Defining a Logical SCSI Bus
At boot, the logical SCSI manager creates the logical SCSI buses defined in the
CONF file (in the LIF on the flash card or boot disk). The default CONF file provides
definitions for the standard logical SCSI buses in a system. Normally, you do not
need to modify these definitions. However, you might need to add or modify the
logical SCSI buses if you add a disk expansion cabinet or move a SCSI controller to
a new location.
You can use the lconf command to add logical SCSI buses to the current
operating session. To permanently add logical SCSI buses, or to delete or modify
existing logical SCSI buses, you must edit the /stand/conf file manually and
copy it to the CONF file on the flash card or boot disk. For more information, see the
lconf(1M) and conf(4) man pages.
Figure 5-6 illustrates a configuration for a hypothetical system with both internal
disks and external disks in an expansion cabinet. The configuration has six logical
SCSI buses using nine SCSI ports as follows:
NOTE
This example is for illustration only; expansion cabinets are not
supported for Continuum systems running HP-UX version 11.00.03. A
typical Continuum Series 400/400-CO system includes lsm0-4, but not
lsm4 or lsm5.
■ Two dual-initiated buses, lsm0 and lsm1 (hardware paths 14/0/0 and
14/0/1), are provided for the internal disk drives.
■ Two single-initiated buses, lsm2 and lsm3 (hardware paths 14/0/2 and
14/0/3), are provided for external tape and CD-ROM devices.
■ One dual-initiated bus, lsm4 (hardware path 14/0/4), is provided for
external disk drives (in a disk expansion cabinet).
■ One single-initiated bus, lsm5 (hardware path 14/0/5), is provided for
external disk drives (in a disk expansion cabinet).
The following entries define the logical SCSI buses on a system with a
StorageWorks disk enclosure, as shown in Figure 5-6:
lsm0=0/2/7/1,0/3/7/1:id0=15,id1=14,tm0=0,tp0=1,tm1=0,tp1=1,rt=1,bt=1
lsm1=0/2/7/2,0/3/7/2:id0=15,id1=14,tm0=0,tp0=1,tm1=0,tp1=1
lsm2=0/2/7/0:id0=7,tm0=1,tp0=1
