How to Detect Devices Attached to Servers

This topic describes how to detect devices that are attached to data mover servers and how to detect SCSI devices attached to specific platforms.

All devices appear as a link file in the /dev/CA directory on data mover servers, as illustrated by the following screen:

All devices appear as a link file in the /dev/CA directory on data mover servers.

The DeviceSerialMap file contains the information about changers and devices that are attached to the data mover server.

Note: You can access all types of SCSI devices using the sg driver. The sg device mapping configurations can be viewed in the /proc/scsi/sg/devices directory or the /proc/scsi/sg/device_strs directory.

SUN 10 operating systems use two types of SCSI drivers: st and sgen. You can determine the types of drivers and changers from the /etc/driver_aliases file. The following screen illustrates that the driver type is st and the changer type is scsiclass,01.

Command prompt: Example-st driver with changer scsiclass,01.

The following list describes the syntax for st drivers.

Note: Optionally, you can obtain a device list from the /kernel/drv/st.conf file.

The following list describes the syntax for sgen drivers:
