Chapter I - GDT User's Manual

I.6 Further Information

During the installation of the GDT driver, additional tools are copied into the /etc dire c-

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 a GDT host drive.

For example, on GDT controller 0 we have the host drive 1 which is HA 0, Target-ID 0,

LUN 1 under UnixWare. The corresponding special device file is /dev/rdsk/c0t0d1s0 (c0

= HA, t0 = Target-ID 0, d0 = LUN 0, s0 = UnixWare partition).

By means of "ln /dev/rdsk/c0t0d1s0 /dev/rgdth", the required special device file is ge n-

erated.

If the hardware configuration of a PCI computer is changed (e.g. peripheral expansions

are added or removed), it is likely that the IRQ-to-INT assignment changes, too. In o r-

der to use the GDT controller under UnixWare, it must have IRQ 10.

When using Direct Access Devices with

exchangeable media

(e.g. removable hard disks), a

media has to be inserted either when the system is booted, or with GDTSETUP

(mount/unmount), otherwise the device is not available under UnixWare.
