lsscsi: command not found

To list the SCSI devices on your system, use a utility that walks the device paths provided by sysfs. One of the most succinct tools is lsscsi. Here’s what you can expect when you run it:

$ lsscsi
[0:0:0:0]    disk    ATA     WDC WD3200AAJS-2  01.0  /dev/sda
[2:0:0:0]    disk    FLASH   Drive UT_USB20    0.00  /dev/sdb

The first column identifies the address of the device on the system, the second describes what kind of device it is, and the last indicates where to find the device file. Everything else is vendor information.

Use yum -y install lsscsi to install the lsscsi package, and enter lsscsi to verify that installation was successful:

# yum -y install lsscsi
# lsscsi
