Types

type Device

type Device struct {
	// DevPath represents the disk hardware path.
	// The general format is like /sys/devices/pci0000:ae/0000:ae:02.0/0000:b1:00.0/host2/target2:1:0/2:1:0:0/block/sdc/sdc
	DevPath string `json:"devPath,omitempty"`

	// DevName the general format is /dev/sda
	DevName string `json:"devName,omitempty"`

	// DevType such as disk, partition
	DevType string `json:"devType,omitempty"`

	// Major represents drive used by the device
	Major string `json:"major,omitempty"`

	// Minor is used to distinguish different devices
	Minor string `json:"minor,omitempty"`

	// SubSystem identifies the device's system type, such as block
	SubSystem string `json:"subSystem,omitempty"`

	// Bus represents the bus type of the device, such as USB, SATA
	Bus string `json:"id_bus,omitempty"`

	// FSType represents the filesystem type such as ext4, ntfs
	FSType string `json:"id_fs_type,omitempty"`

	// Model represents the specific model of the storage device, usually specified by the manufacturer
	Model string `json:"id_model,omitempty"`

	// WWN represents the World Wide Name(WWN) of the device.
	// The general format is like 5001b444a89e5acd.
	WWN string `json:"id_wwn,omitempty"`

	// PartTableType represents the partition table type, such as gpt or mbr
	PartTableType string `json:"id_part_table_type,omitempty"`

	// Serial represents the Serial Number(SN) of the device.
	// The general format is like 162061400553
	Serial string `json:"id_serial,omitempty"`

	// Vendor represents the manufacturer of the device
	Vendor string `json:"id_vendor,omitempty"`

	// IDType specifies the detailed type of the device according to udev rules, such as 'cd', 'disk', or 'partition',
	// providing a finer classification than DevType, usually the values of IDType and DevType are the same
	IDType string `json:"id_type"`

	// PartName such as EFI System Partition
	PartName string `json:"partName"`

	// Name is the name of the device node sda, sdb, dm-0 etc
	Name string `json:"name"`

	// DevLinks is a symbolic link array for the device, containing all symbolic links for the device
	DevLinks []string `json:"devLinks"`
