Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

menuconfig SCSI_DH
	bool "SCSI Device Handlers"
	depends on SCSI
	default n
	help
	  SCSI Device Handlers provide device specific support for
	  devices utilized in multipath configurations. Say Y here to
	  select support for specific hardware.

config SCSI_DH_RDAC
	tristate "LSI RDAC Device Handler"
	depends on SCSI_DH && SCSI
	help
	If you have a LSI RDAC select y. Otherwise, say N.

config SCSI_DH_HP_SW
	tristate "HP/COMPAQ MSA Device Handler"
	depends on SCSI_DH && SCSI
	help
	If you have a HP/COMPAQ MSA device that requires START_STOP to
	be sent to start it and cannot upgrade the firmware then select y.
	Otherwise, say N.

config SCSI_DH_EMC
	tristate "EMC CLARiiON Device Handler"
	depends on SCSI_DH && SCSI
	help
	If you have a EMC CLARiiON select y. Otherwise, say N.

config SCSI_DH_ALUA
	tristate "SPC-3 ALUA Device Handler"
	depends on SCSI_DH && SCSI
	help
	  SCSI Device handler for generic SPC-3 Asymmetric Logical Unit
	  Access (ALUA).

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
