Additional Information
•
During the installation of the Intel RAID Controller SRCU31 driver, additional tools are copied
into the /etc directory. Before you can use them you have to create a special device file named
/dev/ rsrch by means of “link.” This device file has to be placed on a device of an Intel RAID
Controller SRCU31 host drive.
•
With “RAIDSYNC” from the /etc directory, you can determine the coordinates of an Intel
RAID Controller SRCU31 host drive. Usually the first host drive has the coordinates
c0b0t0d0.
•
A special device file (character device) is /dev/rdsk/c0b0t0d0s0. In this case, /dev/rsrch can be
generated with: ln /dev/rdsk/c0b0t0d0s0 /dev/rsrch.
•
(c0 = HA, b0 = Bus number, t0 = Target ID 0, d0 = LUN 0, s0 = UnixWare partition).
•
All new SCSI devices are automatically recognized and a corresponding special-device-file is
generated.
•
Host drives must be partitioned and a file system/file system(s) must be created. You can do
this with “diskadd cCbBtTdD.”
•
When using Direct Access Devices with exchangeable media (for example, removable hard
disk drives) that are not reserved for the raw service, media has to be inserted either when the
system is booted, or with StorCon (mount/unmount). Otherwise the device will not be
available under UnixWare.
•
The Intel RAID Controller SRCU31 UnixWare driver supports Direct Access Devices (for
example, hard disk drives and removable hard disk drives) as SCSI-raw devices. This is
especially important if you use removable hard disk drives which you want to exchange with
other controllers. How to reserve a device for the SCSI-raw service is described in the
“space.c” file on the Intel RAID Controller SRCU31 BTLD disk (example and documentation).
•
Multi-processor support: The Intel RAID Controller SRCU31 device drivers for
UnixWare 7.1.1 support multi-processor systems.
