	Ported 10.20 patch PHKL_18390 to TOS.
	(PHKL_18390)
	SR:1653300004 DTS: JAGaa47696 (dup of JAGaa11155)
	Slow PVlink failover
	Diskinfo reports back on an unavailable disk.
	SR:1653300970 DTS:JAGab11365
	SR:1653290395 DTS: JAGaa47016
	A faulty disk can prevent the LVM mirroring from working.

	This patch enables new functionality which adds new I/O
	drivers to support the B1000, C3000, and J5000 systems.
	(PHKL_16926)
	SR:5003434118 DTS:JAGaa23967
	System panics (Data Page Fault) in scsi_destroy_scb
	SR:5003429654 DTS:JAGaa40369
	System panics in c720_invalid_req_done
	SR:4701407890 DTS:JAGaa23080
	Unexpected Disconnect Messages when using pass through
	driver

Defect Description:
	PHKL_25923:
	PCI ID for the 53C895A chip is not in the list of
	supported PCI IDs. Therefore c720 driver does not
	claim this chip.
	Resolution:
	Added 53C895A chip to the list of supported devices.

	PHKL_19084:
	SR:1653300004 DTS: JAGaa47696 (dup of JAGaa11155)
	Slow PVlink failover or diskinfo reporting good disk status
	on an unavailable disk is due to the SCSI INQUIRY command
	returning cached data instead of sending the command down to
	the device."
	Resolution:
	We now ensure an INQUIRY command will be sent down to the
	device when the disk becomes nonresponsive.
	SR:1653300970 DTS:JAGab11365 and
	SR:1653290395 DTS:JAGaa47016
	If a faulty disk sends NOT_READY sense key to SCSI.  The
	current SCSI policy is to retry the request until the disk
	is ready.  This results in a hang IO situation and prevents
	the LVM mirroring from working.
	Resolution:
	LVM-related NOT_READY requests will be treated as
	nonresponse from the disk and will therefore be failed back
	for LVM to handle.
