Before you can use them you have to create a special device file named /dev/rgdthby 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 HostDrive. Usually the first Host Drive has the coordinates c0b0t0d0.A special device file (character device) is ‘/dev/rdsk/c0b0t0d0s0. In this case, /dev/rgdthcan 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. Youcan 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 availableunder 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 diskswhich you want to exchange with other controllers. How to reserve a device for theSCSI-raw service is described in the file space.c on the ICP BTLD disk (example anddocumentation). Multi-processor support: The ICP device drivers for UnixWare 2.xy and 7 support multi-processor systems.
