Symptoms:
	PHKL_29681:
	( SR:8606325198 CR:JAGae87488 )
	After system panic, the crash dump was not saved by the
	SCSI c8xx dump driver, instead, one of the following
	messages was displayed on the console :

	ERROR:  can't open dump device <device>.  Dump aborted

	                OR

	ERROR:  can't open first dump device <device>.  Dump
	aborted

	This problem was seen when Seagate disk devices were
	configured for dump and were connected to A5149A,
	A5150A, A6828A, A6829A, A5838A SCSI HBAs and
	Ultra2/Ultra160 core I/O cards.

Defect Description:
	PHKL_29681:
	( SR:8606325198 CR:JAGae87488 )
	The SCSI c8xx dump driver tries to open the Seagate
	disk device to save the crash dump.  During the open
	operation, the driver sends a tagged request sense
	command in order to find more information about the
	failure with the previous command.  The Seagate disk
	device, however, did not respond to this tagged
	request sense command correctly, thereby causing the
	dump operation to fail with the "Dump aborted"
	message displayed on the console.

	Resolution:
	The SCSI c8xx dump driver has been modified to send an
	untagged request sense command instead of the tagged
	request sense command.

Enhancement:
	No
