# SCSI
|
|
|
|
## Introduction
|
|
|
|
This plugin adds support for SCSI storage hardware. Most SCSI devices are enumerated and some UFS
|
|
devices may also be updatable.
|
|
|
|
Firmware is sent in 4kB chunks and activated on next reboot only.
|
|
|
|
## Firmware Format
|
|
|
|
The daemon will decompress the cabinet archive and extract a firmware blob in
|
|
an unspecified binary file format.
|
|
|
|
This plugin supports the following protocol ID:
|
|
|
|
* org.jedec.ufs
|
|
|
|
## GUID Generation
|
|
|
|
These device use the SCSI DeviceInstanceId values, e.g.
|
|
|
|
* `SCSI\VEN_HP&DEV_EG0900JETKB&REV_HPD4`
|
|
* `SCSI\VEN_HP&DEV_EG0900JETKB`
|
|
* `SCSI\VEN_HP`
|
|
|
|
## Vendor ID Security
|
|
|
|
The vendor ID is set from the vendor, for example set to `SCSI:HP`
|
|
|
|
## External Interface Access
|
|
|
|
This plugin requires only reading from sysfs for enumeration, but requires using a `sg_io ioctl`
|
|
for UFS updates.
