Having to determine the Target ID and LUN in such a complicated manner might seem
rather awkward. However, it is necessary to do so because the ICP Controllers have more
than one SCSI channel, whereas UNIX can only manage host adapters with one SCSI chan-
nel. Therefore, the ICP UNIX driver has to make the appropriate transformations.
Configuration Example:
In the PCI computer are two ICP Controllers (HA 0 = 1st ICP, HA 1 = 2nd ICP), each with two
SCSI channels.
1 hard disk as Host Drive no. 0 on HA0
1 hard disk as Host Drive no. 0 on HA1
1 hard disk as Host Drive no. 1 on HA1
1 Streamer SCSI-ID 2, LUN 0 on SCSI channel A of HA0
1 CD-ROM SCSI-ID 3, LUN 0 on SCSI channel A of HA0
1 DAT SCSI-ID 2, LUN 0 on SCSI channel B of HA1
Result:
