bus-scsi

Expose SCSI disk information via automatic attributes under the bus.scsi namespace.

Requirements

This cookbook requires Chef 12.7+.

Platforms

• Linux with libudev-147+ (tested with CentOS 6)
• Windows (tested with Windows Server 2012R2 & 2016)

Usage

You just need to load the cookbook to get access to the SCSI automatic attributes.

• In a cookbook, add a dependency to bus-scsi in your cookbook's metadata.
• On a node, add the bus-scsi::default recipe to your run-list.

You can disable these attributes by turning the bus_scsi_disabled setting to true in the Chef config.

Attributes

The bus.scsi namespace is a hash with one entry per SCSI disk. For each disk, the hash key is the "host:channel:target:lun" quadruplet and the value is another hash with the following attributes exposed:

Attribute	Description
host	SCSI adapter number
channel	SCSI channel number
target	SCSI id number
lun	SCSI Logical unit number
model	Vendor model string
fwrev	Firmware revision identifier
serial	Disk serial number
size	Size of the disk in bytes
wwn	World wide number identifier (only in Linux)
devnode	Device entry in /dev (only in Linux)
host_pci	PCI location of the host adapter this device depends on (only in Linux)

Recipes

This cookbook has a single bus-scsi::default recipe which does nothing. It can be used to load the cookbook from a run-list.
