77. urther Information During the installation of the GDT driver additional tools are copied into the etc di rectory 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 ICP Controller 0 we have the Host Drive which is HA 0 Target ID 0 LUN I under Interactive Unix The corresponding special device file is dev rdsk cOtOdl1s0 c0 HA t0 Target ID 0 d0 LUN 0 sO Unix partition By means of In dev rdsk c0t0d1sO dev rgdth the required special device file is generated A media change can be made with UNIX commands MOUNT and UNMOUNT Please make sure that the removable hard disk keeps its GDTSETUP drive number when changing the media otherwise a separate ID LUN entry is necessary for each single media since the drive number depends on the media and not the device containing it If you change the hardware configuration of your PCI computer system it may happen that the GDT is assigned to a different IRQ as it was assigned during the installation and operation of UNIX In this case you need to run the installation again with a GDT driver for the new IRQ or change the hardware configuration so that the old IRQ is available for the GDT again Intelligent Computer Peripherals gt Chapter O GDTSETUP in Detail 22 0 GDTSETUP in Detail We refer to firmware RAIDYNE as the opera
