NAME
ips —
IBM SATA/SCSI ServeRAID
controller
SYNOPSIS
ips* at pci?
DESCRIPTION
The ips driver provides support for IBM
ServeRAID controllers, including:
- ServeRAID 3H/3HB/3L
- ServeRAID 4H/4L/4Lx/4M/4Mx
- ServeRAID 5i/5i II
- ServeRAID 6i/6M
- ServeRAID 7k/7M/7t
Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers. All RAID configuration is done through the bootable IBM ServeRAID Support CD; a CD image is freely available at the IBM website.
RAID management is done through the bio(4) device with the bioctl(8) command. Logical disk status is exposed under the hw.sensors sysctl(8) and can be monitored using sensorsd(8).

HISTORY
The ips driver first appeared in
OpenBSD 4.1.
AUTHORS
The ips driver was written by

CAVEATS
Due to bioctl(8) limitations the ips driver
associates all unused and hot spare drives with the first volume but the
drives can be used for rebuilding any degraded volume.
