Therefore, the first Host Drive has target-ID 0 / LUN 0 and the second target-ID 0 / LUN 1.

The formula for determining target ID and LUN from the existing host-drive numbers yields

the following possible combinations for "Direct Access Devices":

This conversion is necessary because the single SCSI devices are not declared to the host

operating system in the order of their SCSI-IDs, but according to the host-drive numbers of

GDTSETUP. The ICP Controller needs host-drives in order to be able to link several SCSI

devices to form a higher structure (i.e., RAID 5). The sequence of the single host-drives can

be changed very easily by having GDTSETUP sort them in its "Configure Host Drives" menu.

In this way, it is also possible to change the boot drive (it had previously been selected as

boot drive because it has the lowest drive number, that is, 0, and is therefore the first drive

to be communicated to the system ). There is one restriction that has to be observed with

Interactive UNIX: Even though gaps are allowed when numbering the host-drives, if there

are several Host Drives, a certain number for a device having a LUN greater than 0 may only

be selected if this number already exists for another device with LUN 0. In other words, a

certain number can only be assigned to a LUN >0 position if the LUN 0 position has also

been assigned.

Example: If a host-drive no. 13 exists (target-ID=1, LUN=5), there also has to be a host-

drive with number 8 (target-ID=1, LUN=0). Please keep this in mind when assigning the
