives instead of two.
But as stated they probably could go with just 2 drives but lose
the true effect of the stripping and increased redundancy.

mlxctl
MLXCTL(8) BSD System Manager's Manual MLXCTL(8)
NAME
mlxctl -- Mylex DAC960 family management utility
SYNOPSIS
mlxctl [-f dev] [-v] [-a] status [drive] [...]
mlxctl [-f dev] [-a] detach [drive] [...]
mlxctl [-f dev] [-a] check [drive] [...]
mlxctl [-f dev] rebuild channel:target
mlxctl [-f dev] cstatus
mlxctl [-f dev] rescan
mlxctl [-f dev] config
DESCRIPTION
The mlxctl utility performs status monitoring and management functions for Mylex DAC960 RAID controllers and attached devices.
The following options are available:
-a Apply the action to all drives attached to the controller.
-f dev Specify the control device to use. The default is /dev/mlx0.
-v Increased verbosity.
The following commands are available:
cstatus Display the controller's current status.
status Display the status of the specified drives. This command returns 0 if all drives tested are online, 1 if one or more drives are
critical and 2 if one or more are offline.
rescan Re-scan the logical drive table, and attach or detach devices from the system as necessary.
detach Detach the specified drives. Drives must be unmounted and unopened for this command to succeed.
check Initiate a consistency check and repair pass on a drive that provides redundancy (e.g., RAID1 or RAID5). This command returns imme-
diately. The status command can be used to monitor the progress of the check.
rebuild Rebuild onto the specified physical drive. Note that there can be only one running rebuild operation per controller at any given
time. This command returns immediately. The cstatus command can be used to monitor the progress of the rebuild.
config Write the current system drive configuration to stdout.
EXAMPLES
Display the status of drive ld3 attached to the controller mlx1:
mlxctl -f /dev/mlx1 -v status ld3
SEE ALSO
ld(4), mlx(4)
HISTORY
The mlxctl command first appeared in NetBSD 1.5.3, and was based on the mlxcontrol utility found in FreeBSD.

Modifying drive configuration is not yet supported.
