I.6 Further Information
ƒ
During the installation of the ICP driver, additional tools are copied into the /etc direc-
tory. Before you can use them you have to create a special device file named /dev/rgdth
by means of "link"; this device file has to be placed on a device of an ICP Host Drive.
With ‘gdtsync’ from the /etc directory, you can determine the coordinates of an ICP 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/rgdth
can be generated with:
ln /dev/rdsk/c0b0t0d0s0 /dev/rgdth .
(c0 = HA, b0 = Bus number, t0 = Target-ID 0, d0 = LUN 0, s0 = UnixWare partition).
ƒ
All new SCSI devices will be automatically recognized and a corresponding special-
device-file will be generated
ƒ
Host Drives must be partitioned and a file system/file system(s) must be created. You
can do this with
diskadd cCbBtTdD .
ƒ
When using Direct Access Devices with exchangeable media (e.g., removable hard disks)
that are not reserved for the raw service, a media has to be inserted either when the sys-
tem is booted, or with ICPCON (mount/unmount), otherwise the device is not available
under UnixWare.
ƒ
The ICP UnixWare driver supports Direct Access Devices (e.g., hard disks, removable hard-
disks) as SCSI-raw devices. This is especially important if you use removable hard disks
which you want to exchange with other controllers. How to reserve a device for the
SCSI-raw service is described in the file
space.c on the ICP BTLD disk (example and
documentation).
ƒ
Multi-processor support: The ICP device drivers for UnixWare 2.xy and 7 support multi-
processor systems.
