I.6 Further Information
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).
All new SCSI devices will be automatically recognized and a corresponding special-
device-file will be 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 (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.
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).
Multi-processor support: The ICP device drivers for UnixWare 2.xy and 7 support multi-
processor systems.
