General description

This section describes how to find proper "/dev/sg" device for CHARON mapping

Procedures of finding the target "/dev/sg" device

Method 1

Open a terminal console and issue:

The output will look something like:

[0:0:0:0]    disk    VMware   Virtual disk     1.0   /dev/sda   /dev/sg0
[0:0:10:0]   tape    COMPAQ   SDLT320          5F5F  /dev/st0   /dev/sg9
[0:0:11:0]   tape    COMPAQ   SDLT320          5F5F  /dev/st1   /dev/sg10
[0:0:12:0]   mediumx COMPAQ   MSL5000 Series   0520  /dev/sch0  /dev/sg11
[4:0:0:0]    cd/dvd  NECVMWar VMware SATA CD01 1.00  /dev/sr0 /dev/sg

If the "lsscsi" command is not installed on your system, use "yum install lsscsi" to make it available. If you cannot install "lsscsi", use method 2 or method 3 described below.

Method 2

Open a terminal console and issue:

The output will look something like:

The fifth field ("type") is the device type.

The "N" in the "/dev/sgN" is the line number in this table (starting from 0) corresponded to the devices CHARON-AXP will use.

Thus "/dev/sg0" will be CD-ROM mapping in this example.

Method 3

On a freshly booted system, issue the following command:

The output will look like that:

 This table lists all the devices, not only the real SCSI ones (SATA/IDE for example). CHARON supports only real SCSI devices.
