LsSCSI - command /usr/bin/lsscsi

This module provides processing for the output of the /usr/bin/lsscsi command.

class insights.parsers.lsscsi.LsSCSI(context, extra_bad_lines=None)[source]

Bases: insights.core.CommandParser

This parser reads the output of /usr/bin/lsscsi into a list of dictionarys. Each item is a dictionary with six keys:

  • HCTL - the scsi_host,channel,target_number,LUN tuple

  • Peripheral-Type - the SCSI peripheral type

  • Vendor - the vendor name

  • Model - the model name

  • Revision - the revision string

  • Primary-Device-Node - the primary device node name

data

List of the input lines, where each line is a dictionary having the keys identified above.

Type

list of dict

Parsing refers to http://sg.danny.cz/scsi/lsscsi.html.

Sample input:

[1:0:0:0]    storage IET      Controller       0001  -
[1:0:0:1]    cd/dvd  QEMU     QEMU DVD-ROM     2.5+  /dev/sr0
[1:0:0:2]    disk    IET      VIRTUAL-DISK     0001  /dev/sdb
[3:0:5:0]    tape    HP       C5713A           H910  /dev/st0

Examples

>>> lsscsi[0] == {'Model': 'Controller', 'Vendor': 'IET', 'HCTL': '[1:0:0:0]', 'Peripheral-Type': 'storage', 'Primary-Device-Node': '-', 'Revision': '0001'}
True
>>> lsscsi.device_nodes
['-', '/dev/sr0', '/dev/sdb', '/dev/st0']
>>> len(lsscsi.data)
4
>>> lsscsi[1]['Peripheral-Type']
'cd/dvd'
