Unixware Bus Number, Target Id And Lun; Configuration Example - Intel SRCMR - RAID Controller User Manual

UnixWare Bus Number, Target ID and LUN

Target IDs and LUNs for "Non-Direct Access Devices" (devices like streamers, tapes and
CD-ROMs and therefore not configurable via StorCon), are directly assigned to the SCSI ID and
the channel of the Intel RAID Controller SRCMR. Host drives are assigned in increasing order to
the free coordinates (bus number and target ID;LUN is always 0).

Configuration Example

In the PCI computer are two Intel RAID Controller SRCMRs (HA 0 = 1st Intel RAID Controller
SRCMR, HA 1 = 2nd Intel RAID Controller SRCMR), 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 B of HA0
1 DAT SCSI ID 2, LUN 0 on SCSI channel A of HA1
The resulting HA, Bus, Target ID and LUN are indicated in Table 13.
Table 13.
