Determining the SCSI ID
Before you configure your system to support a DDS-format drives, you need
to determine which SCSI ID to use. IDs must be unique for each device on
attached to the SCSI bus.
1
Use the
modinfo
command to identify SCSI controller drivers installed
on the system.
— For FAS or ESP devices:
% modinfo | grep "SCSI Host"
This will produce output similar to the following:
18 501a4000 c3b8 61 1 esp (ESP SCSI Host Bus Adapter Drive)
21 501c8000 9e70 6 1 fas (FAS SCSI Host Bus Adapter Drive)
This indicates that there are two SCSI controllers on the system, an ESP-
based adapter and a FAS-based adapter. For the adapter to which the
new tape drive is attached, you will need to determine what SCSI IDs
are already used.
—
For newer LSI/Intraserver LVD SCSI controllers:
% modinfo | grep "Interserver"
This will produce output similar to the following:
100 78054000 11898 207 1 ithps (ITHPS-5.02.00 Intraserver)
100 78054000 11898 207 1 ithps (ITHPS-5.02.00 Intraserver)
2
Determine the SCSI IDs of the existing devices attached to the SCSI
controller:
For all adapters:
% dmesg | egrep ".*xxx.*target" | sort | uniq
where
xxx
= the type of adapter (
esp
,
glm
,
fas
or
isp
), as appropriate.
For example, for an ESP-based adapter:
